I have a displacer level transmitter which must work at 4-20ma for 0-400mm level changes.
when I change level from 400mm(at the top of displacer) to 300mm, current will reduce from 20ma to 16ma. when we reduce level more, the current not only reduce but also increase! so we haven't range from 0-300mm.
how can we solve this problem? we have a HART COMMUNICATOR as a calibrator tools.
thank you.
