The flow profile of the flow sensor is similar to the profile of a Venturi tube. A set of spiral guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent vortex flow. When the fluid enters the diffusion section, the vortex flow is affected by the backflow and starts to make a second rotation, forming a gyroscopic vortex precession phenomenon. The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The second rotation precession frequency of the fluid measured by the detection element can obtain good linearity in a wide flow rate range. The signal is amplified by the preamplifier. Filtering and shaping are converted into pulse signals proportional to the flow rate, and then sent to the microprocessor together with the temperature, pressure and other detection signals for integration processing, and finally the measurement results (instantaneous flow rate, cumulative flow rate) are displayed on the LCD screen. And temperature and pressure data)
