250″wc Orifice plate flow measurement dp transmitter

Request Price

This differential pressure (dp) transmitter can be used to measure the difference in upstream and downstream flowing pressure either side of a orifice plate.

An orifice plate is a physical restriction, typically a plate with a hole in it, that is added inside the flow to create a pressure drop.

The resulting differential pressure measured by the XMD dp transmitter is proportional to the square of the flow velocity according to Bernoulli’s principle.

To produce a linear relationship between the measured dp across the orifice plate and the flow velocity, it is possible to switch the linear output signal to a square root extraction output signal.

It is then possible to convert the SqRt dp to a flow measurement by multiplying it by a constant, derived from other fixed parameters particular to the flow system being measured.
