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.

3Connectors
The XiLOG Data Logger has various connector options, cables and sensors that may be ordered. Sensors or cables supplied
by Ovarro are factory-fitted with the appropriate connector.
XiLOG Data Logger Connectors
3.1 Quick Release Connector (Internal Pressure Transducer)
A male quick-release connector is fitted to loggers fitted
with the internal pressure transducer option. This enables
pressure measurements to be logged.
The integral pressure transducer range is 0-20 Bar.
Caution: Damage may occur if the transducer is subjected
to pressures of more than 150% of its range. The
zero point calibration of the transducer may
change if the logger is subjected to shocks, but
this offset can be compensated by recalibrating
the logger.
Quick-Release Connector
A hose option with male and female connectors is available to connect the logger to a pressure monitoring point.
Caution: Care must be taken to avoid pressure shock when connecting to the transducer, as this can damage or
destroy the sensing diaphragm.
Configuration of the connector is detailed in Section 5.9 Configure Channels - Internal Pressure Screen.

3.2 Analogue Input Connector (Pressure Sensors)
The 6-pin analogue input connector option provides
connection to an external pressure sensor. It is a general
input which may be configured for the measurement of
millivolts, voltage or current.
Loggers fitted with this option are normally configured at
the factory. Ovarro also provide external sensors, which are
calibrated prior to installation.
Note: If the logger starts before the sensor is
connected, no malfunction will occur but the
data up to the time when the sensor was
connected will be zero values.
Analogue Connector
3.2.1 Millivolt Input
The millivolt input option is normally fitted and configured at the factory by Ovarro.
The millivolt pressure sensor must be of a bridge type, producing a differential signal in the 15mV range. The sensor is
powered from the logger via the connector and is of a piezo-electric type commonly found in liquid pressure measurement.
3.2.2 Voltage Input
The voltage input option is normally fitted and configured at the factory by Ovarro.
The voltage input has an input resistance of 47.5kΩ and a range set by the cable supplied with the unit. Voltage input range
is nominally 0 - 2V DC. Voltages outside this range require a specific cable; standard voltage ranges available are 0 - 5V and 0
- 10V. The pressure sensor is powered from the logger via the connector.
Caution: Only the supplied cable should be used, or the calibration will be invalid. The physical input of the logger has
a range of 0-2.50V and is overload protected.
Note: The logger produces 2.8V or 12.8V external power (factory configured) to power an external sensor for the
voltage input. Power is only applied for short intervals during measurement. Frequent sampling will therefore
cause higher drain on the internal battery.
3.2.3 Current Input
The current input option is normally fitted and configured at the factory by Ovarro.
The current input has input resistance of 100Ω and requires a specific cable supplied with the unit. This is suitable for 0 -
10mA, 0 - 20mA and 4 -20mA ranges. The pressure sensor is powered from the logger via the connector.
Caution: Exceeding the 20mA by more than 50% will cause damage to the logger.
Note: The external sensor can be powered from the logger, which applies power for short intervals. 20mA is a high
drain on the internal battery, so external power should be considered.

3.3 Digital Input Connector (Flow Sensors)
The digital input connector option provides connection to an
external flow sensor.
Note: If the logger starts before the sensor is
connected, no malfunction will occur but the
data up to the time when the sensor was
connected will be zero values.

4.3 Connecting Using Bluetooth Communications
Bluetooth communications is automatically enabled when the data logger is powered up. There is no configuration to do.
Bluetooth technology uses the 2.4GHz ISM spectrum band (2400 to 2483.5 MHz), which enables a good balance between
range and data throughput.
The maximum range for Bluetooth communications is approximately 10m (30ft). Maximum communication range will vary
depending on the presence of obstacles, people, walls or electromagnetic environment.
To connect the logger:
1. Start the XiLOG GO app (see Section 5.4 Starting the XiLOG GO Mobile App for details).
2. On the initial page, select the Connect to Device button.
3. The serial numbers of the data loggers within range will now be displayed.
4. Select the required logger by pressing on the serial number.
4.4 Connecting External Sensors and Cables
Installation of XiLOG is principally a matter of connecting the cables for the inputs:
1. Connecting the cables to the logger may carried out in the vehicle prior to siting the logger, or may be done at the
installation site (in “the pit”).
2. Ensure that cable connections are clean and dry when attached.
3. A delay can be configured to allow time to connect cables and install the logger before transmitting data, if required.
However, data transmission before connection presents no problems.
4.5 Siting the Logger
Site the logger at required location:
1. Check that the site has been prepared and that the installation of pipework has been completed in readiness for
installation of the logger. Ensure that the cables will reach their intended connections.
2. Position the logger close to the required pipe location(s) that minimizes any possible ingress of water. This will usually
be at the top-most or highest position possible. The logger is rated IP68 and can withstand periodic flooding but should
not be installed in an area of permanent/frequent flooding or underwater.
3. Ensure that cable connections are clean and dry when attached.
4. Ensure the site is covered and left ready for use.
