  • The importance of Dynamic density compensation in Water level monitoring

    OBTAINING SUPERIOR WATER LEVEL ACCURACY IN COASTAL ENVIRONMENTS In-Situ Inc. water level instruments measure the sum of all pressures (atmospheric and hydrostatic) exerted on a pressure transducer and use that data to calculate water levels. Water density contributes to the total hydrostatic pressure. Saltwater has a higher specific gravity than fresh water. A standard column of saltwater ...

  • OTT Hydromet sensors for measuring water level in creeks and bayous, played a critical role during Hurricane Harvey

    Hurricane Harvey, and the subsequent flooding, was an unprecedented and devastating event in eastern Texas. Harvey produced an average of 33.7 inches of rainfall over the 1,777 square miles of Harris County over a 4 day period which equates to 1 trillion gallons of water and is also 68% of the yearly annual rainfall. Of the 22 watersheds across Harris County, 13 established new record water ...

  • Case study - Continuous discharge monitoring in Mecklenburg - Germany

    The Wallensteingraben was originally constructed as a channel and is almost 20 km long. In the context of implementing the European Water Framework Directive, goals include improving ecological passability. At the same time a measurement site for the continuous monitoring of discharge quantities was installed.  Products used include OTT SLD, OTT CBS and OTT LogoSens. ...

  • Remote location requires minimum concept - Case study

    A leading power supply provider in Austria took on the project of monitoring water levels at a power plant in Montenegro, in two remote locations where no infrastructure is available for installation. On top of that, site visits could only occur every two months, so a device with remote data transmission capabilities was key. Because of these factors, the customer needed an easy solution for ...

  • Flood water protection in the city of Buenos Aires - Case study

    The Arroyo Mendrano is the second largest channeled stream of water running through Buenos Aires. In case of heavy rainfalls it overflows its banks and causes considerable material damage. When the retention basin which had been especially built to collect large quantities of water during strong precipitation events also overflowed, the government decided to have an alarm-system installed to ...
