Air flow meter

Wuxi oubai electromagnetic flowmeter is manufactured with the latest technology of contemporary electromagnetic flow and has the following characteristics:
An air flow meter is an apparatus for converting the flow of inhaled air into electrical signals. The advantage of the air flow meter is that the pressure loss is very small, can be measured flow range. Air flow meter maximum flow and the ratio of minimum flow part of above commonly, applicable industry wide range of pipe diameter, and up to 3 m, the output signal and the measured flow into linear, high accuracy, can be measured conductivity of 1 mu s/cm or more acid, alkali, salt solution, water, sewage, corrosive liquid and slurry, pulp fluid flow. But the air flow meter cannot measure the flow of gas, steam and pure water.

Measure the volume flow and mass flow of steam, gas and liquid.
It can realize the disassembly and assembly of the sensor without interruption, and the separation of the amplifier and the sensor (separation distance of 15m).
Using disturbance elimination circuit and anti - vibration sensor head, vortex flow meter makes the meter has a certain anti - environmental vibration performance.
The pressure loss is small, the range is wide, the range is up to 10-40 times.
No mechanical moving parts, long-term stability, simple structure for installation and maintenance.
Pieces can be measured medium temperature up to + 350 ℃ (+ 450 ℃).詳情頁EN_10.jpg
