HYDRUS 2.0 RESIDENTIAL
ULTRASONIC METER
Application
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.
Features
- DN 15 to 40
- MID approval up to R=800
- IP 68
- Wireless M-Bus radio, Wired M-Bus/Pulse/Pulse, Wireless M-Bus radio/L-Bus/Pulse, IZAR BE PULSE compatible, M-Bus, Pulse/Pulse
- Display with alarm codes including leakage detection, radio on and error codes
- Battery lifetime up to 16 years
-
Privacy
The HYDRUS 2.0 RESIDENTIAL saves 512 consumption values with a daily interval. This data can be read locally and accessed only by using the IZAR@MOBILE 2. As a second logging, a small amount of 32 consumption values can be stored. Both the radio protocol and the optical interface are encrypted by default.
