The Series P1 Brass Flow Switch utilizes a piston-type design for accurate detection of excessive or insufficient flow rates.The piston magnetically actuates a hermetically sealed SPDT reed switch. The switches have preset actuation points from 0.10 to 1.5 GPM for liquid flow. The Series P1 is ideal for protecting against loss of fluid flow in hydraulic systems or assuring proper coolant flow in semiconductor processing.
