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.
