Spiez hydropower plant, Wimmis weir

Flow measurement Wimmis

The BKW power plants of Berne, Switzerland, measure the wa-ter flowing to the Spiez hydropower plant at the Wimmis weir. The water flow is measured by an ultrasonic time domain meter from STEBATEC. Fairly high peak discharge flow rate of up to 15 cubic meters a second as well as the plulsating, turbulent flow conditions are particular challenges to the measuring equipment.

Full renewal of a stormwater basin for the City of Grenchen

The City of Grenchen is currently renewing itsfour stormwater basins constructed in differentyears. The first such basin to be refurbished isthe second-oldest and the biggest of the four basins built in 1975 ad named after the publicswimming pool nearby. The basin had a numberof structural defects but most pressing were therectification of issues of operating the basin andproblems of work safety.

NEAT; Consorzio TAT Tunnel Alptransit Ticino

Gotthard base tunnel

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.
ARA Radet im Wallis (Schweiz)

High-precision overflow measurement with IDM

The waste water treatment plant Radet near Leukin the canton of Wallis treats the waste water of12 municipalities. Recently, the administration union had installed additional measuring pointsin the sewerage system to improve the billing accuracy. However, the inflow to the treatment plant was still not measured. That would have required substantial input at the construction end and caused unreasonable cost.
Successful completion of the first INKA phase

INKA project is on course

About 110 participants from four countries and three language regions met to celebrate the completion of the first INKA phase in mid-Maythis year. Among them were also representatives of eight cantonal water protection authorities and from more than 30 planning companies. Intense interest focused on the full-day conference organized by STEBATEC AG at their headquarters in Brügg at which all aspects of this futureoriented project to operate sewer systems more efficiently, make more balanced use of sewage treatment plants and improve water pollution control were discussed.
Flow measurement WWTP Kloten Stationary partially filled TF DN 1000
2x Partially Filled Flow Measurement Stationary TF Nominal Size 1000

Inlet measurements of the new Kloten/Opfikon wastewater treatment plant

The Kloten/Opfikon wastewater treatment plant treats wastewater from Zurich Airport and the towns of Kloten and Opfikon. For more than ten years, the Kloten wastewater treatment plant has relied on STEBATEC measurement technology to ensure that wastewater treatment costs are billed according to the source. With the new construction of the wastewater treatment plant, the latest technology has now also been installed: two stationary partially filled flow meters TF with a nominal diameter of 1000.
Zulaufmessung Laufen AG

Laufen Keramikwerk

Keramik Laufen AG is one of the world’s leading manufacturers of bathroom products. The factory produces waste water, which is disposed of in the local sewage treatment plant. In order to draw up a consumer-oriented cost statement, the waste water in the plant’s outlet, as well as the inflow into the plant, must be precisely measured.
