The Gill TruMet PW100 is a solid-state, optical rainfall sensor designed to replace the limitations of tipping buckets with a high-precision, low-maintenance alternative.

For decades, rainfall measurement has relied on mechanical tipping bucket gauges. While trusted, these systems are prone to clogging, mechanical drift (requiring frequent calibration for reliable data), and under-counting during high-intensity rainfall, leading to maintenance demands and data uncertainty when accuracy matters most.

The TruMet PW100 uses a solid-state optical measurement principle rather than mechanical collection. LEDs (light-emitting diodes) create a beam of light across a defined sensing area, and a receiver monitors interruptions in the beam caused by rainfall.

By analyzing the size and velocity of droplets, the system accurately measures rainfall accumulation and filters out non-rain interference, such as insects or debris.

With no moving parts, collection funnel, or tipping mechanism, the infrared optical rain gauge delivers accuracy equal to that of traditional tipping buckets, but without the mechanical parts that can fail, reducing maintenance and long-term costs.
