Description
The P26 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 through rating. It can be used to detect continuous or pulsed flows.
The P25 finds a myriad of applications in industrial, rural and domestic pupming 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 pipe-work. The
union threads on the P25 are standard parallel BSP form and where required can be use 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

Description
Flow, or loss of flow detection is a critical part of many scientific and industrial applications. Due to their robust construction and high
sensitivity the CR20 Microflow switches are suitable for detection of loss of flow in a variety of liquid and gas applications. The wetted
parts of the CR20 are made from UPVC with Viton‚ O-ring seals. Optional PVDF versions are also available. There are no metal parts
within the wet area of the switch. The CR20 can be used with a variety of chemical solutions, including most mineral salt solutions,
acids and alkalis. The switch can only be used with clean liquids or gases that are free from suspended solids larger than 20 microns,
and free from particulates or sludge residue that is attracted to magnets. Materials such as Ferric solutions, organic solvents, esters
and keytones in general should not be used with the CR20.
