Radio module for water meter, type IWM-TX4, compatible with WDE-K50

Radio module for water meter – remote reading and consumption control

This radio module, type IWM-TX4, is designed for wireless remote reading of data from water meters. It is fully compatible with WDE-K50 series water meters, allowing for easy integration with existing measurement systems. Thanks to the Wireless M-BUS technology, the module enables efficient monitoring of water consumption in commercial and industrial applications.

Functionality and application

IWM-TX4 is a solution for installers and managers who want to automate the water meter reading process and gain access to detailed water consumption data. The module allows not only reading the volume but also monitoring reverse flow, detecting tampering attempts, and collecting historical data. This makes it possible to quickly respond to irregularities, optimize water consumption, and minimize losses.

• Remote reading: Eliminates the need for manual water meter reading, saving time and costs.
• Reverse flow monitoring: Allows identification of potential problems in the installation or unauthorized water intake.
• Tamper detection: Protects against water theft attempts by registering module removal or magnetic interference.
• Consumption analysis: Access to historical data (up to 12 months) enables trend analysis and water consumption optimization.
• Alarm signaling: Informs about low battery, tampering attempts, or detection of reverse flow.
• NFC configuration: Enables quick and easy configuration using a smartphone with the Bmetering NFC Config application.
• W-Mbus communication: Compliance with EN13757-4 standard ensures interoperability with other measurement systems.

Construction and technical parameters

The IWM-TX4 module is characterized by a solid construction and a high degree of protection IP68, which guarantees its reliable operation even in harsh environmental conditions. It is powered by a lithium battery with a lifespan of up to 10 years (operating time depends on the settings of the time window and environmental conditions). Communication takes place in the 868 MHz band with a range of up to 500 meters under optimal signal transmission conditions. Small dimensions (100 x 100 x 57 mm) and weight (167 g) facilitate installation and integration with WDE-K50 water meters. The minimum output pulse value is 10 liters (up to DN125) or 100 liters (from DN150). The module operates in a temperature range from +1°C to +55°C. Transmitted data includes consumption volume, reverse flow volume, battery status, and alarms. Measurement accuracy is 0.5%.
