Description
The Kelco UB25 Flow Switch is a premium, ultra-sensitive in-line sensor designed for detecting low fluid flows in 25mm (1") pipe systems. Featuring a solid stainless steel body and a magnetically actuated piston, the UB25 offers exceptional durability and performance under extreme conditions. It operates reliably in pressures up to 200 Bar and temperatures up to 90°C, making it ideal for a wide range of applications including pressure boosting, hot water circulation, solar systems, and industrial safety monitoring.
With IP67 weatherproof protection, the UB25 can be mounted in any orientation—even upside down—and its modular electrical design supports SPST, SPDT, or solid-state relay outputs. The piston mechanism, isolated from the electrical circuit by high-power magnets, ensures long service life without springs in the fluid path. Whether for mains boosting, safety shower alarms, or gravity hot water control, the UB25 delivers unmatched sensitivity and rugged dependability.
