KAL L

Electronic Flow Monitor for air

Method of operation
The model KAL-L-... electronic flow switch monitors air and gas flow flow. It is suited for securely monitoring flows with minimum pressure loss.

Function
The operation of the electronic flow monitor is based on the proven calorimetric principle. A detecting sensor is heated to a few degrees above the temperature of the flow medium Whe the medium flows, the heat generated in the sensor is transferred to the medium, ie, the sensor is cooled. The cooling procedure is a measure of the flow velocity. A second sensor measures the medium temperature. The electronics compares the resistance of both sensors by means of a Wheatstone brige circuit, and switches an output relay if the actual valve drops below the set switching valve.
