Fuel consumption data collection method

1 tank faction ( oil floats )
A typical way is through the installation of buoys in the tank sensor , by monitoring changes in oil level inside the tank to measure vehicle fuel remaining ; or ultrasonic probe to measure the reflection , but the measurement principle no fundamental change in its technical principles decided unable to obtain
proof certification. Another tank itself without legal metrology , does not meet the requirements set volume measurement .
2.ECU faction
ECU measurement method is not actually measured the actual flow through the injector fuel quantity , but  oil equipment  nozzle needle opening time , so once injector on carbon and manganese precipitation, calculate the same nozzle needle open time value , but the actual fuel injection quantity is reduced , which is
leading the main ECU Measurement method not allowed .

Department of Industrial Development Co., Ltd. Shanghai Kang oil on the road in a vehicle retrofit flow sensor, by monitoring the flow of diesel oil in the vehicle to measure the actual fuel consumption engine . This approach is simple in
principle , science, higher  oil expeller  accuracy , more reliable.
Diesel engine with inlet pipe in the structure and return lines . Pump to start pumping oil tank to the power system, high pressure atomized excess oil return to the tank of diesel .Accurate measurement of the oil into the oil and the amount of the difference , is a measure of the actual engine fuel consumption of the scientific method .
