Overview
Product Overview
The gas Roots flow meter is a high-accuracy, high-reliability, wide-range gas monitoring and metering instrument. The intelligent gas Roots flow meter integrates flow, temperature, and pressure sensors with intelligent instrumentation on the basis of the Roots flow meter. It is an ideal instrument for measuring non-corrosive gases such as natural gas, city gas, propane, nitrogen, and industrial inert gases.
Performance Features
Wide rangeability (up to 1:216), low startup flow rate (lowest 0.04 m³/h), high accuracy and repeatability, long-term accuracy unaffected by media, low pressure loss, and reliable operation.
