Hello all,
I have a question about the level transmitter indication.
I have a level transmitter with the type rosemount 1151 GP that is 1 ft above the bottom of the tank.
there is 1.5 ft dead level above the zero of the transmitter. the transmitter gives a level % out put. the range of the transmitter is 0-345'' H2O for a range of 1-41 ft.
The problem is that the level transmitter is giving negative level % output. I have replaced the tramsmitter with new one and insured that it is calibrated, but still getting the negative indication. since the tank outlet is 1.5 ft above the zero of the transmitter, the minimum output should be ~ 3.75 % and not negative. Please advise what to do to get right readings.
