1.Product description
Inductive Clip-on module for water meters
The EDC module (Electronic Data Capture) for non
reactive electronic pulse detection of all ZENNER
water meters whose registers are equipped with
modulator disc is ideally suited for secure remote
reading and integration of water meters in AMR/AMI
Systems.
Intended purpose
Retrofit radio module for water meters for readout
purposes and data transmission to mobile or
stationary receivers.
Scope of supply
EDC module with installation manual,
fixing screw(s),
yellow adhesive securing mark(s),
water meter lid
Typical applications:
■
Wireless remote readout of water meters with
walk-by or drive-by system
■
Wireless remote readout of water meters via
LPWA-networks (LoRaWAN)
■
Radio transmission of the readings to mobile
or stationary receivers
■
Remote meter reading via M-Bus Systems
■
Remote meter reading via GSM module
■
Accurate metering of fluids in the industrial
and commercial segment
■
Indication of flow volume and consumption
e.g. by the means of a pulse couting module or
measurement transducer
The EDC communication module ensures that in
case of remote transmission of the readings, the
current status will be transmitted. There is no replica
of the meter index due to pulse counting. The pulse
detection of the register’s modulator disc occurs
electronically and without retroaction on the reg-
ister. The electronics detects reverse pulses which
will be computed internally, so that by means of the
EDC module the current status of the register will be
transmitted and read remotely.
The EDC module is available in five different ver
-
sions:
■
wireless M-Bus radio module according to
OMS-Standard (868 MHz), EN 13757-4
■
LPWAN-Radio module for LoRaWAN™
■
wired M-Bus-module, EN 13757-3
■
Pulse module with forward and reverse flow
detection
■
combined M-Bus and pulse module
The EDC modules are each powered from a battery,
which - depending of the version - has a lifetime of
up to 15 years (wM-Bus) and 10 years (LoRaWAN
TM
).

The ZENNER EDC modules have been developed
for all ZENNER water meters whose registers are
equipped with AMR/AMI modulator disc (Picture 1).
Depending on the version, the registers are equipped
with 6- or 8-digit roller counters.
