Product Description Spiral vortex flowmeterSpiral vortex flowmeter adopts the latest microprocessing technology, which has the advantages of strong functionality, wide flow range, simple operation and maintenance, and easy 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 principleThe flow profile of a flow sensor is similar to the profile of a Venturi tube. Place a set of spiral guide vanes on the inlet side, which force the fluid to generate intense vortex flow when it enters the flow sensor. When the fluid enters the diffusion section, the vortex flow is subjected to backflow 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. By measuring the secondary rotation precession frequency of the fluid with the detection element, good linearity can be obtained over a wide range of flow rates. The signal is amplified, filtered, and shaped by a preamplifier into a pulse signal proportional to the flow rate, 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, temperature, pressure data) are displayed on the LCD screen.Flow meter structureThe spiral vortex flowmeter has a compact structure and is mainly composed of a housing, a vortex generator, sensors (temperature, pressure, flow rate), a rectifier, a bracket, and a converter.Conditions for use of spiral vortex gas flowmeterEnvironmental temperature:- 30oC~+55oCRelative humidity: 5%~95%Medium temperature:- 30oC~+80oCAtmospheric pressure: 86kPa~106kPamain features 1.
