The RP-30 is a mobile measurement device to measure the surface velocity profile of rivers. With this velocity information and a known cross-section profile. The included software RP-Commander calculates the actual discharge of the river.
The RQ-30 is Sommer's solution for contact-free determination of discharges in rivers and open channels. With its combination of a velocity and level radar together with Sommer's modeling software RQ-Commander measuring and monitoring discharge is as comfortable and easy as it gets. Due to the contact-free design the RQ-30 is not endangered by flotsam during flood events.
The discharge measurement is performed by using the well-established tracer-dilution method. The system can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available or unknown. It is used salt (NaCl) as tracer material. After insertion of a known amount of tracer material two conductivity probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed.

Precise and relaiable ice detection with contact free technology
Ice Detection Sensor to measure icing and freezing rain for various fields of application. The IDS-20 system is setting the standard for the next generation of ice detection systems. The IDS-20 is the first non-contact ice detection system which is able to measure form 0,01mm up to 80mm of ice thickness. The IDS-20 system is an extremely flexible system to cope with different situations and applications. The system contains of a central controller and three different sensors. The sensors have different measurement ranges and applications. There are two cube sensors for icing measurement and icing detection for two different measurement ranges. Therefore, the IDS-Cube 1 sensor has a measurement range of 0,01mm until 1mm and is for the recognition of extremely fine ice layers and icing events. The design of the IDS-Cube 5 sensor is to recognize ice layers and icing events from 0,1 mm up to 5 mm. Additionally there is a rod sensor which is designed to measure the total ice thickness thru out the season or year. The measuring range of the IDS-Rod sensor is form 1mm up to 80mm. The IDS-system design is made to be used with one sensor or up to max two IDS-sensors at the same time.
