Wedge-shaped flowmeter

产品描述：Wedge-shaped flowmeter is a new type of flowmeter gradually started to practice in the eighties, its detection piece is a V-shaped wedge (also known as the wedge throttling part), its smooth tip Angle is downward, so that it is conducive to the liquid containing suspended particles or viscous liquid through, not in the upstream side of the throttling part stagflation. Therefore, it is especially suitable for the measurement of volume flow and mass flow in petroleum, chemical and other industries...

详细介绍

Suitable for measuring mud, coal tar pitch, coal water suspension and other high viscosity fluids; At very low pipe Reynolds numbers (even as low as Re=500), the square root relationship between flow rate and differential pressure can still be maintained. The minimum Reynolds number of orifice flowmeter is much larger than that of wedge flowmeter. The separately calibrated wedge flowmeter has a high measurement accuracy (up to 0.5%), and the uncalibrated wedge flowmeter has a accuracy of about 3%. Simple structure, easy installation, use and maintenance; Corrosive medium can be measured, because the differential pressure measurement is the use of diaphragm double flange differential pressure transmitter, corrosive medium can not enter the pressure tube and differential pressure transmitter, so as long as the corrosion resistant material processing wedge throttles, can make the instrument to measure corrosive medium.

Product features

■ With good repeatability and high precision, the precision of the calibrated wedge flowmeter can reach 0.5 level.

■ With self-cleaning ability, no stagnation zone.

■ Wear resistance, long life and high reliability.

■ Permanent pressure loss is smaller than orifice plate.

■ One shape structure, no need to install pressure guide pipe, directly connected with pipe thread or flange. Construction time saving and labor saving, convenient maintenance.
