LUXQ-40 LUXQ-50 LUXQ-65 LUXQ-80 Vortex procession flow meter

Overview of LUXQ-40 LUXQ-50 LUXQ-65 LUXQ-80 Vortex procession flow meter

The fluid entering the flowmeter generates vortex flow through the vortex generator. The vortex flow rotates in the venturi tube and reaches the contraction section. Sudden throttling accelerates the vortex. A piezoelectric sensor is placed in the area where the vortex precession occurs to detect the power frequency of the vortex. This frequency signal is amplified and shaped by the preamplifier and converted into a pulse signal whose frequency is directly proportional to the flow. Finally, it is converted into the cumulative value and instantaneous value of the flow for display through the CPU operation and processing in the intelligent flow integrator. This pulse signal can also be transmitted to secondary instruments such as user computer for calculation and display. It is used to measure the volume flow and total amount of gas in the closed pipeline. It has explosion-proof function and can be used in the environment with explosion risk. It is widely used in industrial and mining enterprises, oil fields, gas fields, metallurgy, electric power, gas and other departments.

Working principle of LUXQ-40 LUXQ-50 LUXQ-65 LUXQ-80 Vortex procession flow meter

The working principle of the precession vortex flowmeter is: when the fluid enters the flow sensor, the guide vane at the inlet forces the axial fluid to rotate and in the constriction section. Due to the accelerated flow of the fluid, a vortex flow is generated in the center of the swirling flow. At this time, with the reduction of the tube carrying area, the vortex flow is concentrated on the central axis. When the vortex flow enters the diffusion section, due to the slowing down of the flow velocity, the rotating fluid is subjected to the action of backflow and begins to do a second rotation, and the vortex flow has a turning point, forming the phenomenon of vortex precession. At this time, the vortex frequency is proportional to the flow velocity of the medium, and is linear. The weak electrical signal detected by the piezoelectric sensor is amplified, filtered, and shaped by the preamplifier and output to the integrator, and processed and calculated to display the pressure, temperature, Instantaneous flow and total volume.
