The Ijinus BLUE and Ijinus BLUE‑LP are compact, battery‑powered data loggers designed for water network monitoring and diagnosis. Suitable for permanent or temporary installations, both models provide reliable data acquisition for key network parameters such as flow, pressure, and digital inputs, supporting informed operational and asset management decisions.
The Ijinus BLUE is a versatile logger capable of recording multiple signal types, including pulse inputs, Modbus flow meters, and 4–20 mA signals. Its modular communication system allows the logger to transmit data to SCADA systems using cellular networks (2G, LTE‑M, NB‑IoT) or LoRaWAN, depending on network availability and project requirements. Communication cards can be replaced on site without removing the logger, simplifying maintenance and reducing downtime.
The Ijinus BLUE‑LP includes all the functionality of the BLUE, with the addition of a built‑in pressure sensor. This integrated sensor enables direct pressure monitoring without the need for an external pressure transducer, making the BLUE‑LP particularly suited to applications where pressure performance and transient monitoring are required. This is the key difference between the two models: the BLUE‑LP includes an integrated pressure sensor, while the BLUE does not.
Both loggers are engineered for long‑term deployment in demanding environments, featuring IP68 sealing, high memory capacity, and drinking water certifications, making them suitable for use across potable water networks. Configuration can be carried out wirelessly on site, supporting efficient installation and commissioning.
