The Lc series elliptical gear flowmeter is our company's leading product. The Lc elliptical gear flowmeter is one of the typical volumetric flow meters used to measure the liquid flow rate that fills the pipeline under a certain pressure. It has the characteristics of simple structure, reliable use, high accuracy, no special requirements for the flow field in the inlet and outlet pipelines, and a wide range of viscosity and flow rate of the measured medium. Therefore, it is widely used for liquid flow detection in industrial and commercial sectors such as petroleum, chemical, pharmaceutical, transportation, and food. The Lc series elliptical gear flowmeter is particularly suitable for measuring oil and fuel.
To meet the needs of the market and different customers, Hefei Jingda Instrument, combined with 60 years of production experience and continuous improvement and innovation, has launched elliptical gear flow meter products suitable for use in different environmental conditions. Remote transmission elliptical gear flowmeter, lightweight elliptical gear flowmeter, high-temperature elliptical gear flowmeter, etc.
