Series P1 Brass Flow Switch

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series P1 Brass Flow Switches utilizes a piston-type design for accurate detection of excessive or insufficient liquid flow rates.

The switches have preset actuation points from 0.10 to 1.5 GPM for liquid flow.
Features
  • Piston-type operation yields accurate detection of low flow rates
  • The piston magnetically actuates a hermetically sealed SPST reed switch
