A future-proofed safety concept

Diehl Metering

HYDRUS is certified according to OMS 4.0.2

Are you looking for a water meter with a future-proofed safety concept? The HYDRUS ultrasonic meter from Diehl Metering has been certified according to the Open Metering Standard - Generation 4, Security Profile B. 

What does this mean in concrete terms?

The Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, BSI) describes in the Technical Guideline "BSI TR-03109" the requirements - e. g. in the area of data security - for water meters in the field of smart metering. The OMS specification 4.0.2 is referred to as the only allowed interface for wireless measuring devices to the BSI Smart Meter Gateway. 

Since January 2017, the Bavarian State Ministry of the Interior, Construction and Transport has expressly recommended that all meters that communicate wirelessly with the Smart Meter Gateway must use the OMS V4.0.2 protocol. Diehl Metering offers you a water meter that meets the high demands of the BSI and the Bavarian State Ministry.  

Useful background knowledge

Ultrasonic water meters not only offer a higher measuring accuracy, but can also provide consumption data - which the supplier needs e. g. for billing purposes - by radio communication. In order to avoid a possible security risk, HYDRUS exclusively uses an encryption procedure certified according to OMS 4.0.2: for each individual data telegram, a key is recalculated and used only once. 

This means that the HYDRUS has a future-proof security concept: it is compatible with the Smart Meter Gateway of the German Federal Office for Information Security (BSI) for maximum data security and can meet 100% of the strict data protection requirements. 

So your customers are well protected!
