I have a site with a differential pressure flow meter that ramps two pumps up and down on a drive. The meter does not seem to be getting a good reading. Both pumps were on at 100% and the meter was only reading 0.8 psi. I was looking the the DX program and noticed that the scaling for the input is setup in the parameter for the input itself. I thought in the GX9100 the scaling for an active input had to be setup in a four line segment? I believe the range is 0-50, but I haven't confirmed the voltage. Has anyone had to setup this type of system before?
