how u measure dp in dp tx? how u calibrate a dp tx?
Answer Posted / amith.patil17@gmail.com
Differential pressure Can be simply measured by DP
transmitter which is connected to the two tapping point
with difference in pressure in both points this DP is
connected after the Threeway manifold valve whose advantage
to calibrate the transmitter on the site by opening the
middle valve so that to get 4mA,else this Pressure change
in level or the flow causes the material dimension change
which material is connected to transmitter which acts as a
resistance to a wheatstone bridge which generates rhe
corresponding current which is transmitted to the control
room.

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,
