KH-LUGB series vortex flow meter (air flow meter) Function features: ● air flow meter cost-effective, can be widely applied to a variety of large diameter pipeline gas, liquid, steam flow measurement. ● simple and reliable structure, can achieve continuous stream disassembly. ● pressure loss ● wide range than the range, the range of 10-15 degrees. Air flow meter works: triangular columnar vortex body is provided in the fluid occurs from the vortex of both sides alternately produce a regular vortex, this vortex is called Karman vortex, as shown, the vortex column occur in the vortex downstream of asymmetrically arranged. Air flow meter Advantages: 1, a new generation of intelligent vortex flowmeter, with high precision, anti-vibration, anti-jamming, easy maintenance, suitable for a variety of flow measurement of steam, gases conditions of use. 2, vortex flow sensors and flow indicator and compensation collectively known as vortex flowmeter. It was typical of vortex flowmeter vortex flowmeter. 3, vortex flow sensors is the use of Karman vortex street principle and modern electronic technology and the design and manufacture of a highly reliable, excellent technical performance, good media adaptation and versatility of the new flow meter. KH-LUGB series of air flow meter can accurately measure the gas, liquid and steam flow in effect regardless of physical properties over a wide range of flow rates. Independent of temperature, pressure, and at the same time easy to block, easy card, easy scaling, high temperature, high pressure. Safety explosion-proof for harsh environments. No moving parts, no empty slot design, product no abrasion, dirt, no mechanical maintenance, long service life. High-tech micro-power, battery-powered field display type meter, do not run off more than two years. Compensation regulator integrated design. Current outputs are electrically isolated, with good common-mode interference suppression. At the same time it shows the flow value and cumulative flow value, do not turn switch. Using vibration sensor, the effective elimination of external vibration. Circuit using surface mount technology, compact structure, high reliability. Using split signal converter, cable up to 10 meters. Wide turndown ratio of 20: 1. Instrumentation overall structural design is reasonable, wide dynamic range, low pressure loss. Body made of stainless steel, suitable for aggressive media measurement. Site LCD, pulse, 4-20mA output or 485 can be connected with industrial automation systems.
