High-end vortex flow meter Ordinary vortex flow meter Plug-in vortex flow meter
LUGB type vortex flow meter is widely used in petroleum and chemical industry. Metallurgy, thermal power, textile, paper making and other industries have the effect of superheated steam and saturated steam. Measurement and control of compressed air and general gases (oxygen, nitrogen, hydrogen, natural gas, coal gas, etc.), water and liquids (such as water, gasoline, alcohol, benzene, etc.)
● No moving parts, long-term stability, simple structure, easy to install and maintain
● The output of the sensor is pulse frequency, its frequency is linear with the actual flow of the fluid being measured, the zero point has no drift, the performance is very stable, the structure is very stable, and the structure is diverse. There are pipeline and plug-in flow sensors
● The accuracy is high, usually the measurement accuracy of liquid is ±1.0%; the measurement accuracy of gas is ±1.5%
● The measurement range is wide, and the Reynolds number is within the range of 2*104~7*106, up to 1:20
● The installation method is flexible, according to the different process pipelines on site, it can be installed horizontally, vertically and inclinedly at different angles
● It adopts noise cancellation circuit and anti-vibration sensor head, which has certain anti-environmental vibration performance
● Using ultra-low power consumption single-chip microcomputer technology, one 3V10AH lithium battery can be used for more than 5 years
● The software corrects the non-linearity of the meter coefficient to improve the measurement accuracy
● Use EPROM to protect the accumulated flow from power failure, and the protection time is more than 10 years
