I. Working Principle
The HNF40-B vortex flowmeter operates based on the von Kármán vortex street principle.
When fluid flows past a bluff body (vortex generator) inside the pipeline, alternating vortices are formed on both sides of the body. The frequency of vortex generation is proportional to the fluid velocity; the sensor detects the vortex signals, and internal signal processing circuitry calculates the fluid flow rate.
As there are no moving parts involved in the measurement process, the vortex flowmeter features a simple structure, low maintenance requirements, and excellent long-term stability, making it suitable for flow measurement across a wide range of industrial media.
