Flocorp CalFlo™ CFSG Flow and Temperature Thermal Mass will monitor flow and temperature to protect equipment and process from high temperatures and no-flow conditions. Offered in general purpose and hazardous proof configurations, this compact flow switch is a great choice for monitoring a diverse range of liquid applications.

The CFSG has NO moving parts and is a reliable alternative to failure prone mechanical flow switches. The short sensor is intended for use in pipe sizes ½” to 1 ½” in diameter and the long sensor is recommended for pipe sizes 2” and up.
