Rain Gauge Stations & Tipping Bucket Sensors for Real-Time Rainfall Data
Precipitation is the single most important measurement in any flood warning network. Accurate, real-time rainfall data gives emergency managers the earliest possible indication that conditions are developing for dangerous flooding. HydroLynx has manufactured self-reporting rain gauges and packaged rain gauge stations since the earliest days of the ALERT protocol, and our sensors are deployed in flood warning networks across the country.
HydroLynx tipping bucket rain sensors use a precision mechanical design to convert rainfall into discrete digital signals. As water drains through the collection funnel, it fills a calibrated bucket that tips when a precise volume — typically one millimeter — has accumulated. Each tip generates a digital signal that is counted by the data transmitter and reported in real time. The simplicity and reliability of the tipping bucket design has made it the worldwide standard for automated rainfall measurement in operational monitoring networks.
HydroLynx tipping buckets are made of hard anodized aluminum with self-lubricating nylon bearings for long-term reliability. A magnetically operated sealed reed switch provides the digital signal, eliminating the contact corrosion that degrades other switch types. Every HydroLynx tipping bucket sensor carries a lifetime warranty.

Models 2500, 2501, 5050P, 5054TS, and 5045 — tipping bucket sensors and gauge assemblies for integration into custom stations or replacement of existing sensors.
Lexan wind screen that minimizes updraft-induced measurement errors — recommended for all gauges installed in exposed or windy locations.
Accurate rainfall data depends on proper sensor calibration. HydroLynx manufactures the Model 2595 Precipitation Gauge Calibrator — a portable field calibration kit that simplifies both static and dynamic testing of tipping bucket rain gauges. The kit includes a calibrated water bottle, precision dispenser with four interchangeable orifices, and syringes for static tests.
