Hardware sugestion for Diesel flowmeter

[elmaniak]

Hello guys, im planning to implement a sistem for a diesel usage control, is there any hardware you would recommend for this task?

1) Turbine meters were invented specifically to measure fuel flow with high accuracy. Outside of clean, self lubricating fluids like fuels, turbine meters have somewhat limited application.

2) There are coriolis flow meters that will happily measure fuel flow and report it either in mass units or volumetric units.

3) Positive displacement flow meters

4) There might be a thermal dispersion mass flow meter that measures fuel flow in whatever your flow range is, but you should be aware that the technology of thermal dispersion lends itself more readily to gas mass flow measurements than liquid mass flow. Look carefully at flow rates and fluid temperature limits.

Most of these use a pulse/frequency output or an analog 4-20mA signal and 24Vdc power. The spec sheet is your friend.
