Answer Posted / yugesh shah
Working principle is piezo electricity..
When liquid or vapor passing from vortex meter at that time sensor activate and produce mechanical distoration so at the end emf produces.
In the between of the metal body there is a piezo electric crystal, amplifier in upper side and analog meter in other side...
Both side flange in line of vortex meter
Emf produce and given to amplifier
There is 24v dc to operate an amplifier
Output of amplifier connected with i --> p
Produce 0.2 to 1.0kg/cm2
Given to recorder or controller
Output of controller given to control valve
From that changes in output of controller, valve changes its position as per set point
