The FCS-G1/4A4-AP8X-H1141 is a flow monitoring sensor for liquid media, operating on the calorimetric principle with an integrated processor. It measures flow based on heat dissipation: the sensor is heated slightly above the medium temperature, and as the medium flows, heat is carried away, allowing flow detection. Adjustment via potentiometer, status indicated by LED chain. Protection class IP67.
