ZENNER NDC-communication module with wireless M-Bus radio interface

Communication module to connect to ZENNER ultrasonic water meter series IUW / IUWS.

The NDC communication module (Near Field Data Capture module) with wM-bus interface is used for remote reading of the ZENNER ultrasonic water meter series IUW / IUWS. The NDC queries the consumption and status information via the NFC interface of the respective meter and transmits this wirelessly. The NDC forwards the data unchanged to the LoRaWAN gateways within range.

An NDC module is always required for radio reading of the IUW ultrasonic bulk water meters. It functions as an external radio module and has a cable length of three meters.

The IUWS ultrasonic water meter is equipped with an integrated radio module. Optionally, the NDC module can be used to optimize the radio range at difficult installation points.

Depending on the version, transmission interval and environmental conditions, the module can achieve a battery life of approx. 10 years.
