Process Instrumentation : Flow Measurement

Advertisement

Maintaining proper flow of fluids in a process system is essential to maintain correct supply of raw materials to reactors, correct supply of water or steam for cooling or heating purpose etc. Flow meters sense the amount of flow passing through a particular pipe and sends this information to process controller which then applies process logic and sends control information to control valves or pump control unit.

A variety of flow meters are used in process industry depending on type of fluid, operating temperatures and pressures, required flow accuracy and economy. Most of the flow meters require proper flow pattern established in pipe. Flow turbulence can affect accuracy of readings. Hence they have straight pipe requirements without any branches upstream and downstream of them. These are provided by instrument department and instrument vendor. They must be strictly adhered to.

Here is a brief description of all these flow meters sufficient from piping engineering point of view.
