A Two-Dimensional Piston Dynamic Flowmeter

Abstract

The invention discloses a two-dimensional piston type dynamic flowmeter. A left metering unit is arranged in the left metering chamber, a right metering unit is arranged in the right metering chamber, and the left metering chamber is fed and discharged through the left metering unit. The right metering chamber is fed and discharged through the right metering unit; the left piston is connected with a left displacement sensor assembly for detecting the axial displacement of the left piston, and the right piston is connected with a right displacement sensor assembly for detecting the axial displacement of the right piston; The displacement sensor assembly and the right displacement sensor assembly are respectively connected to the central processing unit, and the central processing unit receives the left displacement signal sent by the left displacement sensor assembly and the right displacement signal sent by the right displacement sensor assembly, and according to the left displacement signal and the right displacement signal The displacement signal calculates the flow rate; the present invention solves the technical problem that the flow data measured by the volumetric flowmeter in the prior art is discrete and the measurement accuracy is poor, and realizes the real-time reading of the dynamic flow rate with high measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a two-dimensional piston type dynamic flowmeter. Background technique [0002] Positive displacement flowmeter has high measurement accuracy and is less affected by fluid viscosity and flow state. It has been widely used in aerospace ships, mechatronics, chemical engineering and other fields. As a high-precision volumetric flowmeter, piston flowmeter can be divided into rotary piston flowmeter and reciprocating piston flowmeter according to the movement mode of the piston. The reciprocating piston flowmeter has a complex structure and is often used in the refueling mechanism of the gas station. The structure of the rotary piston flowmeter is slightly simple, allowing a certain leakage flow to reduce wear and improve the anti-pollution ability, but sacrifices the measurement accuracy, and can be used for the measurement of liquids such as water and liquid food. [0003] In th...
