t043 TP/TPUW

Product catalog summary

Description
TP/TPUW rain gauges are high-performance sensors designed to measure rainfall intensity and amount. They utilize a tipping bucket mechanism to ensure accuracy across a range of conditions, with the TPUW version featuring an electronic correction system for enhanced performance during heavy rainfalls. This system adjusts measurements based on rain intensity.

Main Features

Collecting area options: 500 or 1000 cm²
Measurement capability up to 500 mm/h
High accuracy, even in heavy rain
Compliance with WMO & UNI 11452 standards (TPUW version)
Automatic correction system (TPUW version)
Overvoltage protection

Description TP/TPUW rain gauges are very performant and reliable sensors for the measurement of both rainfall intensity and amount. The measuring principle is based on a tipping bucket mechanism, thoroughly designed in order to achieve very high standards of accuracy in the whole range, minimizing friction during the oscillating action of the bucket. The TPUW version is equipped with an electronic correction system to compensate the error caused by the tilting-pan measurement technology, ensuring high levels of performance even when heavy rainfalls occur. The measurement correction is provided...
