Abstract

The invention discloses a differential pendulum type flowmeter which comprises a base, a slip ring support is detachably connected to the upper portion of the base, the upper portion of the slip ringsupport is fixedly connected with a stator of a slip ring, an acceleration sensor is fixedly arranged in a rotor of the slip ring, and the rotor of the slip ring is fixedly connected with a throttlingelement through a fixedly-connected connecting rod. The throttling element is located below the base, and the sliding ring support and the base are each provided with a sliding groove which allows the corresponding connecting rod to penetrate through and is in sliding fit with the connecting rod. The invention has the beneficial effects that the corresponding flow of the fluid in the pipeline canbe obtained by detecting the swing position of the throttling element, the measurement precision is improved, and the maintenance cost is reduced; due to the adoption of the design without a pressuretapping hole, differential pressure signal fluctuation caused by fluid disturbance by the throttling element is eliminated, and the pressure leading problem of a differential pressure flow sensor applied to a measuring pipeline in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a differential pendulum flowmeter. Background technique [0002] The differential pressure flowmeter has gone through a long development process. It is based on the phase separation or homogeneous model to establish the relationship between the flow rate and the pressure drop. Among them, the throttling differential pressure flowmeter has the longest research history. The methods are basically found in throttling differential pressure flowmeters. The throttling differential pressure flowmeter has the advantages of convenient installation and reliable operation, and has formed a mature international standard in the course of years of research. [0003] The traditional differential pressure flowmeter represented by orifice plate, Venturi tube, bar class, and V-cone has made a very important contribution to gas flow measurement. However, in the process of industrial field use, e...
