The P25 Inline flow switch is a rugged flow actuated sensor that can detect the flow of liquids in 15mm (0.5″) to 40mm (1.5″) diameter pipes. The switch can detect very low flows yet has a low head loss high flow through rating. It can be used to sense either continuous or pulsed flows.
The P25 finds a myriad of applications in industrial, rural and domestic piping systems. It is particularly well suited to pressure boosting applications and in the control of constant pressure pumps, due to its ability to detect and switch at extremely low flows.
In addition the P25 finds application in the protection of low yield bore pumps, and in remote tank filling systems. There are no metal parts in contact with liquids within the switch, so it is ideal for use in aggressive liquids such as groundwater, seawater, acids and in many chemical solutions.
The standard switch is supplied complete with pipe sockets and unions, for direct fitting into PVC, ABS or Poly pipework. The heart of the P25 flow switch is a 500V 20A single pole double throw switch with Tungsten contacts capable of directly controlling single-phase pump motors up to 1.5kW (2hp).
A manual override switch is built into the body of every P25 flow switch. This feature allows pumping systems to be manually activated at any time for normal starting or for priming testing or commissioning.
