How to Zero a Pressure Transmitter – Three and Five Valve Manifolds Operation
I had discussed previously on DP Transmitter Valve Manifolds where I explained how to remove a transmitter from active service using 3 and 5 – Valve manifolds but zeroing a transmitter is slightly different.
Zeroing a transmitter involves bringing the transmitter to zero signal but does not remove the transmitter from service.The most popular transmitter manifolds are either a 3 or 5-Valve manifold and the operations involved in zeroing a transmitter using these manifolds are different.
How to Zero a Transmitter with a 3-Valve Manifold
Each step involved will be illustrated with a diagram. It is important to realize that over-pressure or transmitter damage could occur if the steps are not properly followed:
Under normal operation
