OTT partners with water resource professionals, organizations, and locations in need of generating reliable data throughout the entire water cycle.

In 2017, the OTT team partnered with the municipal civil engineering office of Bonn to equip two streams with high damage potential and some large catchment areas with measuring stations at twelve critical points. The subsequent data is collected to locally limit severe weather warnings and to detect an overloading of the streams at an early stage. OTT sensors measure the water level around the clock, fully automatically, and send this data via UMTS/LTE to a traffic computer. In addition, video cameras are used to transmit pictures of the situation on site to the control centre. This makes it possible to warn residents and emergency services more specifically and earlier so that they can take final protective measures.

Flow Measurement under difficult conditions: Successful Installation of OTT SVR 100

Background

At the Bad Aibling Triftbach water gauge in Rosenheim, Bavaria, the backwater caused by the Mangfall, a tributary of the Inn, during flooding is a major challenge. In such a case, the existing Stage Discharge relationship provides poor data. Sensors that work with the ultrasonic Doppler principle are unsuitable because the river is fed by discharge from a power plant so high aeration levels are regularly an issue.

The non-contact measurement of water level and flow velocity by means of radar has advantages especially in waters with high biological activity or large sediment loads and in case of flooding. As the sensors are not in the water, they are not clogged and require very little maintenance. In the event of flooding, the sensors are safe from damage from floating debris outside the body of water. In contrast to sensors based on the acoustic Doppler method, this solution also works with very turbid water, high sediment loads or high oxygen content and air bubbles, as is often the case with heavy rainfall and flood events.

Introducing the OTT ecoN​

New generation of UV Nitrate Sensors

Nutrient monitoring is becoming more important as time goes on – as human activity increases the natural amount of nitrate in water, plants and organisms are more and more negatively affected.

Current nutrient monitoring relies on low temporal frequency monitoring and spot-checking, which are vulnerable to uncertainties and less representative of the waterbody. They also aren’t equipped to measure episodic events, which are time sensitive and unpredictable.
Monitoring is moving more towards continuous measurements, which allows for more effective pollution reduction strategies and prioritization of infrastructure investments. More data also means a better understanding of where to focus data monitoring and conservation efforts.
It is far more cost-effective to prevent contamination in the first place than it is to treat existing contamination. This has led to an increased demand for sensors that deliver continuous data, both spatial and temporal, in real-time and with a lower cost per data point.

This is why we’ve released the OTT ecoN, an affordable UV nitrate sensor designed for optical determination of nitrate (NO3-N) in fresh surface and groundwater. Here’s why you should consider the OTT ecoN for your stations in the field.

Live Webinar: OTT SVR 100 radar sensor – contact-free reliable and maintenance-free measurements

OTT_SVR_100_Blog
The measurement of the velocity at the water surface is one of the oldest hydrometric measuring methods, time-tested and easy to carry out with the aid of surface floats. While float measurements are only temporarily applicable and often error-prone, modern radar sensors can determine the surface velocity in real time and with a very high measuring accuracy around the clock.

Learn more about the functional principle and the advantages of contact fee surface water velocity measurement with the OTT SVR 100 as well as the application possibilities for continuous flow measurement in rivers, streams and canals (irrigation canals, service water canals). Reliable measurement results and knowledge of the quality of your data, especially in extreme events with high outflows, can make the decisive difference and provide important insights for critical decisions.

Contents of the webinar:

  • Measuring principle of the radar velocity measurement
  • Limits of operation and technical data
  • Measuring data and metadata on the measurement Quality
  • System solutions for the continuous discharge OTT SVR 100
  • Notes on measuring site selection, installation, operation and calibration
