The UQK‑A Overflow Observing Annunciator is a compact, marine‑grade liquid monitoring device that integrates visual flow observation and automatic overflow alarm in one unit. Designed primarily for shipboard overflow pipelines, oil tanks, and industrial liquid systems, it provides real‑time visual confirmation of liquid flow while triggering an electrical alarm signal upon overflow, ensuring safe operation and preventing spills.
Featuring a transparent observation window and a built‑in float‑actuated switch, the unit delivers reliable performance under marine and industrial conditions. Its robust construction, standard flange connection, and SPDT alarm output make it easy to install and integrate into control systems. The UQK‑A is widely certified for marine use and suitable for monitoring non‑corrosive liquids with moderate temperature and pressure limits.
