The oil consumption meters are various in types, and can be classified into volumetric oil consumption meters, gravimetric oil consumption meters and various types of fuel flow meters according to the measuring method. The most common fuel consumption meters used today are volumetric fuel consumption meters and gravimetric fuel consumption meters. The automatic oil consumption measuring device adopting the gravimetric method is based on an automatic fuel balance at first, and the most important is the automatic weight transfer method. Later, the device with the structure is further developed into a force balance type fuel consumption meter. The oil charging measurement is changed into the control of an electromagnetic valve, the timing is changed into the control of an electronic counter, the weight addition and subtraction is changed into the control of changing the exciting current of the electromagnetic coil to adjust the size of the balance force, and the balance is changed from an unbalanced state to a balanced state, so that the balance is greatly improved. The existing weight-type fuel consumption meter has the problem of poor precision in the process of detecting the fuel consumption of an automobile.
