1. Description
AMR/AMI communication 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 Smart- Metering AMR/AMI Systems.
Typical applications:
■
Wireless remote readout of water meters with
walk-by or drive-by system
■
Radio transmission of the readings to mobile
or stationary receivers
■
Remote reading of the meters via M-Bus
systems
■
Remote reading via GSM module
■
Accurate dosing of fluids in the industrial and
commercial segment
■
Information of the flow volume and consump-
tion e.g. by the means of a pulse couting
module or measuremet transducer
The EDC communication module ensures that in
case of remote transmission of the readings, the
current status always 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 with-
out retroaction on the register. The electronics
detects reverse pulses which will be computed
internally, so that by means of the EDC module
always the current status of the roller counter will
be transmitted and read remotely.
,
The EDC-module is available in four different
versions:
■
RADIO: wireless M-Bus radio module accord-
ing to OMS-Standard (868 MHz), EN 13757-4
■
M-Bus: wired M-Bus-module, EN 13757-3
■
Pulse module: pulse module with forward and
reverse detection
■
M-Bus/Pulse combined M-Bus and pulse
module
The EDC modules are each powered from a bat-
tery, which –depending of the version- has a life-
time of up to 15 years.
Scope of delivery
EDC communication module with installation no-
tice, fixing screw (s), yellow adhesive securing
mark (s) and water meter lid.
