The probe zero value is zero at this time to get the value of the probe

Work process just to make a small amount of supplement. Hydraulic piston pump can be operated single-well, you can also build pump centralized management, a wide range of displacement adaptation, from tens to thousands of cubic diesel flow meter meters per day, etc., suitable for deep, high-lift wells, heavy oil, inclined. The advantage is the displacement can be adjusted, from the convenience of the pump tubing can not afford the operation and management. Pump efficiency up to 85%. The disadvantage is that the ground have to build a high-pressure pipelines, power fluid to be processed, an increase of well construction and management costs.

With various flow sensors or transmitters

In addition to the loss of the signal actually decile, there partly because Zhang attenuation distribution device itself, so larger than the calculated value. As is often the loss of value of the two allocator works 3.5dB, 4 dispensers often lost value 8dB. , the frequency range: a dispenser used throughout the cable television network, mobile fuel dispenser and therefore should have a broadband frequency characteristic. Return loss , the RF characteristics usually pass splitter connected to the branch or trunk line midway by a main input terminal, an output terminal and a number of main branches constitute the output, the output of which branch only get main Road, a small portion of the input signal, the majority of the output signal is still along the main road and continue to transmit backwards.

The primary work of the display dispenser

Move around the reflector so that the echo reaches a maximum angle of incidence corresponding to the point at this time is that the probes or the K-scale values. Material Velocity Calibration find R100mm described in accordance with a maximum parts for pumps reflected waves makes it possible to display dispenser adjust the display range is displayed on the screen of the arc of the display dispenser second echo select gate way for the double gate, A gate with an echo adjustment intersect, regulating B gate intersects with the second echo, adjust the speed of sound value makes the status line sound path measurement is 100, velocity values ??obtained at this time is the actual velocity values of the material.

How to buy car refueling machine

The diesel fuel flow meter is in different forms and has played a very good role in both the business and the individual's work, so the product is essential, but the product also needs to pay attention to a lot of things at the time of purchase. The need to choose a different tanker, like a car refueling machine is one of them, with great mobility, when the work will be more convenient, with the form of vehicle equipment on the refueling, there is no space constraints, Very convenient.
Car refueling machine in the purchase of the time should also pay attention to a lot of problems, like the product manufacturer is the most important, the manufacturer's technology related to the quality of the product, the quality of the bad use of the process will be greatly affected, The power of the tanker should also pay attention to, after all, the car's products in the volume and weight are limited, otherwise it is difficult to achieve the purpose of mobility, so the power will be limited, of course, the car's tanker does not need Too much power, as long as the performance is very good can.
tank level gauge system in the use of the time to ensure that the configuration to ensure complete, poor configuration in the use of the time will be affected, at least the configuration is the tip, it is necessary for the configuration of the tanker, of course, the price will Have the effect, but the most important thing is the product function, only the function will have a good role.

How to choose a tanker

The fuel transfer hand pump is an indispensable product for work and life, bringing great convenience to everyone's life. Today's transportation equipment is essential and presents a rising trend, so the fuel is needed. Plus fuel when they need more professional equipment, can we save more time, and the tanker is such a device, when the fuel will be more fast, but this equipment needs not only the occasion Gas stations, in many enterprises also need such equipment, so we must choose the right tanker.
How to choose the auto fuel dispenser we take a look at the gas station is usually used in the relatively large power of the machine, the power will be faster speed, when the operation will be more rapid, a lot of services have a very good help, Of course, you can also choose the gun tip of the tanker, the actual use of the effect will be better, and faster and faster.

Use the tanker to pay attention to what problems

Each product is to appear in order to better serve the public, in the actual use of more labor to save, which is the purpose of enterprises to create products, like the emergence of the fuel dispensing machine, to a large extent to meet everyone The need for refueling, this way of refueling will be more convenient, the use of high-tech technology to make fuel more intelligent is the advantage of this product, so in many industries will use this product, so that the work efficiency is very large improve.
There are many types of gas station dispenser, each type of product has a very good effect, so also need to purchase, the greater the power of the product will be higher in the price, usually like this product are in the refueling Station use, to the staff and consumers a great convenience, the power of disaster when the fuel will be faster, but in the specific operation process also need to pay attention to the phenomenon of adding oil, in the busy time will appear This is the error, which is the attitude of the postgraduate in the work of the logistics of what kind of products, all with intelligent refueling equipment for everyone's work to bring great convenience.
Tanker in the work of the time should also pay attention to a lot of problems, especially in the safety of the problem even more attention to the fuel inside the tanker will encounter a fire, so when the fuel must be the first time the device flame Can be fueled, such things in a lot of gas stations will appear, the driver will not let the car trouble, so that once the consequences are very serious, the tanker should always clean, clean the product, keep the product performance, The product will not be contaminated.

Effect of Temperature on the Fuel Consumption of Tanker

The same quality of fuel at different temperatures when the volume is not the same, China's petrol station management system is currently ignoring this point. At present, the measurement results of the tanker on the market are mostly the value of the oil temperature at non-standard temperature, and the tanker has no volume temperature correction function technically. If the tanker does not consider the temperature change factor, the measured value is not the standard temperature of 20 ℃ volume, will inevitably affect the measurement of the value of the unity and accuracy, resulting in oil sales error. According to the International Recommendation OIML R117-1995 "Non-aqueous liquid measurement system", the gasoline flow meter can use the conversion device to modify the volume, the actual volume measurement results into the standard temperature (15 ℃ or 20 ℃) ​​under the volume For our country, the standard temperature is 20 ℃).

Self-styled refueling gun pressure sensing system

fuel transfer hand pump for kerosene, gasoline, diesel and other light oil filling operations. It has a separate body with the gun body of the sealed pressure of the working system, when the oil gun main valve to open high-speed oil flow through the return valve, due to the special structure of the valve assembly design will make pressure inside the system pressure.
temperature probe calibration When it is in normal working condition, its pressure-sensitive system will be through the pressure inside the tubing in the pipeline to continue to get gas to maintain the pressure-sensitive diaphragm up and down the basic pressure in a state of balance. When the filling surface rises and closes the ventilation port (at this time the container is full) pressure within the system will quickly increase the negative pressure, pressure sensor on both sides of the pressure loss on both sides of the pressure (upper negative pressure) The diaphragm will drive the switch card to the negative side of the movement of the bolt off the file, which in 0.3 seconds self-styled refueling gun to complete self-styled closure action.

Do you know why the gas station disables the phone?

1, the phone used in the petrol station, will produce a fire phenomenon
In the use of mobile phones will find this phenomenon, when the phone calls, the surrounding electrical interference is relatively large, such as the radio instantaneous noise, TV screen interference, etc., the main reason is the phone calls or phone calls, around the phone The main line, such as the antenna, circuit boards, panels, etc., will produce induced electromotive force, the electromagnetic field is the strongest, and the magnetic field is the strongest, the conductor in the magnetic field, the storage tank calibration methods includes: shell, cable, circuit board, internal line, Especially the components on the phone, the resulting induced electromotive force is the strongest induction electromotive force will produce the induced current, if the phone antenna is not connected, the phone inside the circuit board contact is not good, the battery contacts are likely to produce loose phenomenon At the same time, in the mobile phone signal electromagnetic field items will also produce static accumulation, static electricity is also the main cause of the phenomenon of ignition.
2, the gas station can form explosive gas
Gas station is a special place, likely to cause gasoline, natural gas and other explosive gas leakage, especially in the process of refueling oil and gas generated in the air, especially in summer, high temperature, gasoline volatilization, resulting in high concentration of oil and gas stations Gasoline is the most dangerous in liquid fuels. Gasoline is a mixture of hydrocarbons containing 5 to 12 carbon atoms, lighter than water and insoluble in water, volatile at room temperature, temperature probe calibration than air, so easy to accumulate In the low-lying, with the air to form an explosive mixture, the explosion limit of 1.3% to 6%, petrol steam minimum ignition energy is only 0.2 mJ, so any small sparks or naked eye can not see the static electricity will lead to space gas explosion combustion.
Mobile phone in the call or in the process of mobile phone switch, the internal will produce sparks. Oil and gas diffusion when all-pervasive, once into the phone, you may encounter a spark, and this spark is enough to ignite the explosion within the limits of explosive gas Fire accident occurred.
3, the mobile phone signal electromagnetic field will affect the fuel system computer motherboard work stability
Mobile phone in the call, a strong mobile phone signal electromagnetic field will be connected with the portable fuel transfer pump in the power supply lines, communication lines on the induced electromotive force, that is, the formation of interference pulses, interference pulse into the tanker and control machine, will affect the refueling equipment computer Motherboard work stability, which will cause the program is not running properly, crash, data loss, parameter changes, measurement is not accurate and some difficult problems.

Reminder self-refueling anti-static

In the car when the temperature probe calibration, we all know that a try is to use the refueling gun to the car refueling process can not call the car to turn off these safety knowledge is a lot of people know, but especially in the north, air dry Cold, is the static season, in the gas station to use the gas station dispenser gun self-refueling, if not pay attention, these hidden static electricity may cause a fire or explosion. How to eliminate static electricity?
To prevent electrostatic hazards, in the design of self-service tanker has been taken into account, so the tanker designed to provide the place to discharge.In general, the tanker on the metal keyboard is directly in contact with the ground, the owner before the need to refuel In the keyboard to enter their own petrol station automation system information, this process is equivalent to carrying the static electricity on the discharge, eliminating the body carrying static electricity.
In addition, the autonomous tanker also has a circular electrostatic discharge device, the above will remind you to touch before hand to release static electricity, the process is actually to remind you through its friction, the release of the body carried by the static , To prevent the next in the process of filling the hidden danger.

Refueling machine prices simply talk about the working principle of the tanker

   The petrol station management system is the core equipment of the gas station. In the era of increasing the number of cars and motorcycles, the number of tankers is increasing every year. The tanker can be divided into two types: self-priming pump fuel tanker and submersible fuel tanker , The following tanker price is simple under the two tanker their working principle:
    Self - priming pump fuel tanker works
Lifting the oil gun, the switch signal into the computer device to start the motor at the same time open the solenoid valve, the motor drive pump oil into the pump, pressurized oil and gas separation, the gas was discharged from the machine, the oil into the automatic tank gauge systems to promote the piston for reciprocating motion. The flowmeter drives the indexing plate in the sensor and generates a pulse electrical signal into the computer unit The flowmeter piston outputs a certain number of pulsed electrical signals each time a cycle is passed through a fixed volume of oil and into the computer Operation shows the realization of the measurement and control of the amount of oil through the measurement of oil through the electrostatic transmission hose, oil gun from the oil tank to the oil supply.
    Submersible pump fuel gas station management software working principle
The oil pressure signal is sent to the computer device, the electromagnetic device is opened after the computer device is processed, and the oil supply signal of the submersible pump is sent to the electric control device, and the electrical control device starts the submersible pump oil supply. The high pressure oil enters the flow meter through the filter The flowmeter pistons each time a cycle is passed through a certain fixed volume of oil, the sensor outputs a certain number of pulsed electrical signals, the flowmeter sends a pulse to the computer, , Into the computer device to calculate the operation to achieve the measurement and control of oil consumption.After the measurement of oil through the static electricity oil hose, oil gun from the oil tank to the oil supply.

In the use of gas station management system when you need to pay attention to some of the details of the problem, often these details of the problem and led to a lot of big problems, so the operation of this device is still very skilled grasp of the job, in the use of diesel fuel tanker Time must first check whether the equipment oil spill, to keep the machine clean, so that refueling more clean and tidy, but also regularly clean up the fuel card management, so that the function of the machine will not be affected in the actual operation also need to pay attention to a lot of Problems, these problems in the equipment have a detailed description, must be observed, the operation will be more secure.

submersible fuel pump become a lot of mobile equipment indispensable items, but also nowadays the most intense material, like this product how to be able to enter the mobile device on the need for a professional machine, the tanker is the best professional refueling machine, when the refueling More convenient, but also more helpful to the staff, this product in the use of time to have full control of technology, when the refueling will be more clean and tidy.
High intelligence era Many industries will infiltrate such a technology, tanker also infiltrated such a technology, intelligent way of refueling, the staff more helpful, we can see in many gas stations have the kind of fixed refueling equipment, as long as Input costs, refueling equipment will automatically generate the amount of automated fuel management system in the number will automatically stop after the number, this intelligent equipment to a large extent the release of more labor, but also save a lot of costs, but also their own refueling , As long as the smart terminal on the card can be their own fuel, very convenient and more time-saving.

The gasoline meter is in different forms and has played a very good role in both the business and the individual's work, so the product is essential, but the product also needs to pay attention to a lot of things at the time of purchase, depending on the The need to choose a different tanker, like a car refueling machine is one of them, with great mobility, when the work will be more convenient, with the form of vehicle equipment on the refueling, there is no space constraints, Very convenient.
temperature probe calibration machine in the purchase of the time should also pay attention to a lot of problems, like the product manufacturer is the most important, the manufacturer's technology related to the quality of the product, the quality of the use of the process will be a great impact in the The power of the tanker should also pay attention to, after all, the car's products in the volume and weight are limited, otherwise it is difficult to achieve the purpose of mobility, so the power will be limited, of course, the car's tanker does not need Too much power, as long as the performance is very good can.
Car fuel tanker in the use of the time to ensure that the configuration to ensure complete, poor configuration in the use of the time will be affected, at least the configuration is the tip, it is necessary to configure the tanker, of course, the price will Have the effect, but the most important thing is the product function, only the function will have a good role.

The gasoline flow meter is an indispensable product for work and life, bringing great convenience to everyone's life. Today's transportation equipment is essential and presents a rising trend, so the fuel is needed. Plus fuel when they need more professional equipment, can we save more time, and the tanker is such a device, when the fuel is also more fast, but this equipment needs not only the occasion Gas stations, in many enterprises also need such equipment, so we must choose the right tanker.
How to choose the petrol station management system we take a look at the gas station is usually used in the relatively large power of the machine, the power will be faster speed, when the operation will be more rapid, a lot of services have a very good help, Of course, you can also choose the gun tip of the tanker, the actual use of the effect will be better, and faster and faster.
Enterprises to buy a tanker when the small tanker will be small, small products in the function is the same, but in the smaller size, easy to store, but also in the moving time will be more convenient, the actual use also There are car type, in the field will be more suitable for the operation, so when you choose the tanker will be used according to the needs of the occasion, not only effective and the cost will be more reasonable.

The price of the tanker is not a decisive factor

The gas station dispenser has become the most important equipment in life, in many machines need such equipment, to be able to work better and more convenient life, many companies also need to buy the tanker, in order to make the production of enterprises can be better Run, you need to refuel the machine can use this equipment, simple and convenient, of course, the price of the fuel dispensing machine will be a big factor, the price is too high is not very good, the price is too low and not easy to use, at the time of purchase It is necessary to carefully choose.
Tanker prices are different in each manufacturer, because the manufacturers in the material and technology investment are not the same, big brands in the technology will be greater investment, and the material will be better, in the market When the price may be high, but it is not very outrageous level, relatively large brands of products in the price is also in accordance with the positioning of the market, the deviation will not be great. Tanker price is not a very important factor in the purchase of the tanker when the performance to understand clearly, to be able to protect the quality of the product.

Small tanker to the production of enterprises to promote the role

automated fuel management system is very suitable for individuals and businesses to use, because in the body to occupy a great advantage, so when placed in the area will be reduced, the enterprise can save more space, space on the production will help, Business space requirements, space is too small will affect the progress of the work, but also to the staff to increase the trouble, this tanker will be able to save more space, so that production and work can be carried out smoothly.
Small refueling machine because of the smaller size, the required materials will be less, of course, the investment in technology is the same, but will be reduced in the configuration, of course, this also depends on what type of tank calibration software, from the overall Point of view, due to the smaller power consumption of materials is also less in the cost of relatively small, the market price will be much lower, which is another advantage of this tanker.
As a small refueling machine has many advantages, so popular in the market, as many enterprises indispensable equipment, in the production of enterprises played a very good role in promoting.
