and people.
It is recommended to comply with all applicable safety and accident prevention laws.
Follow nationwide regulations regarding water measurement.
Follow the technical requirements relating to the installation of electrical equipment.
The instrument complies with the requirements of the European Council Directive 2014/30/
EU on electromagnetic compatibility, the Directive 2014/35/EU on electrical safety and the RED
Directive 2014/53/EU.
The warranty and correct functioning are void if the identication plate and seals applied to the
instrument are removed or damaged.
It is forbidden to transport instruments with an active radio interface by air.
To clean the instrument externally, use a soft cloth moistened with water. Do not wash with high

environmental regulations in force.

IWM-TX5 4User Manual v1.2
Do not damage the device casing. In case of impact with external objects, the device can be
irreparably damaged and lose the IP65 degree of protection. Install in areas protected against
impact. In case of breakage of the protective casing, contact customer support.
Pay attention to sharp or edgy protrusions in threads, anges and measuring tubes. In this
regard, it is recommended to wear protective gloves.
Do not expose the instrument to sunlight and other heat sources. Do not throw in the re.
The device must be used in a way that minimizes the potential for human contact during normal
operation. In order to avoid the possibility of exceeding the RF exposure limits, human proximity
to receivers with an integrated antenna should not be less than 20 cm (8 inches) during normal
operation.
Keep out of the reach of children.
The device does not require special protection against electrical interference; however,
electromagnetic interference must be avoided.
If transmission network interfaces are used, especially when cables are routed outside the
building, use increased protection against electrical interference.
The device may only be installed in frost-free areas.

INSTALLATION
The installation of the IWM-TX5 module is allowed on the GSD8-I meters only.
It is recommended to install the IWM-TX5 module away from metal objects or any potential radio shielding, in
a place protected from tampering.
The device could be congured by using the BMetering NFC Cong App. The installer has the task of checking
the propagation conditions of the radio signal during installation.

OPERATING MODES - RADIO ACTIVATION
Once the module is installed, the radio transmission is activated automatically, after that 5 liters of water have
passed through the meter.
It is possible to force the activation and deactivation of radio transmission through the NFC app.
RADIO PARAMETERS
Wireless M-BUS compatible
As soon as the radio operating mode is activated, the device sends a radio telegram according to Wireless
M-BUS, T1 mode (one-way transmission).
Precongured radio parameters
Walk-by mode:
• Transmission frequency: every 60 seconds.
• Transmission interval: 5/7 days (no weekend), every month
• Encryption: disabled (default)
• 12 monthly historical data
• No sending of internal date and time
AMR mode (Default):
• Transmission frequency: every 200 seconds
• Transmission interval: 7/7 days, every month
• Encryption: disabled (default)
• No historical data
• No sending of internal date and time
The conguration and setting of further parameters / thresholds can be done via NFC and its app (BMetering
NFC App). An ‘Active’ eld is provided in the BMetering NFC Cong App that allows you to ‘force’ the radio
transmission by ignoring the passage of the 5 liters.

BATTERY AND REPLACEMENT PROCEDURES
The radio module constantly monitors the battery status (maximum duration: 10 years) and reports the
upcoming discharge via NFC or WM-BUS radio. The notification occurs one year before the total discharge.
For replacement, contact the manufacturer.
The instrument is equipped with a non-rechargeable battery, which can be dangerous if used
improperly. To reduce the risks, the following precautions must be observed:
