Mobile discharge measurement system for turbulent rivers with unknown cross-section profile - fluorescence tracer

The discharge measurement is performed by using the well-established tracer-dilution method and is especially suitable for high volumes of water. 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 a fluorescent material as tracer. After insertion of a known amount of tracer material two optical fluorescence probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed.

Tradition and Innovation

SOMMER Messtechnik develops and sells sensors and environmental monitoring equipment including system solutions for data recording, data transmission and analysis of the captured data. With more than 30 years of experience SOMMER is a true measurement specialist and reliable partner in hydrography, meteorology, industry and water management, sewage and for geotechnical applications.

Innovative Doppler radar sensors for discharge measurement, unique snow monitoring technology as well as user friendly systems for data management and telemetry give proof of the distinct spirit for innovations in this company. Realising monitoring systems far from any infrastructure and in remote and harsh environments, such as alpine and high alpine weather stations, builds another field of experience of SOMMER Messtechnik.

Milestones of a dynamic corporate development

Back in the mid-1980s the company founder, Mr. Wolfram Sommer, made the step to start his own business. At the beginning still together with a corporate partner, Sommer GmbH & Co KG became an independent company in 1997 and was renamed to Sommer GmbH – better known as SOMMER Messtechnik – in 2013. In the early years the business focus was clearly on the so called home marked, that is Austria, Germany and Switzerland, whereas toady SOMMER holds his ground in a global environment while still being an owner-managed family business. Meanwhile our international sales covers numerous countries around the world and on all continents.
