The CAEtech PG10 Rain Gauge Has Been Updated

PG10 and PG10R are CAEtech rain gauges with a 1000 cm² collection area. They measure both rainfall intensity and accumulated liquid precipitation and, in the heated version (PG10R), also the water equivalent of solid precipitation, with a final resolution of 0.1 mm.

The measurement error of the PG10 product class is less than 3% up to 800 mm/h and it is certifiable as Class A according to the UNI EN 17277:2020 standard. For this reason, it ranks among the most precise and accurate sensors available on the market for rainfall intensity measurement.

Unlike most used weighing-based sensors, the PG10 delivers this level of accuracy from the very first minute after the detected event, making it particularly suitable for the timely measurement of heavy downpours.

This product is based on patented technology and ensures a high level of innovation and accuracy. It can detect potential malfunctions before they cause interruptions in measurement, thanks to the implementation of diagnostic checks to verify:

• the cleanliness of the funnel that channels water to the tipping buckets;
• the correct levelling of the instrument’s orifice;
• the proper operation of the sensing elements;
• the proper condition of the tipping bucket assembly and moving parts;
• the correct operation of the heating system (PG10R).

The real question is: what has changed? From a firmware perspective, the diagnostic functions and related messages have been redesigned to make them more useful, clear, and user-friendly. Specifically:

1. The status sensor has been refined to provide users with increasingly meaningful, straightforward, and easy-to-understand diagnostics and messages;
2. The operation of the reed switches has been updated to improve data quality in the presence of strong vibrations or wind gusts;
3. In the heated version, the operation of the heating elements has been optimized, making the ring heater unnecessary and improving the instrument’s overall energy balance.

In addition, the production process of these instruments and their components has been revised and, as a result, they now feature a slightly updated design.

“This improvement involves a redesign of the housing, funnel, and tipping bucket materials. This change will allow us to provide an even better service to our customers, in true CAE style, ensuring faster time-to-market, as well as greater standardization and repeatability of components”, says Luca Benati, CAE Operations Director.

The excellent performance that distinguishes the product remains unchanged.
