The product features a stainless steel housing with an IP65 protection rating, offering exceptional durability and superior water- and dust-proof performance. It is self-powered by a built-in lithium battery and accurately calculates all rainfall parameters by detecting the switch‑type (reed‑switch) signals from a tipping‑bucket rain gauge.
The product employs a combined sensing approach using a hydrostatic pressure sensor and a conductivity sensor to monitor water levels. The hydrostatic pressure sensor primarily measures the height of standing water, while the conductivity sensor detects the electrical conductivity of the water and determines whether the water has reached an “immersed” state, thereby achieving equilibrium with atmospheric pressure.

The product employs a dual‑mode measurement system combining radar and hydrostatic sensing. At medium and low water levels, it leverages the radar’s non‑contact ranging capability to measure water level, effectively handling conditions involving water quality, particulates, and floating debris. At high water levels, it automatically switches to a hydrostatic sensor mounted at a higher position, using pressure to sense the water level and thereby addressing the issue of measurements falling into the radar’s blind zone. This composite sensor configuration simultaneously overcomes both the radar’s blind zone and the hydrostatic sensor’s susceptibility to clogging and atmospheric pressure effects, making it one of the most reliable measurement approaches available today. Moreover, the two sensor systems can cross‑calibrate each other, enhancing measurement stability. In particular, it performs exceptionally well in urban manhole‑level monitoring applications.
