LC Oval Gear Flow Meter: Comprehensive Product Guide
Introduction to LC Oval Gear Flow Meter
The LC Oval Gear Flow Meter is a high-precision volumetric flow meter designed for accurate measurement of liquids across a variety of industrial and commercial applications. Utilizing oval gear technology, it measures flow by the displacement of fluid between rotating gears, delivering precise, reliable, and repeatable readings regardless of fluid viscosity or temperature.
Widely used in fuel distribution, chemical processing, lubrication systems, and high-viscosity liquid transfer, the LC Oval Gear Flow Meter offers a combination of durability, accuracy, and ease of maintenance. Its robust construction and global compliance standards make it a trusted solution for businesses seeking dependable flow measurement solutions.
Working Principle of LC Oval Gear Flow Meter
The meter operates on a positive displacement principle. The internal oval gears rotate as fluid passes through the chamber, creating a known volume per rotation. Sensors detect the rotation of the gears and convert it into an electronic or mechanical output that corresponds to the fluid flow rate.
Advantages of oval gear technology include:
High accuracy even with viscous liquids
Minimal sensitivity to fluid density and temperature changes
Reliable measurement at low and high flow rates
Compact and robust design suitable for industrial environments
