Diesel oval gear flow meter is a kind of pointer display. The light volumetric flow meter with the cumulative wheel counting device and zero return device is widely used for liquid flow control in various industrial fields. It is suitable for various types of liquid measurement, such as crude oil, diesel oil, and gasoline. With the characteristics of large range, high precision, convenient use and maintenance, and the use of different manufacturing materials, it can meet the needs of liquid flow measurement in various fields such as petroleum, chemical, pharmaceutical, food, metallurgy, electric power, and transportation.
The flow meter consists of a metering box and a pair of oval gears mounted in the metering box. The upper and lower cover plates form a sealed primary lunar cavity (which is not absolutely sealed due to the rotation of the gears) as a unit of calculating the primary displacement. When the liquid to be measured enters the flowmeter through the pipeline, the pair of gears are continuously rotated due to the pressure difference between the inlet and outlet, and the liquid measured by the initial cavity is continuously conveyed to the outlet. The number of rotations of the oval gear and each The product of four times the secondary displacement is the total amount of measured fluid flow.
