Dwyer Instruments P2-17 | Flow switch for gases | Actuation set point 2.5 CFM (70.8 LPM) @ 5 psi.
For use in air or pure water applications, the piston-type architecture of the small Series P2 Model P2-17 Flow Switch is employed. The preset actuation points of the switches range from 0.05 to 1.0 GPM for water and from 25 CFH to 5 CFM for air. There is a hermetically sealed SPST magnetic reed switch included into the piston design. The P2 is made up of 316 Stainless Steel spring and stop pin, PPE & PS (polyphenylene ether and polystyrene) housing and piston. Every part that is moist is FDA compliant. This switch is a great option for heat exchangers, cooling applications, filter life monitoring, and pure water equipment due to its outstanding design and affordability.
