Wedge flow meter is gradually beginning eighties towards a new kind of utility meter, the test piece is a V shaped wedge (also known as wedge-shaped cutting parts), it's smooth vertex down, this will help with suspension particles of liquid or viscous liquids passed, will not be cutting parts in the upstream side of the stagnant production. Therefore particularly suitable in the petroleum and chemical industries for the volume flow and mass flow measurements.
Main features:
1. A good repeatability, high accuracy, by the wedge flow meter calibration, accuracy class 0.5.
2 with self-cleaning ability, no dead zone.
3. wear resistance, long life and high reliability.
4 permanent pressure loss smaller than the orifice.
5 a body structure, on-site installation without the need to install pressure leading pipe, threaded pipe directly or flange connection. Construction of time-saving and easy maintenance.
2 Measuring principle:
Fluid through the wedge flow meter, due to wedge the throttle role in its upstream and downstream side produced a flow rate proportional to the square of the differential, this differential pressure from the wedge to take on both sides of mouth leads, sent to the poor pressure transducer into electrical signals output by the special intelligence via meter operation flow calculation, the flow value can be learned.
