Orifice Plate Flowmeters

A very simple and robust solution giving turndown of 4 to 1 and requiring upto 30 diameters straight upstream depending on pipe configuration

An orifice plate installed in a line creates a pressure differential as the fluid flows through it.

This differential pressure is measured via impulse lines by a differential pressure transmitter which converts it into an analogue or digital signal which can be processed to provide a display of the instantaneous rate of flow.

The relationship between the rate of flow and the differential pressure produced is very well understood and is described by the relevant standards BS 1042 and the equivalent ISO 5167.

One of the principle advantages of orifice plates manufactured and installed following these standards is that they do not require calibration. This means that orifice plates are very cost effective on larger line sizes.
