Product Details
product details
The best-selling intelligent precession vortex flowmeter adopts the latest micro processing technology, which has the advantages of strong functionality, wide flow range, simple operation and maintenance, and convenient installation and use. Its main technical indicators have reached the advanced level of similar foreign products. Widely used in various gas metering industries such as petroleum, chemical, power, metallurgy, and coal.
Working principle: The flow profile of the flow sensor is similar to the profile of a Venturi tube. Place a set of spiral guide vanes on the inlet side, and when the fluid enters the flow sensor, the guide vanes force the fluid to generate intense vortex flow. When the fluid enters the diffusion section, the vortex flow is subjected to reflux and begins to undergo secondary rotation, forming a gyroscopic vortex precession phenomenon. The precession frequency is directly proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element can obtain good linearity over a wide range of flow rates by measuring the secondary rotational precession frequency of the fluid. The signal is amplified, filtered, and transformed into a pulse signal proportional to the flow rate through a preamplifier, and then sent to the microprocessor for integration processing along with temperature, pressure, and other detection signals. Finally, the measurement results (instantaneous flow rate, cumulative flow rate, and temperature, pressure data) are displayed on the LCD screen.
