Product Details

Featuring a switch compartment that’s completely sealed to protect it from liquid, this MCDONNELL & MILLER flow switch has a sensitivity adjusting screw to ease adjustment. Design has an in-line configuration that eliminates the need for a pipe tee. Model is suitable for use in heavy-duty applications where high sensitivity is required, such as cooling systems for bearings, booster pumps, compressors, electronic circuits, water treatment systems, and in other applications where instant switching is required.
