Smart Water Meters

Hydrus smart water meters are built on more than 30 years of experience.

They are based on the latest ultrasonic technology and designed to ensure high accuracy and reliability throughout their entire lifetime.

Hydrus Meters were approved by the Ministry of Environment, Water and Agriculture (MEWA) & National Water Company (NWC) in 2011 and more than 1,000,000 meters have already been installed in local water networks.



HYDRUS 2.0 RESIDENTIAL is a static water meter operating on ultrasonic measuring technology. This technology enables accurate calculation of water consumption with long-term stability and eliminates measuring deviations caused by sand, suspended particles, scale or air pockets. Moreover it does not require any earthing.
Developed within the framework of the MID, HYDRUS 2.0 RESIDENTIAL complies with the European regulations and holds sanitary conformity certificates (ACS, WRAS, KTW/W270 and others).
Its integrated radio enables remote reading of the meter’s index and alarms both in mobile (walk-by, drive-by, passive drive-by) and fixed network mode.
HYDRUS 2.0 RESIDENTIAL offers a wide choice of connectivities compatible with the different IZAR reading modes.
A complete Diehl Metering solution is thus available to meet your needs.
