  • Case study - Control of dredging works in the Danube River - Austria

    The Austrian waterway management has introduced an automatic system to monitor a series of barges, which calculates the dredged material as a basis for handling invoices of the dredging companies. Before converting to a remote data transmission option, all calculations were entered manually. The datalogger saves the cost for hand-writing documentation of the dredging works by external staff and ...

  • Geostatistically based optimization of a rainfall monitoring network extension: case of the climatically heterogeneous Tunisia

    Rainfall data are an essential input for many simulation models. In fact, these latter have a decisive role in the development and application of rational water policies. Since the accuracy of the simulation depends strongly on the available data, the task of optimizing the monitoring network is of great importance. In this paper, an application is presented aiming at the evaluation of a ...

  • Dual Telemetry with GOES

    Make GOES more effective and reliable with a secondary telemetry option. GOES, for all it’s no-cost, reliable virtues, has some drawbacks. First, it’s a one-way transmission—there’s no way of sending any data to your station. This means there’s no way to reprogram a data logger or reboot a stuck data logger or purge a bubbler without (an unplanned) visit to the site. ...

  • An Overview of Stevens' Approach to Making Remote Communications Simpler, More Flexible and Incredibly Reliable

    The power of the cloud’s simplicity, flexibility and reliability are the attributes at the heart of Measurements to Mind—Stevens’ M2M cloud-based data acquisition vision of shortening the communication path from the sensors to data on-line. What the sensor measures, the mind sees. Products that fly under the M2M ...

  • How can I ensure my export shipments stay within temperature during shipping?

    Q: I need to send shipments overseas, but need to make sure that they have not been temperature abused during shipping. How can I prove to my customers that the goods have stayed within temperature while in transit? A: As you’re sending the goods out to customers you need a datalogger which is low cost and easy to use – I would recommend ...

  • Can I monitor multiple points on one datalogger?

    Yes – using the Ebro EBI-310 USB datalogger you can monitor up to 3 points with one unit. The logger has a built in sensor, but by adding an adapter and external probes the one unit can monitor the temperature of up to 3 locations. This could mean monitoring the laboratory room temperature, ...

  • Monitoring network for Scottish ports - Case Studies

    Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...

  • Commercial microwave links instead of rain gauges: fiction or reality?

    Commercial microwave links (MWLs) were suggested about a decade ago as a new source for quantitative precipitation estimates (QPEs). Meanwhile, the theory is well understood and rainfall monitoring with MWLs is on its way to being a mature technology, with several well-documented case studies, which investigate QPEs from multiple MWLs on the mesoscale. However, the potential of MWLs to observe ...

  • Drought analysis in southern Paraguay, Brazil and northern Argentina: regionalization, occurrence rate and rainfall thresholds

    The objective of the present study is to characterize the drought occurrences in a region comprising Paraguay, southern Brazil and northeastern Argentina. To recognize the drought occurrences the standardized precipitation index at the time-scales of 3 and 6 months was applied to the rainfall records from 1961 to 2011 at 51 rain gauges located in that region. After a drought regionalization ...

  • Infrared satellite rainfall monitoring: relationships between cloud towers, rainfall intensity, and lightning

    Infrared satellite precipitation estimation algorithms rely on relationships between cloud top properties and rainfall. This study is unique in comparing instantaneous (rather than average) precipitation distributions and lightning strikes to satellite-detected cloud tower attributes. Roughly 2/3 of cloud towers represented areas of strong updrafts rising out of the surrounding cloud mass. Half ...
