Flow Controls

Control the flow of fluids or air for efficient, reliable, safe equipment operation.

F59 Series

F261 Series

F261 Series flow switches respond to fluid flow in lines carrying water, ethylene

glycol, or other nonhazardous fluids. These models also work in applications with

swimming pool water and lubricating oils. Switches use varied paddle sizes to

respond to fluid flow rates in applications with pipe sizes greater than 1 inch trade

F262 airflow switch

F262 airflow switch detects airflow or its absence, responding to the velocity of air movement in a duct. The single-pole, double-throw (SPDT) control can be wired to open one circuit and close another for signaling or interlock purposes, avoiding overheating, coil icing, or other conditions that may harm air handling equipment.

F263 Series

F263 Series liquid level float switches maintain a liquid level in indoor or outdoor closed tanks that hold water or other nonhazardous liquids. A change in the liquid level causes the single-pole, double-throw (SPDT) switch to close one circuit and open another
