Application range and wiring requirements of intelligent vortex flowmeter
Vortex flowmeter is based on Karman's vortex street principle research and is mainly applied to flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by low pressure loss, large measuring range, high accuracy, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. Therefore, it is commonly used in petroleum, chemical, electric power, light industry and other industrial pipelines to measure the flow of liquid or gas. It can also be used to measure the flow of fluids in urban water supply, heating, boiler water supply and medical industry. Vortex flowmeter is characterized by no moving mechanical parts, so it has high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The vortex flowmeter uses a piezo-electric stress sensor, which has high reliability and can work in the operating temperature range of -20°C to +250°C. There are analog standard signals and digital pulse signals output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument. Let's talk about the wiring diagram of the vortex flowmeter manufactured by Changzhou Liangbang Meter: LUGB vortex flowmeter local display and two-wire 4~20mA output wiring diagram Physical wiring diagram: Physical installation diagram: Vortex flowmeter and pressure temperature compensation and intelligent flow totalizer wiring diagram: Changzhou Liangbang Instrument Co., Ltd. is located in Tianning Economic Development Zone, Changzhou City, Jiangsu Province. It is close to Shanghai-Nanjing Expressway and Beijing-Shanghai high-speed railway. It is only 30 kilometers away from Changzhou Airport and Yangtze River Terminal.

1. Under normal circumstances, the connection of vortex flowmeter and intelligent flow integrator adopts three-core shielding (RVVP3*0.75mm) shielding layer should be reliably connected to the grounding screw in the amplifier box.
2. The connecting line cannot be discharged together with the power line, at least 50cm apart, and it is best to walk through the metal pipe alone. The connection cable should be fixed and cannot be shaken.
