Introduction:
The flow profile of the flow sensor is similar to the profile of a venturi. A group of helical guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes
Forces the fluid to create a violent vortex. When the fluid enters the diffusion section, the vortex flow is affected by the backflow and begins to rotate twice, forming a gyroscopic vortex precession phenomenon.
elephant. The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element can measure the fluid secondary rotation precession frequency within a wider range.
Good linearity is obtained in the 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 further correlated with temperature,
The pressure and other detection signals are sent to the microprocessor for integration processing, and finally the measurement results (instantaneous flow, cumulative flow and temperature,
pressure data).
Features:
1. No mechanical moving parts, not easy to corrode, stable and reliable, long life, long-term operation without special maintenance;
2. Using 16-bit computer chip, high integration, small size, good performance, and strong overall function;
