VARIQBLE AREA FLOWMETER: Variable area flowmeters are normally used when local indication only is required.

DIFFERENTIAL PRESSURE/ORIFICE PLATE FLOWMETER: Orifice plats are used in installations where higher pressure drop con be tolerated.


DIFFERENTIAL PRESSURE/ FLOW NOZZLE: Flow nozzles are used in installations where higher velocity and moderately better pressure recovery are required than are obtainable with an orifice plate.

DIFFERENTIAL PRESSURE/ VENTURI TUBE: Venturi tubes are used in installations where high capacity and good pressure recovery are required or where the measured stream contains some solids.

DIFFERENTIAL PRESSURE/ POITOT TUBE, ANNUBAR: Generally, pitot tubes are used in installations where no appreciable pressure drop can be tolerated on high-volume flows, such as on cooling water.


FORCE OR TARGET FLOWMETER: Force or target flow meters measure flow inferentially by measuring the force developed at a disk-shaped target suspended in the flow path. Target meters are used for measuring the flow of viscous hydrocarbon streams.

TURBINE FLOWMETER: Turbine meters measure flow from the rotation produced by the flow past a turbine or propeller. Occasionally, turbine meters are used for process flow measurement where highly accurate, wide range measurement of very small flow rates is required.

POSITIVE DISPLACEMENT: This meter measures flow by isolating, counting, and totaling segments of known volume as they are displaced through its body. Positive displacement meters are used because they are accurate over a wide flow range. They are often used for custodytransfer, particularly for heavy or viscous fluids.


VORTEX FLOWMETER: Vortex meters are oscillatory flowmeters that utilize the vortex train generated by an obstruction placed in a fluid stream. They measure flow by counting the vortices. Vortex meters are used primarily because of their wide rangeability and accuracy. In certain cases, their relatively low cost may also dictate their use.
