The Avarro Logger (XiLog4G) is a robust, submersible battery-powered data logger for water-network monitoring that transfers data securely over 4G (LTE CAT1) with 3G/2G fall-back. It offers multiple channel options — dual internal pressure, dual digital (flow) inputs and an analogue input — so events can be qualified confidently and PRVs monitored with dual pressure. Simple wireless configuration via an Android app and an open API for sending data to PrimeWeb or a preferred hosting platform make it fast to deploy and easy to integrate.
