Description
Oval gear flowmeter (also known as displacement flowmeter, gear flowmeter) is a type of volumetric flowmeter, which is a type of flow meter with higher accuracy. It uses mechanical measuring elements to continuously divide the fluid into a single known volume part, and measure the total flow volume based on the number of times the metering chamber is filled and discharged with the fluid in this volume part successively and repeatedly. Oval gear flow meters can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel) and are suitable for flow measurement in industrial sectors such as chemical industry, petroleum, medicine, electric power, metallurgy and food.
The flow meter is composed of a metering box and a pair of elliptical gears installed in the metering box. It forms a sealed crescent-shaped cavity with the upper and lower cover plates (it is not relatively sealed due to the rotation of the gears) as the calculation unit for primary displacement.
When the liquid to be measured enters the flow meter through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, continuously transporting the measured liquid through the crescent-shaped cavity to the outlet. The number of revolutions of the elliptical gear is related to each The product of four times the secondary displacement is the total amount of liquid flow measured (see the figure for the principle). The flow meter is mainly composed of a housing, a counter, an elliptical gear and a coupling (magnetic coupling and axial coupling).
