CAEtech rain gauges: maximum accuracy up to 800 mm/h intensity

Since 2012, CAE has been among the first companies to equip itself with procedures and facilities to certify all rain gauges within its production in Class A, according to the requirements of the Italian standard which, at the time, regulated the certification of accuracy of rain gauges with special reference to the measurement of rainfall intensity.

Today, following the example of what has already been achieved in Italy, the European standard UNI EN 17277: 2020  was estabished. The different accuracy classes to which the various instruments can be certified remain substantially identical: there still are 3 reference classes which are called A, B and C.

The methods for certifying sensors in the various classes are similar, albeit slightly stricter in the European version. The company is proud to announce that all our rain gauges can be certified in Class A according to the new standard too, where the maximum errors in the measurement of intensity on a 1minute scale are less than or equal to ± 3%.

In the same period, thanks to modifications carried out on the equipment used and the redefinition of test procedures, the actual operating ranges have been verified and extended for all the rain gauges produced by CAEtech, with the relative error values.

The strict tests performed show that the rain gauges of the PG10 line and those of the PG2 line, with a collection surface of 1000 cm² and 200 cm², guarantee a maximum error below 3% of the measurement, up to 800 mm/h and 700 mm/h of rainfall intensity respectively.

The innovative PG4i stand-alone rain gauges, with a collection surface of 400 cm² and resolution up to 0.1 mm, guarantee an error of less than 3% of the measurement up to 350 mm/h of rainfall intensity.

The tests performed have also shown that, since the products are “Made in CAE” and can be customized and selected on request, it will be possible to meet any requests for instruments with even greater range and performance.
