RVG series G gas waist wheel flowmeterDetailed product description：

The RVG series G-type gas waist wheel flowmeter, like membrane gas meters and gas turbine flowmeters, is also an instrument for accurately measuring gas flow. The instrument is based on the principle of volumetric measurement and is characterized by high accuracy, compact and sturdy structure, no need for a straight pipe section at the inlet, long service life, and is suitable for installation in narrow environments to accurately measure gas flow rates with large load fluctuations under harsh climatic conditions. The RVG waist wheel flowmeter is specially designed with extremely low pressure loss and a wide range of bits. Measurable media include natural gas, city gas, alkane based gas, and various industrial inert gases. The RVG series instruments are also widely used as standard gauges.
