Stainless Steel Double Tipping Bucket Rain Gauge
The stainless steel rain gauge is the recognized standard for measuring rainfall and other precipitation in hydrological and environmental testing.The internal tipping bucket structure provides high accuracy in various rainfall intensity ranges. According to different materials, we have three types of tipping bucket rain gauge: all stainless steel rain gauge, semi-stainless steel rain gauge, and ABS plastic rain guage.

How does a double tipping bucket stainless steel rain gauge work?
The double tipping bucket rain gauge operates by counting the number of times the tipping bucket falls. This device is made of stainless steel and divided into two half-cone chambers of equal volume, separated by a partition. It features a mechanical bistable structure.
As one chamber receives water, the other remains on standby. During rainfall, rainwater collected by the receiving port enters the metering bucket via the funnel. When the volume of collected rainwater reaches 0.2mm, the chamber overturns due to gravity, and the other chamber begins to receive water. Upon reaching the predetermined volume, the bucket overturns once more.
Additionally, magnetic steel is installed on the sidewall of the tipping bucket. As the bucket flips, it scans the side of the dry reed tube, turning it on and off. Each time the tipping bucket overturns, the dry reed tube switches on and sends out a pulse or 485 signal
