When ready, the Gotthard base tunnel will be the world’s longest railway tunnel. After a successful initial installation phase in 2006, additional installations for measuring the flows of water from the construction site and the entering well water are required in the section from Faido towards Sedrun in 2009.In the Faido – Sedrun section, the water flows in the drai-nage ducts after the Piora syncline and in the Borel zone are to be measured, the measuring data transferred to the tunnel portal by a suitable data transmission system and processed automatically by customized computer software so that the measuring results can be submitted to the supervisory authorities and the geologists as fully analyzed data sets.
Special solutions for measuring wastewater, raw wastewater and rainwater under the most difficult conditions.
When the impossible becomes possible. High flow velocities, steep gradients, tight spaces, large measuring range. The more difficult the measuring task, the more suitable is the stationary flow measurement, which can often be retrofitted in existing structures and shafts.
