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.

What is automatic diesel fuel flow meter

Requirements have been considered and sets out guidelines for equipment maintenance issues. New and existing system owners and operators must provide a leak detection method, or a combination of leak detection methods for installation, calibration, operation and maintenance according to the manufacturer's instructions, including operability diesel fuel flow meter and operational status of routine maintenance and maintenance checks. "this guidance applies to all terms and leak methods, including tanks, pipelines, oil pan, groundwater wells, etc. also supports third-party assessment program these views. each ATG testimonial presented with the same statement:. "only in the case of the seller regarding the installation and operating diesel fuel flow meter instructions are complied with, the above performance evaluation is effective" all subsequent introduction of federal documents, including maximum use of your automatic oil tank level gauge system and underground storage tanks reference manual inspectors have made the same recommendation.

The main function of marine fuel dispensers

Marine fuel dispensers dispensing pumps are assigned short, it mainly consists of chip secondary pump, high pressure pump, governor, oil fuel distribution marine fuel dispensers control valves and other components, the main function of these components is as follows: VE-type dispensing pump slip chip secondary pump - will fuel further appropriate booster to ensure the necessary allocation into the oil pump and the outlet pressure with a regulator to control marine fuel dispensers. High pressure pump - into the oil from the pump oil, and with oil effect. Governor - can automatically change the amount of oil according to the load of diesel fuel dispensing pumps, in order filling station pump to meet the needs of the diesel engine work. Automatic fuel supply advance angle adjustment mechanism - can supply advance angle changes with the speed or load automatically earlier or later, thus improving the performance of diesel engines. Oil control valve - according to the engine load changes, changes in fuel supply. Other devices to improve engine performance, such as the start enriched and torque correction devices.

Gas nozzles

1. Failure profile; The gas nozzles is an important component of the engine, mainly responsible for receiving the signal from the computer ECU and receiving the command to spray the oil. General use of the oil pulse width to determine. In general, there will be engine jitter after failure, or even fire.

2. Required tools; (1) automobile special detection multimeter. (2) shida tool 124 pieces (3). Stethoscope.(4) special test light for automobiles (5).

3. Method; (1). Use the test lamp to check whether the wiring harness on the nozzle is dc power supply.

(2) use a multimeter to check whether the wiring harness on the nozzle of the nozzle has a direct current of about 12 volts. If there is no power supply or low power supply, check if the power supply line is in the position of iron, resulting in low working power of the injector.

(3). Listen to the work sound of the injector by the stethoscope and whether there is a rattling noise.

(4) if there is a power supply voltage. It is possible to use a multimeter to test the signal line of the injector to the computer stitching. Or check if there is a short circuit or iron.

4. Matters needing attention; (1) the car USES direct current, and the multimeter hits DC position to test the voltage.

(2) pay attention to the protection and protection of the line.

(3). Pay attention to the correct use of the fender guard and protect the vehicle. Pack up
