Positive Displacement Flow Series

The intelligent gas Roots flow meter integrates flow, temperature, and pressure sensing with intelligent computation. It features high accuracy, wide rangeability (up to 1:216), low startup flow rate (0.04 m³/h), and low pressure loss. Suitable for metering non-corrosive gases such as natural gas, city gas, propane, nitrogen, etc.

The oval gear flow meter is a high-precision positive displacement meter with an accuracy of ±0.2% to ±0.5% (special up to ±0.1%), unaffected by flow conditions and Reynolds number. It is widely used for precise metering of oil products and chemical solutions in petroleum, chemical, and commercial trade.

LC oval gear flow meter is a positive displacement meter that relies on the pressure head of the medium to drive the oval gears for metering. It features high accuracy, wide range, low pressure loss, and strong viscosity adaptability, making it especially suitable for metering high viscosity liquids (petroleum, chemical, food, pharmaceutical).
