Spiral vortex flowmeter * does not require special maintenance during operation

　　Spiral vortex flowmeterWhen the fluid along the axial direction enters the inlet of the flowmeter, the rotating blades force the fluid to undergo rotational motion. The bathroom generates a vortex flow at the center of the vortex generator, and the vortex flow rotates in the Venturi tube. When it reaches the contraction section, it suddenly throttles and accelerates the vortex flow. When the vortex suddenly enters the diffusion section, it is forced to undergo a spiral type secondary rotation due to the backflow effect. If the instrument has the most optimized geometric structure inside, then in a wide range, the frequency of the vortex is proportional to the flow rate and linear. The frequency of the vortex in the vortex flowmeter is amplified by a weak electrical signal detected by a piezoelectric sensor, filtered and shaped by a preamplifier, and then becomes a pulse signal proportional to the flow rate, which is sent to the flow integrator for calculation and processing. Processing.
