LUXQ LUXQ-15 LUXQ-20 LUXQ-25 Vortex flowmeter

Overview

LUXQ LUXQ-15 LUXQ-20 LUXQ-25 Vortex flowmeter is a new generation of intelligent flowmeter that integrates flow, temperature and pressure detection functions, and can automatically compensate for temperature, pressure and compression factor. Chip microcomputer technology and micro-power high-tech, strong function, stable and compact performance, simple operation, the main technology is at the domestic level. The products are widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure the flow of various gases.

Working principle of LUXQ LUXQ-15 LUXQ-20 LUXQ-25 Vortex flowmeter

The flow profile of the flow sensor is similar to the profile of a venture. A set of helical guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent vortex flow. When the fluid enters the diffusion section, the vortex flow is affected by the back-flow and begins to perform secondary rotation, forming a gyroscopic vortex procession phenomenon. The procession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element measures the fluid secondary rotation procession frequency to obtain good linearity in a wide flow range. The signal is amplified, filtered and shaped by the amplifier and converted into a pulse signal proportional to the flow rate, and then sent to the microprocessor together with the detection signals such as temperature and pressure for integration processing, and the measurement results are displayed on the liquid crystal display. (Instantaneous flow, cumulative flow and temperature, pressure data).
