Precession Vortex Flow Meter

Product Description:

HW-LUX Vortex Flow Meter is a collection of flow, temperature, pressure detection function in one, and can automatically compensate the temperature, pressure, compression factor, is the petroleum, chemical, electric power, metallurgy and other industries for gas metering ideal instrument.  HW-LUX precitation vortex flowmeter can be widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flow, is the current oil field and urban natural gas transmission and distribution measurement and trade measurement commonly used products.  Our company's electromagnetic flowmeter, Precession Vortex Flowmeter, Thermal Gas Mass Flowmeter and other products are very high measurement accuracy, balance flowmeter, Nozzle Flowmeter are often used, our products are also very professional.

Working principle ：

The flow profile of the flow sensor is similar to the profile of a Venturi tube.  A set of spiral vane is arranged on the inlet side. When the fluid enters the flow sensor, the vane forces the fluid to produce a violent vortex flow.  When the fluid enters the diffusion section, the vortex flow begins to rotate twice under the action of backflow, forming a gyroscopic vortex precession phenomenon.  The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid, and the detection element can measure the secondary rotational precession frequency of the fluid to obtain good linearity in a wide flow range.  The signal is amplified, filtered, and transformed into a pulse signal proportional to the flow rate by the preamplifier, and then sent to the microprocessor for integration processing together with the temperature, pressure and other detection signals, and the measurement results are displayed on the LCD screen (instantaneous flow, cumulative flow and temperature and pressure data).
