The Ijinus LOG03V4 is a standalone communicating data logger designed for reliable monitoring across drinking water and wastewater networks. The unit incorporates a long‑life lithium battery and supports multiple communication options, making it suitable for permanent or temporary field installations.
The LOG03V4 offers local radio communication as standard and can be equipped with an interchangeable communication card to support 2G, LTE‑M, NB‑IoT, or LoRaWAN networks. This modular design allows the communication method to be changed without replacing the entire logger, helping water utilities adapt to evolving network requirements.
Configuration is carried out quickly and safely using a wireless radio connection, allowing operators to programme the logger nearby without direct physical connection. With a high internal memory capacity, the LOG03V4 is capable of storing large volumes of data locally before transmission.
The logger supports a range of digital and analogue inputs, enabling connection to flow meters, pressure sensors, rainfall sensors, and other 4–20 mA devices commonly used in water network monitoring. Its robust housing and IP68 ingress protection make it suitable for deployment in demanding underground or outdoor environments.
