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.
