HYDRUS 2.0 BULK

HYDRUS 2.0 BULK

ULTRASONIC METER

HYDRUS 2.0 BULK 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 BULK 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 BULK 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.

The HYDRUS 2.0 BULK saves 512 consumption values daily . This data can be read locally and accessed only by using the IZAR@MOBILE 2. As a second logging, a small amount of 32 monthly consumption values can be stored. Both the radio protocol and the optical interface are encrypted by default.
