1. Application
The APT-WMBUS-NA-1 is a universal RF (radio frequency) communication module enabling
remote reading of water meters made by Apator Powogaz S.A. The APT-WMBUS-NA-1 counts the
revolutions of a dedicated inductive pointer of the water meter and outputs data via an ISM
868 MHz RF transmitter interface. The dedicated inductive pointer revolutions are detected with an
induction scanning module.

2. Overview
The APT-WMBUS-NA-1 universal RF module (Fig. 1) is a separable module comprising an
interface ring, the RF (induction) module itself and a safety cover for the water meter counter.
The communication unit is an RF module which comprises electronic components, a battery, and
an antenna, which is inside the module’s enclosure to ensure an ingress protection rating of IP68
in the standard version. An optional version is available on request with an extended antenna line
for installation in deep or flooded water meter vaults and other locations which inhibit RF
transmission.
The APT-WMBUS-NA-1 also features an NFC (near-field communication) interface, which is
compliant with ISO 15693 and ISO 18000-3 Mode 1. The APT-WMBUS-NA-1 is mounted on a
compatible water meter with a mounting ring that secures the module properly at the orientation
required (see details further in this Manual).
The APT-WMBUS-NA-1 scans the dedicated inductive pointer of the connected water meter by
detecting the revolutions and their sense with an induction circuit. Induction-based detection
enables remote transmission of water meter counter indications and metering location events over
an ISM 868 MHz RF interface, operating in Wireless M-Bus protocol, providing extensive data
analysis and performance diagnostics.

3. Installation of the universal induction module on water
meters from APATOR POWOGAZ
3.1 Installation prerequisites
Each water meter compatible with the universal induction module features a dedicated
inductive pointer (ref. “Ti” or “Ti/IR” as applicable designations). The water meters can still
be read with the existing module versions (RF modules, pulse modules and M-Bus
modules) which support an optical IR interface.

Prepare the water meter for installation:
Remove the safety cover from the water meter (if installed).
Remove all fouling from the top of the counter mechanism guard (thoroughly clean the ring
recess) and the RF module base which will be directly over the inductive pointer.
Note: Do not use any chemicals, including solvents. Use regular detergents thinned with
water.
Keep the universal induction module in warehouse mode until the installation process.
If preinstalled on a water meter, handle and ship the modules in warehouse mode.
Exit the warehouse mode of the module already installed on the water meter counter.
Alternatively, exit warehouse mode at the installation site; this requires deleting errors
(which include Disconnect Alarm). The installation sequence:
Mount the mounting ring on the water meter counter assembly, choosing the
correct installation orientation.
Mount the module on the mounting ring in the correct installation orientation.
Exit warehouse mode of the module and configure it.
See details further in this Manual.
Install the water meter with the mounted universal induction module near water supply
systems (steel and/or copper piping, other water meters, RF transmission devices,
etc.) and/or electrical wiring respecting the clearances shown in Fig. 5.

3.5 Installing an external antenna
1. Install the external antenna according to its version as shown in Fig. 25.
2. The antenna cable must be secured to fixed parts inside the water meter vault (a pipe
or a wall feature) with standard fasteners (eye bolts, zip ties, etc.).
3. Never secure the antenna or its components (like the antenna cable) to an access
ladder or steps or similar parts which would create a risk of damage.
4. Coil the slack antenna cable length with a diameter above 15 cm and fasten it to a fixed
part near the module. Secure the antenna cable against kinks.
5. When installing in a horizontal orientation, keep the antenna cable bending radius
above 10 cm.
6. Keep the antenna cable at least 15 cm away of all metal parts.
7. The antenna holder must be fastened less than 1 cm from the antenna tip.

4. Operation
4.1 Communicating with the module
The universal RF module features an ISM 868 MHz RF interface for unidirectional communication
T1 and bidirectional communication T2 modes. The data exchange protocol complies with Wireless
M-Bus standards and features a proprietary data frame format. For data communication with the
universal RF module, the Inkasoid app version 1.50.1i or later is recommended with the APT-
VERTI-1 converter available in the Apator Powogaz S.A. product range for walk-by drive-by
collector systems.
The universal RF module also features an NFC (near field communication) interface which is
supported by a dedicated mobile app. The NFC interface is used to exit warehouse mode, reading
historical data and alarm and event details, and more.
4.2 RF interface-based data reading and writing
The universal RF module transmits a spontaneous T1 data frame every 10 seconds between 5:00
and 21:00 and every 60 seconds between 21:00 and 5:00. The data frame contents follow:
Actual water meter indication and actual device date and time;
The last historical water meter indication with its save date and time;
Event flags (see details further in the Manual).
The universal RF module also communicates bidirectionally every third spontaneous data frame in
T1 mode and after every data frame in T2 mode, provided that the automatic bidirectional
communication is not disabled in the configuration.
In the bidirectional T2 mode communication enables data reading and writing in one of four
scenarios: (i) entering or exiting the warehouse mode, (ii) configuration, (iii) deleting or (iv) reading
the detailed data of the module.
Note: All RF data communication with the module is encrypted.
