Description
The P25 inline flow switch is a rugged versatile all position mounting flow actuated
switch that can detect the flow of liquids in 15mm (1/2″) to 25mm (1″) diameter pipes.
The P25 can be used in larger pipe systems provided the maximum flow does not
exceed 100 litres per minute. The switch can detect very low flows, and yet has a low
head loss, high flow through rating. It can be used to detect continuous or pulsed flows.
The P25 finds a myriad of applications in industrial, rural and domestic pumping
systems. It is particularly well suited to pressure pumps due to its ability to detect and
switch at extremely low flows. In addition the P25 can be used to protect low yield
bore pumps and in tank filling applications. There are no metal parts in contact with
liquids such as groundwater, seawater and in acidic and alkali solutions. The P25 flow
switch is supplied complete with unions and standard PVC pipe sockets for direct
solvent gluing into PVC pipework. The union threads on the P25 are standard parallel
BSP form and where required can be used to secure the switch directly into
threaded Pipe-work.
Applications
- Safety shower alarms
- loss of prime protection for pumps
- Flow monitoring for large dosing systems
- Control of tank filling systems
- Low yield bore pump protection
