Hello Dear first check the Calibration Range of Transmitter,
Range should be -xxx(495) to 0 mmwc. for 0 mmwc 20 mA will
be come.when you fill the water in condensate pot 4mA wii
be come because it's closed vessels

Dear haider
your transmitter calibration is perfect before charging the tramsmitter you have to fill the water in the condensing pot at low side of the tranmitter
boiler is shutdown condition please confirm DRUM VENT ISOLATION VALVES ARE OPEN
IF DRUM VENT ISOLATION VALVES ARE CLOSE YOU WILL NOT GET CORRECT READING

U have to apply WET LEg method for Differental Pressure
type level mesurmetnt.Keep ur wet leg(Lo side of tx always
filled with condensed water.
Put the range in tx.-19.5 inches of WC to 0 inches of WC.
see the result but make sure that ur wet leg should always
filled with water.otherwise ur tx l go to saturation and

How 2 calibrate level tank having large height..?
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?
