Page 3: Chapter 1. Introduction
Chapter 1. Introduction Robust, ultra low-power cellular IoT pulse counter and data concentrator (DCU), which comes with a built-in LTE Cat.M, NB-IoT cellular module ensuring reliable data transfer in any environment. The device can be connected to any water meter with a pulse or Mbus output (for water, gas, BTU or any sensor like temperature, optical distance measurement (lidar), etc.).
Page 4 External SMA antenna connector (50 Ohms) Tamper protection (security alarm if cover is tampered) – optional • Cold start (supporting the installation) • Device displacement sensor – activable for PoC • Leak detection, excessive flow/consumption detection (exceeding the normal • consumption, warning of a failure) –...
