Abstract

The invention relates to a torsion target type flowmeter. The torsion target type flowmeter is characterized by consisting of a target sheet (2), a target rod (3), a target torsion pipe (4), a torsion mandrel (41), a supporting ring (42), a torsion rod (61), a regulating spring (62), a strain sensor (63) and a meter head (9), wherein the target torsion pipe (4) is twisted through the after the target rod (3) after target sheet (2) is stressed; and the torsion mandrel (41) drives the torsion rod (61) to rotate to act on the strain sensor (63) to output an electric signal to the meter head (9) to finish transformation. The torsion target type flowmeter is high in structural property and reliable in sealing property; the strain sensor is far away from a high-temperature medium and can be applied to working conditions of high temperature and high pressure; the force measuring range is wide; the target force ranges from one tenth newton to hundreds of newtons; the pressure resistance can reach 42 MPa; and the product has high application ability and wide application range.

Description

technical field [0001] The invention relates to a target flowmeter, in particular to a torque target flowmeter. Background technique [0002] The target flowmeter appeared in the 1960s and is mainly used to solve the flow measurement of high viscosity and low Reynolds number fluids. The target flowmeter is simple and convenient to install, easy to maintain, and the instrument is cost-effective. It is an economical flowmeter. In recent years, the market demand of target flowmeter has been greatly increased, and it is widely used in flow measurement in various fields such as metallurgy, petroleum, chemical industry, energy, food, and environmental protection. [0003] The measurement principle of the target flowmeter is that there is a definite numerical correspondence between the flow of the fluid and the force on the target piece. The formula is as follows: [0004] [0005] q v― Volume flow, α-flow coefficient, γ-stream expansion coefficient, D-pipe inner diameter, d-...
