Tipping Bucket Rain Gauge

Product Manual

The tipping bucket rain gauge is a professional hydrological and meteorological instrument for measuring natural rainfall. It converts rainfall volume into digital switching signals to meet the demands of data transmission, processing, recording and display.

The core tipping bucket adopts a 3D streamline design, which ensures smooth water dumping performance. It also features self-dust removal capability and is easy to clean.

This rain gauge consists of outer housing, filter, rain collector, funnel, tipping bucket, terminal block, support legs, reed switch and base. The base is fitted with bucket shaft, circular level bubble, reed switch bracket and signal output terminals.

Different from conventional products, its bucket sleeve adopts an integrated positioning structure. The tipping bucket is mounted on bearings via the shaft. All internal components are fully assembled before delivery, requiring no on-site assembly and simplifying field installation.

The tipping bucket features a 3D streamline shape with drooping arc flow guide tips. It boasts elegant appearance, excellent water dumping performance and convenient maintenance.
