Answer Posted / radha
this is called wet leg system,so you are telling range -600
to 0 means your drum distance between HP & LP 600 mm and HP
and LP legs both are filled with condensate(water)
continueosly but LP leg distance higher than the HP leg,so
LP side pressure will acting 600mmWC extra, compare with HP
leg pressure,so we have to eliminate that pressure LP
pressure 600mmWC
thats why -600mmWC = 4mA
0 mmWC = 20mA

Linear amplifier.
A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
