1. What are the advantages of elliptical gear flowmeter products?

1. The measurement accuracy of elliptical gear flowmeter is high, with a basic error of ± 0.5% R, and special ones can reach ± 0.2% R or higher. Special wheel travel is suitable for use on sites that require high-precision measurements.

2、 There is no impact on the measurement accuracy when measuring the velocity field distortion of rotating flow and pipeline obstruction components, and there is no requirement for the front straight pipe section.

3、 Elliptical gear flowmeter can be used for measuring high viscosity fluids with a wide flow range, generally from 10:1 to 5:1, and special ones can reach 30:1 or larger.

4、 It has the ability to directly read the flow rate from the Lechang stool on site, without the need for an external power source, and can measure the cumulative total amount with clear display and easy operation.

2. Structure and principle of elliptical gear flowmeter

The elliptical gear flowmeter consists of a flow transmitter and a counting mechanism, and its working principle is based on the rotation of the elliptical gear to measure fluid flow.

1. The structure of an elliptical gear flowmeter mainly includes two parts: a flow transmitter and a counting mechanism. Flow transmitter measurement room: The measurement room is equipped with a pair of elliptical gear rotors, which together with the cover plate form a crescent shaped cavity, which serves as the unit of measurement for flow. Sealed coupling: The sealed coupling is used to transmit the rotational motion of the elliptical gear to the counting mechanism while ensuring the sealing of the measuring chamber. Counting mecha

nism deceleration mechanism: used to slow down the rotational speed of elliptical gears for more accurate counting. Adjustment mechanism: used to adjust the sensitivity of the counting mechanism to ensure the accuracy of measurement. Counter: used to record and display the total amount of fluid passing through the flowmeter. Messenger: used to convert traffic signals into electrical signals for remote monitoring and automatic control. In addition, for use in high-temperature environments, a heat sink can be installed between the transmitter and the counting mechanism to form a high-temperature flowmeter. The working principle of the elliptical gear flowmeter is based on the rotation of the elliptical gear to measure fluid flow. The pressure difference drives the elliptical gear to rotate by the pressure difference between the inlet and outlet of the flowmeter. When fluid flows in from the inlet, it drives the elliptical gear to rotate and squeezes the fluid out of the lunar cavity, ultimately flowing out through the outlet. During each revolution of the measurement process, the elliptical gear will completely squeeze out the fluid in the lunar cavity and measure new fluid entering the cavity. Due to the fixed volume of the lunar cavity, the fluid volume measured per revolution is also fixed. In fact, the volume of liquid flowing through each rotation of the jujube row is four times the volume of the initial lunar cavity, because the elliptical gear will experience four different positions during rotation, and each position will squeeze out a part of the fluid from the cavity. The rotational motion of the elliptical gear for signal transmission and counting is transmitted to the counting mechanism through a sealed couplin
