The next-generation data logger is designed for continuous monitoring of water supply networks, providing precise pressure and flow data logging, secure data transmission, and reliable long-term operation in demanding environmental conditions.
Description

Integrated Pressure Measurement

  • 2 internal pressure transducers

  • Measurement range: 0–20 bar

  • Accuracy: ±0.1% of full scale

  • Connection: Male quick release

  • Operating temperature (pressure transducers): from 0°C

Enables analysis of:

  • Static and dynamic pressure

  • Pressure drops

  • Surge events (water hammer)

  • Daily pressure variations

 

Digital Inputs for Flow

  • 2 digital inputs

  • Maximum pulse frequency: 1000 Hz

Logging modes:

  • Average flow rate

  • Volume

  • Digital totaliser

  • Bi-directional flow

  • Combination of two independent pulse streams into a single logged value

Supported calculations:

  • 1 min, 5 min, 15 min averages

  • 24-hour total volume

  • Minimum and maximum values

  • Standard deviation

 

Analogue Inputs

  • 1 × 0–20 mA

  • 1 × 0–2V / 0–5V / 0–10V

  • Accuracy: ±0.1% of full scale

  • Resolution: ±0.025% (12 bit)

Suitable for:

  • External pressure transducers

  • Level sensors

  • Electromagnetic flow meters

  • Other industrial sensors

 

 

Memory

  • 4 GB internal memory

Data Logging

  • Sampling interval: down to 1 minute

  • Cloud data transmission

  • Local data download

  • On-site Bluetooth connectivity

Communication Options

  • 4G / 3G / 2G

  • User-accessible NANO SIM

  • External antenna options

Advanced Underground Antenna

A state-of-the-art antenna specifically designed for underground use, combined with the integrated 4G modem, ensures maximum communication reliability in chambers and buried infrastructure.

Advantages:

  • Increased communication uptime

  • Reliable data transmission in weak signal environments

  • Reduced site visits

 

Power Supply and Operational Life

  • Internal battery: 3.6 V

  • Battery chemistry: Lithium Thionyl Chloride (non-rechargeable)

  • Standard battery life: up to 5 years
    (based on 15-minute logging interval and one transmission per day)

  • Field operational life can be extended to 10–15 years

This significantly reduces:

  • Labour costs

  • Maintenance frequency

  • Total Cost of Ownership (TCO)

 

Environmental Specifications

  • Operating temperature: -20°C to +60°C

  • Maximum relative humidity: 99%

  • Protection class: IP68
    (fully submersible to a depth of 1 m)

 

Specifications

  • Dimensions: 100 × 160 × 44 mm

  • Weight: 530 g

  • Body material: Extruded 6063 Aluminium

  • End caps: 30% glass-filled polypropylene

 

Software Compatibility

  • Centralised data management via Atrium platform

  • Android app for rapid XiLog4G configuration

  • Local on-site data download capability

  • Simple installation and operation
