LUX-150S Spiral Vortex Flow Meter

1、 Overview of LUX-150S Spiral Vortex Flow Meter
When the fluid flowing along the axial direction enters the inlet of the LUX-150S vortex flowmeter, the vortex generator forces the fluid to undergo rotational motion, resulting in a vortex flow at the center of the vortex generator. The vortex flow spirals in the Venturi tube and reaches the contraction section where it suddenly throttles, accelerating the vortex flow. When the vortex flow enters the diffusion section, it is forced to undergo a spiral type secondary rotation due to the backflow effect. At this point, the rotational frequency of the vortex flow is proportional to the velocity of the medium and is linear. The weak charge signals detected by two piezoelectric sensors are differentially amplified, filtered, and shaped by a preamplifier into two pulse signals with frequencies proportional to the flow rate. At the same time, the processing circuit compares and distinguishes the phase of the two pulse signals, removes interference signals, and counts and processes the normal flow signal.
