I. Product Principle
The flow section of the flow sensor is similar to the profile of a Venturi tube. A set of spiral guide vanes is placed on the inlet side. As the fluid enters the flow sensor, the guide vanes force the fluid to generate intense swirling. When the fluid enters the diffuser section, the swirling is affected by backflow, initiating a secondary rotation and forming a gyroscopic swirling motion. This precession frequency is proportional to the flow rate and is unaffected by the physical properties and density of the fluid. By measuring the precession frequency of the fluid's secondary rotation, a good linearity can be achieved over a wide range of flow rates. The signal is amplified, filtered, and shaped into a pulse signal proportional to the flow velocity by a preamplifier, and then sent to a microprocessor along with temperature, pressure, and other detection signals for accumulation processing. The measurement results (instantaneous flow rate, cumulative flow rate, and temperature, pressure data) are displayed on the LCD screen.
