Dear Friend,
The feed water flow transmitter in the HRSG having 0 to 5000mm H20 range and in DCS it is 267.6 T/H. The field transmitter doesn't have a square root in it. The calculations are done by DCS. I want to know do we need to input the range in DCS logic to calculate flow inside DCS? i mean the transmitter giving only 4-20mA to DCS. So the vendor of HRSG says that the Range is not necessary in DCS and need only 4-20 mA to the DCS. Can you advice?
