Dwyer P1 Series Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Models are used with oil, air, water and gases. Applications include oil flow control, low flow detection in cooling lines, and high pressure lubrication systems.
Rugged construction and excellent chemical compatibility simplify flow/no flow detection. 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 to 1.5 GPM for liquid flow.
Dwyer P1 Series Features
- Piston-type operation yields accurate detection of low flow rates
- The piston magnetically actuates a hermetically sealed SPST reed switch
- Industrial cleaning equipment
- Detecting loss of fluid in hydraulic systems
- Assuring proper coolant flow in semiconductor processing
