More information of CH-LGX wedge flow meter:
Wedge flowmeter is a kind of side-wall contraction type throttling device. The detecting element of wedge flowmeter is wedge, which is a piece of V-shaped throttling member, with its rounded top angle facing downward, so as to facilitate the smooth passage of liquid containing suspended particles or viscous liquid, and will not produce stagnation on the upstream side of the throttling member. Wedge flow sensor and differential pressure transmitter supporting, in the petroleum, chemical, metallurgy, municipal and other fields have a wider range of applications. Especially in mud, sandy crude oil, slurry, residual oil, heavy oil and other fluids containing fixed suspension flow measurement has its unique superiority.
Wedge flow meter
Product features:
(1) a wide range of applicable media, especially suitable for measuring mud, coal tar pitch, coal water suspension and other high viscosity fluids;
(2) can measure corrosive media, due to differential pressure measurement is the use of diaphragm-type double-flange differential pressure transmitter, corrosive media can not enter the guide tube and differential pressure transmitter, so our company uses corrosion-resistant materials to process the wedge-shaped throttle parts, it will enable the instrument to measure the corrosive media.
(3) Reynolds number of a wide range, generally in 300 ≤ ReD ≤ 106; in the case of very low pipeline Reynolds number, when ReD = 300 when the flow rate and differential pressure can still maintain the square root relationship. The orifice plate flowmeter can be measured *** small Reynolds number than the wedge flowmeter is much larger.
(4) simple structure, installation, use and maintenance.
(5) The use of “V” shaped body throttle parts can eliminate the stagnation area, to prevent the system from blocking phenomenon.
(6) Separate wedge flowmeter, can be replaced by the wedge to achieve the purpose of expanding the range or changing the range;
