After selling millions, our bestseller has been optimised once again and now comes with additional memory for 1,024 daily values. These are compiled as follows: total volume, forward volume, medium temperature, ambient temperature, error status.
We have also raised the security standards. As the first ultrasonic water meter, the HYDRUS 1.3 has the Open Metering Standard - Generation 4, Security Profile B, Mode 7. Each separate data telegram is individually encrypted using session keys. HYDRUS therefore has a future-proof security concept - and is compatible with the German Federal Office for Information Security's Smart Meter Gateway.
Robust construction and the ultrasonic measuring principle make the HYDRUS a high-performer. It is highly precise, reliable and durably cost-effective, even in the harshest environmental conditions. Diehl Metering radio technology, which comes as standard, and a legendary battery life of up to sixteen years make HYDRUS the ideal water meter for automatic reading and smart metering.
The new, compact HYDRUS with a short overall length of DN 20 was developed for economic meter changes in riser and downpipe applications. The HYDRUS family is therefore now even larger and ranges from DN 15 to DN 50 Ask your Diehl Metering contact partner.
