Chapter 1. Introduction
The
WM-I3
®
is our 3rd generation low-power cellular pulse signal counter and data
logger with a built-in cellular modem for smart water and gas metering.
Automated water meter readings with customizable breakdowns, leak detection and
prevention. Detection of water leakages to avoid flooding, non-revenue water for
more accurate billing, optimization of operating costs, and improvement of water
supply reliability.
Remote data collection via
pulse input (S0 type)
or
M-bus
(order option) of the
connected meter. Data is sent through
LTE Cat.M / Cat.M
cellular networks to a
central server or HES (Head-end System).
This smart water metering device has a standalone and intermittent operation.
It reads and counts the consumption data (pulse signals or M-Bus data) of the
connected meters in „sleep mode” and saves the data to the local storage. Then it
wakes up at pre-configured intervals to transmit the stored data using
MQTT
or
LwM2M
protocol*, plain TCP/IP packets or
JSON, XML
format.
* Our LwM2M solution is compatible with the Leshan Server, Leshan Bootstrap and
the AV Systems
’s
LwM2M server solution.
