I am doing some research on electric fuel pumps and I would like to determine the RPM. The motor is enclosed so none of the rotating parts are readily accessible. I have a test bench with a variable voltage DC power supply, back pressure control, and appropriate test fluid so the pumps are...
I have a fuel pump tester with a power supply that has a sense circuit for automatic voltage compensation. The power output is controlled by a remote switch to the power supply so there is no switch in the main circuit itself. My problem is that the sense circuit cannot be connected to the pump...
