Water Turbine Flow Meter Pulse Sensor Measuring Instrument
The LUGB type vortex flowmeter is a flowmeter designed and manufactured using the Karman principle theory of the relationship between the generation of vortices and the flow rate. It can be used to measure the flow of steam, gas and low viscosity liquids. A triangular column (vortex) generating body is inserted into the fluid, and a regular Karman vortex is formed alternately behind the triangular prism, and the separation frequency of the scoring is proportional to the flow velocity(V) of the measured medium. Therefore, the flow rate of the measured fluid can be calculated by detecting the number of vortices by the flow meter sensor head, and the signal processing circuit calculates the volume flow rate of the measured medium according to the sensor aperture.
1.High accuracy and good repeatability
2.The detection element is not in contact with the fluid, and the performance is stable and the reliability is high.
3.Simple and firm structure, movable parts, reliable operation for a long time
4.Wide measurement range with a range ratio of 1:10 (special up to 15)
5.The pressure loss is small, about 1/4~1/2 of the orifice flowmeter
