Your benefits
- Year-round radio communication:
Readout without access to the premises and freely selectable reading time – interim readings during tenant change possible at any time. - Bidirectional radio communication:
Flexible configuration changes (annual billing date) possible without access to the metering point – no coordination with tenants required. - Comprehensive data protocol:
18 end-of-month and mid-month values available as standard for retrospective utility billing. - Plug and play:
Time savings due to simple and fast on-site installation with automatic start-up (tool-free installation).
Applications
- Efficient readout of heat meters without access to the premises.
- Today “walk-by”, later integrable into a fixed network.
Options
- Extensive log protocol (error codes, tamper and leakage warnings, and backflow notifications)
Properties
- Battery-powered wireless M-Bus radio module
- Radio transmission in the license-free 868 MHz frequency band
- Protection class IP65
- Data transmission via wireless M-Bus according to EN 13757-4
- Simple and fast on-site installation with automatic start detection
- AES128 encrypted radio protocol
- Reliable data acquisition via integrated optoelectronic scanning
(tamper-proof transmission without magnetic or reed switch components) - Migration capable (from mobile readout to fixed network readout)
- Compatible with already installed UPZ +m KOAX, UPZ +m MK, WTZ +m MK, BWZ-V +m, KOAX-FleXX +m and surface-mounted water meters UNIVERSAL EV
- Targeted retrieval of additional data for analysis and evaluation
