Wedge flowmeter is a new type of throttle differential pressure type, which can perform high-precision flow measurement in the case of fluids with high viscosity and low Reynolds number (reynolds number> 500 can be used); Large-diameter flow measurement occasions have unparalleled advantages and irreplaceable effects.
Wedge flowmeter has the function of correction of parameters such as flow coefficient, non-linear error, temperature change and density change; measurement accuracy can reach 0.5%; it can have on-site display and standard current signal (4 ~ 20mA DC) output, which can be conveniently used Automatic control system or network with computer for automatic adjustment and control of flow or other parameters.
Wedge flowmeter is mainly used for high viscosity (heavy oil, residual oil, diesel, engine oil, etc.), industrial gas (coke oven gas, blast furnace gas, generator gas, city gas), hydrogen, nitrogen, air, water vapor, sewage liquid, etc. Flow measurement of media.
This kind of flowmeter has a simple structure, no moving parts, and is not easy to be abraded by fluids. It has stable, reliable, and long service life. Its measuring element and pressure-receiving device have a special structure, and the fluid does not form stagnation or blockage when passing. Small, ideal for high-precision flow measurement at low Reynolds numbers.
