Recalibration/Reranging of Flow DP Tx
Recalibration/Reranging of Flow DP Tx
(OP)
Hi guys.I'm facing a problem with a Flow DP Tx.Currently,the calibration range is 0-850m3/h (0-71kPa).But it gives an over range reading up to 1199m3/h.
The problem is now the process dept wants this tx to be able to read up to 1400m3/h (Changed new pump).The datasheet indicates that the adjustable range of the orifice plate is 112 kPa.Can a recalibration be done to read up to 1400m3/h without changing the orifice plate?

You need to change something. You could change to a higher range transmitter, change the plate, change the piping or change the measurement technology.
