Groundwater level measurement in Iceland

About our client

The Property Manager, aiming for proactive risk monitoring concerning the flooding of a dozen properties and the active control of the drainage system, required the contractor to provide a comprehensive real-time groundwater level monitoring service.

The core component of this system was to be the installation of measuring devices in key locations, ensuring continuous (24/7) measurement with a maximum data transmission latency of 15 minutes. A crucial element was also a secure cloud platform enabling staff to remotely oversee all measuring points, offering an intuitive visualization of historical trends and data export capabilities. Furthermore, the system needed to feature configurable alarm thresholds that would automatically dispatch email/SMS notifications upon exceeding critical levels, thus guaranteeing an immediate operational response, while also providing for the automated generation of cyclical reports and long-term data archival.

PROBLEM TO SOLVE / TASK

The key challenges involved ensuring long-term battery operation, guaranteeing the reliability of both data transmission and cloud platform performance, and facilitating access to several years of historical data. Crucially, the ability to visualize data from multiple loggers was essential to effectively analyze the temporal correlation between different monitoring points.

SOLUTION

Vista has implemented an NB-IoT water level logger that utilizes a submersible pressure sensor to accurately measure the height of the water column in a well or borehole.

This device is specifically designed for remote monitoring. It employs Narrowband-IoT (NB-IoT) technology to wirelessly transmit the collected water level data directly to a cloud-based platform for storage, visualization, and analysis. This approach ensures low power consumption and wide area coverage, making it ideal for deployment in remote or underground locations.

Users can utilize a free mobile application to easily configure the device and locally read historical data stored in its internal memory. This capability allows for the creation of a complete remote monitoring system.

This versatile solution is suitable for various level measurement and control applications, including:

  • Water tank level measurement and control

  • Liquid level measuring in tanks, rivers, lakes, seas, wells, tubes, and underground water sources

    RESULTS

    By combining these elements, Vista successfully met the client’s requirements for proactive management and reliability:

    • Transmission Reliability: The use of NB-IoT minimizes the risk of data loss, even in challenging terrain conditions.
    • Longevity: Elimination of the need for frequent battery replacement or external power supply.
    • Cost-Effectiveness: Utilization of standard, precise 4-20 mA sensors coupled with the low data transmission costs of NB-IoT technology.
    • Active Response: The ability to set alarms on the cloud platform allows the Property Manager to react immediately to elevated groundwater levels, minimizing the risk of flooding.

    Efento Cloud for hospitals – safety, savings and full control
    A hospital consists of thousands of processes, devices, and rooms whose proper functioning is essential for patient safety. One of these is ensuring proper storage conditions for medicines, vaccines, medical supplies, and laboratory samples.
    Efento devices can also monitor gas and liquid pressure, water leaks, and visitor footfall.
    Efento Cloud enables automated monitoring and control.
    Automated pressure warning systems
    Pressure sensors are installed in water, oil, chemical, or compressed air pipelines for continuous pressure monitoring. In the event of a pressure issue, a PLC controller operates a pump or valve to immediately increase or decrease the pressure. However, most pressure sensors only provide control signals and lack alerting capabilities.
    Differential Pressure Monitoring in Vietnam
    The facility was originally equipped with analog differential pressure gauges, which did not allow for remote monitoring or automated record-keeping to document production conditions.
    Is it necessary to archive reports from the Efento system?
    Data from temperature loggers used in the storage and transport of vaccines must be kept for at least 5 years. In the case of the Efento system, measurement data from the loggers is stored for 6 years. To ensure that nothing is lost (e.g., due to a failure), it is simultaneously saved in two independent data centers (AWS servers).
    We were busy deploying 150,000 NB-IoT sensors – The Things Conference
    The 9th edition of The Things Conference—the premier global IoT event held on September 22–23, 2026, in Amsterdam—brought together over 2,500 experts from around the world.
    We are proud to have been a Bronze Partner of this conference.
