DESCRIBE

The flow profile of the incoming vortex flow sensor is similar to the pattern of the venturi tube. A set of spiral guide blades are placed on the inlet side, which force the fluid to violently vortex flow when the fluid enters into the flow sensor. When the fluid enters the diffusion section, the vortex current is subjected to the reflux and begins to make a secondary rotation to forming The phenomenon of gyroscopic vortex precitation. The precession frequency is proportional to the flow rate size, and is not affected by the fluid physical properties and density. The detection element measures the fluid 2 The subrotation precession frequency achieves good linearity in a wide flow range. The signal is amplified, filtered, and shaped by the preamplifier and converted into a pulse signal proportional to the flow rate, and then sent to the microprocessor for calculation together with the detection signals such as temperature and pressure. Finally, the measurement results (instantaneous flow, cumulative flow and temperature and pressure data) are displayed on the LCD screen. The flowmeter structure is compact, mainly composed of shell, vortex generator, sensor (temperature, pressure, flow), rectifier, bracket and converter. Advance vortex gas flowmeter use conditions ambient temperature: -30℃ ~ + 55℃ relative humidity: 5%~95% medium temperature: -30℃ ~ + 80℃ atmospheric pressure: 86 kPa ~ 106 kPa
