Abstract

The invention discloses a rolling duplex two-dimensional piston type dynamic flowmeter. A liquid inlet is formed in a left shell, a liquid outlet is formed in a right shell, a left metering unit is arranged in the left shell, a right metering unit is arranged in the right shell, liquid enters and drains from the left shell through the left metering unit, and liquid enters and drains from the right shell through the right metering unit; the left metering unit comprises a left piston, the right metering unit comprises a right piston, and the left piston and the right piston are connected through a rolling type transmission device which allows the left piston and the right piston to keep synchronous rotation and can axially move relatively independently; the left piston is connected with a left speed sensor assembly used for detecting the axial speed of the left piston, and the right piston is connected with a right speed sensor assembly used for detecting the axial speed of the right piston; and a central processing unit calculates the flow according to a left speed signal and a right speed signal. The speed sensor is used for metering the flow, an output signal is in direct proportion to a flow signal, the linearity is high, and the response frequency is high.

Description

Technical field [0001] Technical Field The present invention relates to flowmeters, and particularly to a stack of two-dimensional double rolling piston type flowmeter dynamics. Background technique [0002] High displacement meter accuracy, by fluid viscosity, flow state is small, widely used in aerospace shipbuilding, mechanical and electrical integration, chemical engineering and other fields. Piston displacement flowmeter is used as a high-precision flowmeter, according to the motion of the piston of the rotary piston be divided into a reciprocating piston type flow meter and flow meter. Reciprocating piston flowmeter complex structure, mechanism used in fuel service stations. Rotary piston flowmeter slightly simple structure, allow a certain leakage flow to reduce wear and to enhance the contamination resistance, but at the expense of accuracy of measurement can be used to measure the water, liquid such as liquid food. [0003] Prior art volumetric flowmeter by the rotating ...
