Good bye 2019! What were this year’s highlights at OTT HydroMet?

On the occasion of the forthcoming end of the year, we take a look at its highlights.



This year OTT HydroMet successfully launched the following new products:

The OTT ecoLog 1000 water level logger with 4G mobile communication launched in August

We present: the brand new OTT ecoLog 1000 water level logger

The OTT ecoLog 1000 is a self-contained, cellular groundwater level logger for measuring water level and temperature using a ceramic pressure cell. It makes your measuring network future-proof through 4G (LTE)/ 2G mobile communication and provides reliable system up-time as well as accurate measurements while avoiding data gaps. The mobile communication unit allows remote configuration and monitoring to avoid costly trips to your measurement site. The data is transferred encrypted with automatic retries if transmission fails.

The new water level logger supports mobile devices, smart phones, and tablets operating with Android, iOS or Windows 10 and can be managed using the responsive LinkComm App. Also, the cable length can be adjusted comfortably on-site. As the successor of the well-established OTT ecoLog 500 it will replace it completely in 2020.

Learn more about the new OTT ecoLog 1000 in a recording of the intro webinar.

The ISE sensors for the HYDROLAB series of water quality sondes launched in October

The newly introduced ISE sensors for HL7 and HL4 water quality sondes

ISE stands for “ion-selective electrode” and describes a sensor that converts the activity of a certain ion dissolved in water into an electrical potential. The newly introduced ISE sensors for ammonium, nitrate and chloride from HYDROLAB are robust and work in water depths of up to 15 meters.

They are especially suitable for spot measurements where the sensors are calibrated prior to the measurement campaign. Frequent quality checks and re-calibrations are required for longer periods of use. The HYDROLAB probes HL4 and HL7 support the user with a sophisticated maintenance and information concept. When connected to the operating software, the probe uses status displays to indicate whether calibration of the respective sensors is necessary. Calibrations can be carried out quickly and easily using guided calibration routines.

The HydroMet View monitoring software for the German speaking market so far launched in November

The HydroMet View software

The new HydroMet View is a elaborated software for data management, visualization and alarming tasks. It was developed with the help of our partner Kisters – a renowned engineering company and experienced software developer founded in 1963.

HydroMet View is browser-based and therefore accessible from anywhere – even via smartphone or tablet. The software enables access to critical water level, discharge or precipitation data for flood or heavy rain events as well as current webcam images. The collected data is stored in Germany in accordance with EU regulations. In addition, the HydroMet View guarantees you reliable service availability, even in the event of high access rates e.g. in the event of an alarm.

The HydroMet View software is particularly suitable for the new OTT ecoLog 1000 water level logger, non-contact radar level sensors, rain gauges and more. It is therefore ideal for flood warning systems, which are playing an increasingly important role due to the growing number of devastating flood events such as in Venice, France or Kenya.

So far the new monitoring software was launched in German-speaking countries but will be rolled out to further countries or languages in 2020.

OTT Water Level Logger Used in Small Irrigation Channels in Valencia, Spain

The irrigation sector in the Valencia area was forced to start measuring the levels in their channels. For this a simple system was required and a very discrete installation needed due to high chances of vandalism and low budgets available from the customer. The OTT HydroMet solution complied with their needs.

Monitoring ditch water quality using OTT ecoN, Hydrolab HL4 and XLink 500

The RIVM in the Netherlands is using the OTT ecoN and the Hydrolab HL4, connected to an XLink 500 datalogger, to monitor the temporal variation of nutrients in ditch water. The data is sent to Hydromet Cloud.

65 new OTT ecoLog 500 stations in Denmark for a crop cutting research project

The associated sets of water level and water flow data, together with detailed records of the physical conditions, can form the basis for calculating the specific effects of the crop cutting on the water level and the manning number (expressing the resistance to the water’s free flow in the watercourse) and the temporal variation thereof. Data can also form the basis for an analysis of how any changes in shape affect both the manning number and the water flow capacity.

New network of weather stations in Sheffield

OTT HydroMet is installing fifteen automatic weather stations as part of the University of Sheffield’s Urban Flows Observatory, which is led by the Departments of Civil and Structural Engineering, and Automatic Control and Systems Engineering (ACSE). The monitoring sites are conveniently located at Sheffield schools, and data from the stations will contribute to the project’s wider environmental monitoring objectives which include the free publication of data.

Groundwater Hybrid Guide published in May

Two billion people worldwide rely on groundwater for their water supply, irrigation for agriculture, and more. But a growing global population combined with climate change, pollution and insufficient groundwater recharge can lead to detrimental effects like droughts, which create costs estimated at USD 80 billion per year.

It has become clear that good, reliable monitoring data is essential to understand which solutions work for effective groundwater resource management.

Learn how you can leverage data to preserve one of earth’s most precious resources with our new guide, compiled of key observations and recommendations from water resource professionals around the globe. The guide covers groundwater trends and over-usage, the evolution of continuous monitoring solutions and give you helpful online resources for further investigation.

Whitepaper: Building Urban Flood Resilience Published in November

Flooding events have been increasing in both frequency and intensity and have historically been most damaging when there was little to no warning. This was due to missing data or misplaced monitoring systems. With state-of-the-art flood and heavy rain monitoring and alarm technologies sophisticated flood resilience networks can be set up. Their real-time data can empower communities, stakeholders, and responders to understand problem areas, take action, and mitigate future risk.

In the related whitepaper you’ll find expert hydrology guidance on how to build flood resilience plans, for any stage of your current network. Learn how to use our five-step plan to achieve flood resilience through monitoring.

Product Guide on Flood Warning Bundle Solutions Published in November

In this product guide you can learn, how flooding monitoring networks can be set up, which monitoring network components make sense for establishing flood warning systems, which points should be considered for the selection of the sensors and which data management options are available. The shown an expert-crafted solutions refer to alarm level gauge and precipitation gauge systems.

In 2020 especially the new remote operation through mobile communication generation 4G or LTE will be an important topic. We’ll continue to provide future-proof measurement technology in terms of data transfer, integrability and usability. The latter especially refers to the operation of sensor systems using own portable devices such as a smartphone or tablet, which is possible e.g. for the OTT ecoLog 1000 and other loggers through the LinkComm app. This also includes the need for state-of-the-art software, which challenges us to further develop existing in-house or externally developed solutions – such as the new HydroMet View.

The future is exciting and we’re looking forward to a new year with new challenges!

With this in mind, we wish you contemplative holidays and a happy new year!
