The Series P1 Brass Flow Switches utilizes a piston-type design for accurate detection of excessive or insufficient flow rates. The switches have preset actuation points from 0.10 GPM - 1.5 GPM for liquid flow.

• Piston-type operation yields accurate detection of low flow rates
• The piston magnetically actuates a hermetically sealed SPST reed switch
