Isodaq Technology is now part of Hydro International.

River Gauging Systems

As the UK's leading supplier of hydrometric systems, we offer a range of current-meter systems for streamflow gauging to suit most budgets or levels of training, including both traditional current-meter gauging systems as well as modern Acoustic Doppler Current Profiling (ADCP) methods.   We are the official UK and Irish distributor for Teledyne RDi ADCP velocity profilers.
