Tech-Tipp: OTT netDL Configuration with several SDI-12 Sensors

All new OTT sensors  provide a bus-capable interface, either SDI-12 or the RS 485 based OTT SDI . The special Master Modul of the OTT netDL enables the connection of several sensors to every bus (SDI-12 or OTT SDI). Connect for example an OTT Pluvio² and a Lufft WS510  sensor to one OTT netDL and you get a compact, efficient weather station. Just talk to your personal contact at OTT Hydromet to learn more.

The following Tech-Tipp shows exactly how you connect several SDI-12 sensors to an OTT netDL step by step.

The NEW Radar Precipitation Sensor WS100: Fast, reliable & maintenance free

Learn all you need to know about the new Lufft WS100 precipitation sensor in webinar on November 29, 2017. You are invited to our webinar about the Lufft WS100 radar precipitation sensor. Here you will learn everything important about the measurement technology, installation, calibration, fields of application, product benefits as well as its differentiation from other technologies.

Register now for the Webinar

The Lufft WS100 is a maintenance-free radar precipitation sensor for meteorological monitoring. The only one of its kind – it recognizes the type and amount of precipitation from the first drop, and is preferred for remote locations.


The WS100 helps to make important operational decisions within a few seconds. Due to the modern radar technology, the sensor detects precipitation from the first drop. It measures not only the quantity, but also the type of precipitation. The sensor also detects the drop size and divides it into one of the eleven different rainfall classes.

Maintenance-free operation through ingenious technology without any moving parts. This distinguishes the sensor significantly from other methods for measuring precipitation such as the tipping bucket, the weighing principle or the optical method.

The WS100, with unprecedented speed, precisely measures precipitation from the first drop. It measures the precipitation intensity up to 200 mm per hour and detects drops with a size of up to 5.0 mm.

Using a 24-GHz Doppler radar, it measures the speed of all forms of condensed water that can be observed on the Earth’s surface or in the atmosphere. These include rain, freezing rain, hail, snow and sleet.

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 levels during Harvey surpassing previous records by Tropical Storm Allison (2001), Tropical Claudette (1979) and the @016 Tax Day flooding. The Harris County Flood Control District was first established in 1937 following two major floods within six years and started installing their Flood Warning System in 1982 and was at the epicenter of the flooding associated with Hurricane Harvey.  Since 2010, the District has partnered with OTT Hydromet to expand their real time network, and install various sensors which measure water level responses in creeks and bayous. Water level measurements provide critical information needed by first responders and the National Weather Service when making decisions on issuing targeted flood warnings and properly messaging needed actions.
