Answer / jazz

Use a smart communicator device such as HART
calibrator/communicator. Connect it across +/- terminals,
whether in the instrument, junction box, marshalling, or
system cabinet, then initiate communication with the smart
transmitter. If you calibrate on-line, the HART communicator
will ask you to put device in manual, and advise control
room that you are calibrating the HART transmitter. Using
the HART communicator use loop/calibrate function and
simulate, 4,12,20 mA corresponding to 0%,50%, 100% of level
or pressure.

dear friends, i have seen flow as the selection critriea in presure guage (bourdon tube) and i would like to know what is the relation between flow and performance of pressure guage other parameters i found in the data sheet are pressure max. 1ksc temperature max. - 50 deg c line size - 80NB operating range - 1ksc pr. guage range - 0-2 ksc thank u,
