CalFlo™ CFSG Flow and Temperature Thermal Mass, Flocorp-Flow Switch

CalFlo™ CFSG Flow and Temperature Thermal Mass Switch
CalFlo™ CFSG Flow and Temperature Thermal Mass Switch

Featuring single and dual alarm applications, adjustable flow, temperature and flow, air flow, and inline flow, FLO-CORP can provide the appropriate switch for your application. Our switches do not interfere with flow meter accuracy and many can be field adjusted. Plus, when electronics isolation and fail-safe compact relay control are a must-have, we can supply that as well.

The CalFlo series of calorimetric flow switches offers units with several features including temperature & flow, compact relay control, strobe alert, adjustable flow, compact air flow, inline air flow and more. The wide variety of options available enable us to provide the right unit for your specific application. If you need help selecting the correct flow switch, our team is happy to assist in the selection process.

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 CalFlo™ CFSG will monitor flow and temperature to protect equipment and process from high temperatures and no-flow conditions. 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.
