Potter IFS Series Industrial Flow Switch

The Potter IFS Series Industrial Flow Switch is a versatile device designed to monitor and control flow in a variety of liquid applications. It is commonly used to start and stop electrically operated equipment based on flow or no-flow conditions.

The IFS Series is available in several models to meet different application requirements. The IFS-1 and IFS-2 models feature one or two SPDT (Form C) switches, respectively, while the IFS-HC-1 and IFS-HC-2 models offer higher current capacity with their SPDT (Form C) switches. The device is constructed with a durable formed sheet metal enclosure with a powdercoat finish for protection against harsh environments.
