1Introduction
1.1 Overview
XiLOG is the name of Ovarro’s advanced, robust and waterproof (to IP68) range of multi-channel data loggers designed for
the water industry. They may be equipped with a wide variety of sensors for clean and wastewater network monitoring.
Configuration and setup of the data logger is performed remotely using Bluetooth and the XiLOG GO app for mobile phone
or tablet. The specified status/measurement data is stored by the data logger and communicated wirelessly using either 4G
or IOT modem to Primeweb, a cloud-based data collection solution for monitoring water network pressure, flow and leak
location pinpointing.
1.1.1 Sensor Options
XiLOG may be fitted with analogue, digital and water pressure connectors to suit a wide range of flexible sensor options for
collection of status and measurement data:
Flow –analogue and/or digital input connectors may be fitted to enable flow sensors to measure uni-directional or bi-
directional flow. Mechanical, ultrasonic and electromagnetic flow meters are supported.
Pressure –single or dual input pressure connectors may be fitted with internal or external pressure transducers to
enable water pressure to be measured at either side of a Pressure Reducing Valves (PRV), which reduces the water
pressure coming into the home through the main water line and bringing it down to a safe level before the water
reaches plumbing fixtures inside the home.
Depth –analogue and/or digital input connectors may be connected to enable level sensors for open channels, rainfall,
reservoirs, weirs, boreholes, pump events, pipelines, etc.
1.1.2 Remote Configuration
Configuration of the logger is achieved remotely and wirelessly using the XiLOG GO app on a smart phone or tablet via
Bluetooth communications. This significantly reduces set-up times when installing new equipment and when re-configuring
multiple loggers. The XiLOG GO app is available in Android and iOS versions.
1.1.3 Data Logging
The data logger provides a 4GB memory for storage of status/measurement data. Optional Cyclic logging allows data
collection to continue indefinitely; the latest reading overwrites the oldest record when the memory is full.
Accurate measurements to +/-0.1% (of full scale) may be taken at intervals of 1 sec to 24 hours to suit a wide range of
monitoring scenarios.
The data logger provides reporting of current and historic values, and reporting of real-time alarms direct to mobile or email
to permit a quick response to emergency situations such as flooding.
