4-20mA Flow Switches

This a thermal type flow sensor, it could detect the air flow precisely. It will not display the flow by percentage % as most thermal flow switch do, it will dispaly a flow speed by m/s, this is a very big advantage than other common thermal flow switch. The position of flange could be changeable to suit any different pipe size

Specification:

* Media: Air or Gas
* Material of sensor: SS316
* Connection: DN15 Flange or Thread
* Output: Standard is 4-20mA, RS-485 0-10V or Relay Limit Alarm is avaialble
* Power Supply: 24V DC
* Measure range: GE-329A 0-10m-20-40-70m/s max; GE-329B 0-10-20-30-40m/s max

Optional Simple Design GE-329B
( Low cost than standard type GE-329A, could be flange or thread connection too)
