Oval Gear Flow Meter: High-Precision Positive Displacement Liquid Measurement
The Oval Gear Flow Meter is a light-duty positive displacement flow instrument designed for precise liquid flow control across various industrial applications. It is ideal for measuring a wide range of liquids including crude oil, diesel, and gasoline, offering significant advantages such as a wide measurement range, high accuracy, and ease of use and maintenance.
Working Principle of the Oval Gear Flow Meter
The measurement process begins when fluid enters the flow meter. The pressure difference between the inlet and outlet drives a pair of oval gears to rotate.
As they turn, the fixed crescent-shaped volume between the gears and the housing is sequentially filled and emptied. Each complete rotation discharges a precise, fixed volume of fluid, enabling highly accurate volumetric flow measurement.
