Twin‑Rotor Positive Displacement Flowmeter

Product Overview

The twin‑rotor flowmeter is a positive displacement meter. Two precision helical rotors in the measuring chamber mesh and rotate at the same speed, dividing the fluid into segments of equal volume that are counted to measure flow. Accuracy reaches 0.1% with a turndown ratio of more than 10:1. The rotors never touch each other and are driven by synchronizing gears, giving self‑lubrication, low pressure loss, low noise and vibration, long service life and easy maintenance. Both mechanical direct reading and signal output are supported. It is ideal for demanding metering applications that require high accuracy and robustness.
