The UB series inline flow switches are magnetically actuated piston style sensors that switch in response to very low fluid flows. They are ideal for all types of pressure boosting pump control and for the control of commercial or domestic hot and cold water systems.
They find application in monitoring industrial safety showers and in many applications where extreme reliability is paramount. The UB series flow switches are also ideal for constant pressure pump control.
The Metal body of the UB25 flow switch houses a free sliding piston.
Any flow, either pulsed or continuous, causes the piston to be pushed back within the switch body to a point where liquid can pass around it and out of the switch.
When pushed back by flow, the piston actuates a magnetically linked switch.
When flow stops, the piston is pushed back to the off position by magnetic repulsion.
There are no springs in the wet area of the switch, and the magnetically isolated piston provides an exceptionally reliable mechanism.
The UB25 flow switches can be mounted in any orientation including upside down, in either horizontal or vertical pipework.
