Quick User Guide – IWM-LR4_QUG
Product description
The
IWM-LR4
module is a device that allows to transmit the reading data detected by
WDE-K50 water meters manufactured by B METERS.
The device is already preconfigured in OTAA mode with preset keys. The keys (DevEUI,
AppEUI and AppKey) are provided by BMETERS. For various needs, the modules can be
configured in Activation By Personalization (ABP) mode via Android App. The application
allows you to configure the module by choosing the different operating options. Please
refer to the configuration app manual for a detailed description of the configuration
features and options available.

* Batteries are not replaceable, DO NOT ATTEMPT TO REPLEACE. Any attempt will void
the warranty, moreover will irreversibly damage the device.
** The battery life strongly depends on the working time window, set during the
configuration process, and on the environmental conditions. Estimation of the battery
life is given by the configuration software.
***IP68: maximum 24 hours of continuous submersion at 1 m depth
****Under optimal propagation conditions, the radio range depends on physical
conditions (building constructions, climatic conditions, …) where propagation of the radio
signal can therefore vary.
Installation
The installation of the
IWM-LR4
module is allowed on the WDE-K50 meters only (from
DN50 to DN200).
It is recommended to install the
IWM-LR4
module away from metal objects or any
potential radio shielding, in a place protected from tampering.
Provision the network server in which you want to integrate the sensor (AppEUI) and
provide the application server with the unique DevEUI and AppKey keys. The installer has
the task of checking the propagation conditions of the radio signal during installation.
Commissioning
Make sure that you have respected the installation conditions described above and that
the module is positioned within the operating range of the LoRa gateway installed.
Remove the aluminum sticker applied on the bottom of the module and mount it on
the meter as shown in the pictures. It is necessary to combine the hooks of the meter
with the ones on the module [1]. With one hand keep the meter steady, with the other
hand push the module gently towards the dial [2] and pull it in the direction shown by
the arrow [3/4]. Proceed with the configuration of the K index (10 for all diameters up to
DN125 included or 100 for diameters DN150 and DN200). Before proceeding with this, it
is necessary to read the module to avoid incorrect LORA keys writing.
To initialize the module and send joining requests to the desired network server, it is
necessary to let the inductive index of the dial rotate for +/-5 revolutions (on the
WDE-K50 models, this corresponds to +/- 50 or 500 liters, depending on the K value set).
Verify then that the module has joined the network server in the next few moments.
Configuration by using Android App + NFC Device (for ABP mode or parameter modification)
:
to initialize the configuration process, place the NFC antenna of the android device near
the module as shown in the picture. For the complete configuration instructions, please
refer to the app manual.
To avoid possible frauds on the module, it is recommended to tighten the mounting
screw supplied and apply the adhesive seal.
