1. Working principle of vortex flowmeter?
Vortex flowmeter (also known as vortex flowmeter) is an extremely versatile flow measurement instrument that can be used for almost all gas, liquid, and steam flow measurement, measurement, and control. The WRLUGB series vortex flowmeter is a new type of flowmeter developed based on the principle of fluid vibration, widely used in the measurement of fluids in industries such as Shifan rubber oil, chemical, metallurgical, and paper wastewater treatment. This flowmeter has no movable parts, strong reliability, high accuracy, and long service life, and can accurately measure the instantaneous flow rate and cumulative flow rate of liquids over a wide flow range. It is not affected by the temperature, pressure, viscosity, and composition of the medium, and is not blocked, stuck, easy to scale, resistant to high temperature and high pressure, safe and explosion-proof, suitable for harsh environments. Flow scoring integrated display and remote transmission display, and can output pulse signals or current signals to connect with microcomputers. Vortex flowmeters are widely used in industries such as petroleum, chemical, light industry, and power heating. Flow meters have the following characteristics: high measurement accuracy and wide range; The measurement medium is wide, such as Zheng can measure liquids, gases, and vapors; The working temperature is high, and the medium temperature can reach 350 ℃; No moving parts, no wear and tear, high reliability; The body is made of stainless steel material, which is beautiful and corrosion-resistant. Working principle: When the fluid medium in the pipeline passes through the vortex generator (triangular column), a vortex phenomenon i
In equation (1), f - the release frequency of the Karman vortex street St - Strouhal number V - the medium flow velocity d - the width of the triangular column Strouhal number is an important parameter of the vortex flowmeter, which is only related to the Reynolds number Re of the medium. As long as the Reynolds number of the medium inside the pipeline remains within the range of 2 × 104 to 7 × 106, the Strouhal number St remains constant. This allows the flow velocity of the fluid medium to be detected by measuring the vortex frequency signal, and then the flow rate of the medium can be calculated based on the flow velocity of the medium.
2. What is an explosion-proof vortex flowmeter?
Explosion proof LUGB vortex flow sensor adopts intrinsic safety explosion-proof technology. The explosion-proof mark of the battery powered vortex flow sensor is "Exia Ⅱ BT4", which is suitable for use in hazardous areas with T1~T4 groups in Zone 0, Zone 1, and Zone 2, which are not higher than Class II B level; The explosion-proof mark of the vortex flow sensor powered by safety barriers is "Exia Ⅱ BT5", which is suitable for use in hazardous areas of Class II, Class B, Zone 0, Zone 1, and Zone 2 containing groups T1 to T5. Characteristics: (1) Simple structure,
