Bill, how do you measure fuel?

These guys are using a fuel meter that measures the flow.
I for myself am not all too happy with the thought of having something in the fuel line that can clog up up jam...
A pure voltage "calculator" is not a good solution in my eyes either, because it does not take the fuel system pressure in account (high pressure will lead to high voltage even though there is very little fuel flow)....not critical when uses in a series production turbine, but it will always only work for this manufacturer...me as a homebuilder with different fuel pressures in the various turbines cannot get very far with such a system.
How do you go about measuring the fuel quantity?

Hank
