Detection method of vortex frequency of vortex flowmeter

Abstract: The information on the detection method of the vortex frequency of the vortex flowmeter is provided by the excellent manufacturers of flowmeters and flowmeters. Vortex flowmeter There are two main methods for detecting the vortex frequency. Method 1: Detect the flow rate change when the vortex occurs, using thermal elements, ultrasonic beams, etc. The vortex generator can be a solid cylinder, a rectangular column, a triangular column and a T-shaped composite column. square. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of the detection method of vortex frequency of vortex flowmeter. There are two main methods for detecting the vortex frequency of a vortex flowmeter. Method 1: Detect the flow rate change when the vortex occurs, using thermal elements, ultrasonic beams, etc. The vortex generator can be a solid cylinder, a rectangular column, a triangular column and a T-shaped composite column. Method 2: Detect the pressure change when the vortex occurs, using strain elements, piezoelectric elements, vibration magnetic sensors, photoelectric elements, elastic elements/capacitance elements, elastic elements/piezoelectric elements, etc. The vortex generators can be hollow cylinders, triangular columns, T-shaped columns and various composite columns. The thermal detection element has high sensitivity and is suitable for lower temperature (<200℃) and lower density gas measurement, but because the thermistor is encapsulated with glass, it is relatively fragile and easily affected by dirt, harmful substances and particles in the fluid, so the measured medium should also be a clean liquid. or gas. Piezoelectric elements are resistant to dirt, so they are widely used, but they are not suitable for measuring low-density, low-velocity gases and occasions with large environmental vibrations. The medium temperature range is -32～110℃. At normal temperature, piezoelectric ceramics are insulating, and the impedance is l0~l00MΩ, but if working at 300°C, the impedance will drop to 1MΩ, even tens of thousands of ohms, the output signal becomes smaller, resulting in the deterioration of the low-frequency characteristics of the measurement system, so it cannot be used in high-temperature media. The vortex flowmeter has strong vibration resistance, but the temperature of the medium cannot be higher than 200 ℃. If it exceeds this range, the ultrasonic probe will be damaged. The ultrasonic vortex flowmeter cannot be used in the occasions where the measured medium has obvious pulsation, such as the fluid at the outlet of the reciprocating compressor, because it has a high sensitivity to small flow. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Detection Method of Vortex Frequency of Vortex Flow Meter'
