Product Overview

The Lightweight Oval Gear Flow Meter CH-LC is a positive displacement flow meter designed for accurate measurement of low- to high-viscosity liquids. Featuring a lightweight structure, compact dimensions, and high measurement accuracy, it is widely used in industries including petroleum, chemical processing, pharmaceutical manufacturing, lubrication, and paint production.

The meter adopts a precision oval gear measuring mechanism that delivers stable volumetric flow measurement with excellent repeatability. Its compact construction allows easy installation and does not require an upstream straight pipe section, making it suitable for installations where space is limited.

Working Principle

The CH-LC Series operates using the positive displacement principle. As liquid enters the measuring chamber, a pressure difference is created between the inlet and outlet, causing the precision oval gears to rotate continuously.

During each rotation, a fixed volume of liquid is trapped between the gear teeth and the chamber wall before being discharged to the outlet. The number of gear rotations is directly proportional to the volume of liquid passing through the meter, allowing accurate volumetric flow measurement.

This measuring method provides stable performance and is less affected by changes in liquid viscosity.
