Method of operation
The model FEL electronic flow monitor continuously monitors liquid medias. It is suited for securely monitoring flows with minimum pressure loss. Sensitivity to soiling is significantly reduced by means of a single-part sensor.
Theory of operation
The operation of the model FEL electronic flow monitor is based on the calorimetric principle. The sensor is heated to a few degrees above the temperature of the flow medium. When the medium flows, the heat generated in cooled. The sensor signal is compared with the reference data stored in a microcontroller. An alarm signal and/or an analogue signal (4-20mA) that is proportional to the flow velocity is output if the actual flow velocity deviates from the desired flow velocity. The microcontroller allows the flow indicator to be easily calibrated and the temperature to be compensated.
