Old flow meter

[Andy Greene]

Is there any reason why I couldnt use another constant source of psi besides propane in and old school flow meter that used propane as long I adjusted my numbers to suite ?

I bought a voltage regulator and vacuum pump off Amazon and converted to battery. Easy and works well.

Voltage regulator setup to use anything at or above 4S lipos and output 11.5 to pump....
