LGJ vortex flowmeter is a new type of flowmeter introduced by our company. It is a velocity flow meter with a wide range of uses. It is suitable for flow measurement of liquid, steam and most gases. This product has reasonable structure design, powerful functions, and its linear correction function reaches the world’s leading level. When measuring volume flow under working conditions, it is hardly affected by fluid density, pressure, temperature, viscosity and other parameters. There are no movable mechanical parts inside the pipeline, high reliability, low maintenance, and long-term stability of instrument parameters; instrument set signal transmission It is integrated with integrated display, compatible with multiple signal output methods, and is convenient for systematic integration applications. It is widely used in the production process, measurement, control and measurement of oil fields, industrial and mining enterprises, and is especially suitable for the flow measurement of clean water and sewage in oil field water injection stations and water injection wellheads. This product has applied for national patents, patent numbers: ZL 201120419026.1, ZL 201120418875.5, ZL 201420781825.7.
