VADTel-WM-15
DN 15 mechanical water meter platform with optional telemetry module for residential and light commercial AMR/AMI.
The VADTel-WM-15 is a DN 15 mechanical water meter with a roller register and an optional battery-powered telemetry module for remote reading. It is designed for potable-water metering in residential and light commercial installations that need reliable local measurement and scalable AMR/AMI integration. The telemetry module is an additional functionality without metrological impact: it picks up the register through a pulse interface and transmits readings and events over a cellular network.
Key features
- Mechanical DN 15 meter with a roller register reading directly in m³
- Add-on telemetry module (VAD-UM-01) for remote reading over GSM/GPRS
- Pulse reading interface with a fixed K-factor for telemetry pickup
- Hot- and cold-water variants, with or without telemetry
- Battery-powered telemetry electronics, independent of the metrology
- IP68 meter face and IP65 telemetry cover for outdoor and pit installation
