Air Flow Velocity Meter

GE-374 Air Flow Velocity Transmitter is designed for air velocity measuring, monitoring and controlling. Air Flow Velocity Measurement Meter can meet the most air flow measurement condition in the field of HVAC and energy saving. insensitive to dust and dirt, very easy to install and maintain.

Different Structure of the GE-374 Air Flow Velocity Transmitter, LCD screen display is optional

This air velocity sensors are ideal for applications requiring accurate ventilation control. They operate on an innovative hot film anemometer principle. This thin film sensor guarantees accuracy at low air velocity, which is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors. The sensor is also much more insensitive to dust and dirt than all other anemometer principles. It delivers high reliability and low maintenance costs. The configuration equipment allows air velocity adjustment of the sensor. The measuring range and the response time can be selected via jumpers by the user. This facilitates easy adjustment to the correct working range upon startup.

It have same function and structure as Kobold KAH series Air Velocity Sensor, but our products will be much cheap, much more choice. so it will be a good replacement of Kobold KAH series Air Flow Velocity Transmitter.
