How does Air Velocity Flow Transmitter Work?
Principle, selection and application of air volume transmitter
Flow rate is the total volume of air passing through the cross section per unit time. The average velocity of the cross section multiplied by the cross-sectional area gives an accurate unit wind volume. However, the average wind speed on the section is difficult to measure, which is related to the medium of the fluid, atmospheric pressure and the roughness of the pipe wall. The maximum value is several times different from the minimum value, and the distribution is uneven. Therefore, the unit wind volume can be calculated by measuring the wind speed at a certain point times the cross-sectional area, with a large error. The selection, installation and application of the air volume transmitter are more like a specific project, the selection is not reasonable, the cost is high, and the result is very poor precision.
The ge-374 air volume transmitter is an ideal choice for ventilation measurement. Its working principle is to measure the fluid pressure in the pipe through the s-type pitot tube. The velocity formula can be used to calculate the fluid velocity in the pipe. The wind speed transmitter depends on the physical characteristics of the s-type pitot tube. So it's not afraid of pollution, corrosion. High stability and low maintenance cost.
The wind speed transmitter is compact in size and can be installed in a narrow space. The performance of the ge-374 wind speed sensor is extremely stable, with a normal life of at least 5 years. Now the latest explosion-proof series is launched, providing the certificate of henan nanyang explosion-proof research institute and the ATEX explosion-proof certificate provided by Hong Kong quality certification center.
Main applications of the ge-374 wind speed sensor: environmental measurement, air transmission, ventilation wind speed, clean rooms, air balance, fan/motor/blower, blast furnace speed, refrigerator, paint shop
The research and development, production and testing of the ge-374 wind speed sensor strictly follow the ISO9001 quality system certification. We have been awarded the ISO9001 quality certification certificate and ISO14001 environmental protection system certificate by the Hong Kong quality assurance center for many years.
