Battery with long-lasting lithium battery

Battery with long-lasting lithium battery, single function integrating meter battery service life of up to 5 years above, petrol dispenser multi function display table battery service life can reach more than 12 months.Turbine flowmeter in the beginning, the sensor should be slowly filled with medium, and then open the exit valve, vehicle identification system , the sensor is not the medium state when the impact of high-speed fluid. Intelligent integrated turbine flowmeter is designed for explosion proof, which can show the total flow rate, instantaneous flow rate and flow rate of full percentage. 

gasoline flow meter

When used, should be kept the measured medium clean, gasoline flow meter ,free of impurities such as fiber and particles.Turbine flowmeter is a precision instrument of flow ,measurement, flow totalizer and the corresponding flow totalizer supporting can be used for measurement of liquid flow and the total. Widely used in oil, chemical, metallurgy, research and other fields of measurement, control system. The turbine flow sensor equipped with sanitary connector can be used in pharmaceutical, food and other industries.

diesel fuel flow meter turbine flowmeter measurements

While the pulse frequency through frequency - voltage converter to indicate flow rate. Impeller speed is proportional to gasoline flow meter, the number of revolutions of the impeller is proportional to the total flows. Output of the turbine meter is the frequency modulated signal, not only to improve the anti-interference detection circuit, and simplifies the flow detection system. diesel fuel flow meter turbine flowmeter measurements. It is first converted to rotational speed of the turbine flow rate, then speed is converted into an electrical signal proportional to flow. This meter is used to detect instantaneous flow rate and total flow totalizer, the output signal frequency, easy to digitize. 

When quantitative refueling china fuel dispenser

When quantitative refueling china fuel dispenser, the solenoid valve is fully open, and when the amount of fuel remaining 0.3 to 0.5 l, Computer announced the closure large flow signal, low flow continued to fuel the preset number, and finally closed low flow, a closed motor, This does not render overpayments oil appearance. When the solenoid valve diaphragm remove or turn inside use, fuel quantity reaches the preset number, the board announced that the signal can not be a closed circuit, continuous high flow fuel, so that appears to show plate number greater than the preset number refueling.
Thus, when the solenoid valve can not be opened so that no oil auto fuel dispenser, should be properly repaired. First, you should see some of the solenoid valve control circuit, such as the zero line is not entered, the light valve plate is not damaged. Secondly, look up inside the valve solenoid valve itself wrong problems, such as the valve is not open circuit coil, diaphragm aperture is not obstruction. If the solenoid valve itself is wrong and can not be amended, should be replaced with new solenoid valve. Also at the time of purchase to pay attention to the type solenoid valve being replaced together.

Master slide valve located in the dead center

Master slide valve located in the dead center. In this case, high pressure power fluid through the passageway from the center of the tubing into the next cylinder liquid a motive, the end surface of the piston ring action; at the same time, submersible fuel pump  ,high pressure power fluid into the chamber through the channel b c, d and then by passage into the motive fluid to the cylinder, in the upper surface of the piston. Because the piston, under the effect of the two ends of different sizes to produce pressure, fuel dispensing meters motivated by the liquid pump plunger downward. Piston rod is actually an auxiliary control slide valve on the shaft, the lower part of the control slot opened e and f. When the piston rod near the bottom dead center, the upper control channel e communicate on the master slide valve, the lower chamber c and g, a high-voltage power fluid from the control into the main grooves e of the lower end of the slide valve chamberg. Since the end face of the main spool area under an area larger than the upper end, the role of power fluid under high pressure is generated pressure, cause the main control spool to the top dead center, thereby completing the down stroke.

Peristaltic pump also known as the hose pump

Peristaltic pump also known as the hose pump,which is work through the wheel or squeeze the hose clamps,gas transfer pump peristaltic pump is to rely on a number of rollers alternately squeeze / release pumping effectiveness happen to work along by an elastic tube squeeze occurs when fluid flow output, pipe pressure disappears after relying on its own elastic restitution, repeated as muscle contraction,gear type pump relaxation effects make the blood flow in the veins like. Volume increases, the occurrence of vacuum suction fluids.
Such action shall be continuous peristaltic pump works. The peristaltic hose pump is a peristaltic pump accessories, mainly used to transport liquids, gases, liquids and mixtures of gases and solids. Peristaltic pump hose has a certain elasticity, has some wear, fuel dispensing machine with a certain ability to withstand pressure, no leakage (air tightness), low absorption, temperature resistance, not aging, no swelling, anti-corrosion,low precipitates .
