Wedge flow meter is a differential pressure instrument specially designed for the measurement of dirty fluids.
The wedge restriction is V shaped to give better differential for high viscous fluids and for the fluids having low Reynolds numbers.
This instrument can be used for the measurement of slurries, liquids with solid particles, gas and steam. bidirectional flow is possible in wedge flow element.
The manufacturing standards we are following for the design of wedge flow measurement is ANSI, ASME and RW miller.
Wedge meters can be used to measure flow with a minimum Reynolds number of 300 and viscosity upto 3000cP.
