Salt-Dilution Hydrologic Measurement Equipment

Precise discharge measurements in turbulent streams.

We distribute salt-dilution measurement systems made by the Canadian company Fathom Scientific Ltd. , designed for reliable, autonomous discharge measurements in turbulent streams with unknown cross-sections.

About us

Innovative, field-proven measurement technology

HMS grew out of years of hands-on use of autonomous salt-dilution measurement systems (AutoSalt™) made by the Canadian company Fathom Scientific Ltd. in the European Alps. Over several years of research at the Technical University of Munich (TUM), the AutoSalt system was tested, refined and validated under demanding conditions at three different sites. The results were published in a peer-reviewed scientific paper .
