Vortex flow meter LXW

volumefor liquidsfor gas and steam

LXW Series vortex flowmeter is manufactured according to the principle of Karman vortex principle together with latest digital transmitter (DSP technology). It is widely used to measure liquid, gas, steam flow in the closed pipeline because the original detection is sealed in the test body, no contact with the measured medium and there is no lining material and moving parting, it does not need on-site maintenance and it is very popular with the majority of users in industries of oil, petrochemical, water/waste water treatment, metallurgy, pharmacy, thermoelectric, etc. for process control and measurement management. Feature And Main Technical Datum *Compact structure *No moving parts, long service time *Long time stability *Same sensor can measure liquid, gas and steam *With acceptable Reynold number, the meter coefficient is free from the influence of the change of temperature, pressure, viscosity and others. *Output Signal: 4~20mA Current(2 Wire System) Or Standard Pulse Output(3 Wire System) Digital Communication Modbus RTU Principle Put a drum vertically into a burette and let some fluid flow down along the drum, by two sides of which there formed, in rotation, regular vortexes , which is called the Karman Vortex Street. An output frequency of the Karman Vortex Street is related to fluid velocity and drum diameter, which can be described by following formula:
