Problems solved by technology

[0003] In actual use, because the impurities in the measured fluid will be adsorbed on the surface of the throttling piece or the throttling piece is corrosive to the measured fluid, the throttling piece will lose its ideal shape, resulting in inaccurate measurement. In the measurement pipeline, its shape change is not easy to be found in time

Abstract

According to the novel balance channel flow meter, through structural improvement, impurity deposition or abrasion on the surface of a throttling element can be found in time, impurities on the surface of the throttling element can be removed or a worker can be reminded to replace the throttling element, the throttling element is kept in an ideal shape all the time, and therefore metering accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to a novel balance channel flowmeter. Background technique [0002] The channel flowmeter is a differential pressure flowmeter. Its working principle is the same as that of the orifice flowmeter. They are based on the fluid continuity equation and the Bernoulli equation. The sensor is mainly composed of a meter body, a throttle, a fixed support piece, It is composed of a pressure induction tube and a temperature installation accessory. The throttling piece has a long enough equal-diameter section at an appropriate position in the middle, forming a uniform loop with the inner wall of the measuring tube. The measured fluid enters the sensor first through the throttling piece. , and then enter the annular channel, forcing the fluid to pass through the ring formed between the baffle and the inner wall of the pipe, the boundary layers on both sides of the fluid...
