I am confused in knowing how to configure a DP flow transmitter. What are the basis we use in chossing the range of the DP pressuse in inches of whater and also choosing the range of the output flow. can somebody guide?
You just need the datasheet of the particular transmitter. No need to calculate any range unless if some problem/requirements with the process.
You will get the inches of water column range and output scale in m3/hr (example).
You have to enter the data from the datasheet into the transmitter using HART communicator.
