• Use for alarm notification, flow verification and safety cutoff
• Simple plug-in design for direct control of your chemical feed pump!

Harwil's CF series flow switch controllers do much more than just add a powered control switch to your process. Their simple design with a standard three-prong 120-VAC plug allows use in almost any application—use for basic alarm notification, indication of flow verification, or direct control of chemical feed pumps. Unit can be mounted vertically or horizontally.

CF-8 models feature multiple 120-VAC receptacles in a heavy-duty weatherproof, while-in-use steel electrical box. Single-gang units have one receptacle that's switched, and one that's always energized, providing a convenient power source for instrumentation, lighting, tools, etc. Units allow you to narrow in on flow switch points in the field by placing the included drag discs onto the end of the shaft. Direct process connection; no tee included. CF-8 models feature a 12'L power cord.
