The UHGG 31A G inductive float ball sensor is designed for liquid level detection in boilers and other low‑pressure or open containers. It works with secondary instrumentation to provide water‑level display, high/low limit alarms, and automatic level regulation for safe boiler operation.
The manual details technical parameters, explains the sensing principle, and provides step‑by‑step installation and maintenance instructions, including coil resistance checks, float inspection, and ordering information for spare parts. This manual is written in Chinese.
