Isodaq Technology is now part of Hydro International.

Flow Meters

We provide state-of-the-art flow measurement systems carefully selected from internationally renowned manufacturers. As hydrometry specialists, we specialise in open channel and large closed conduit applications where traditional weirs and flumes can't be installed due to site, environmental or hydraulic constraints.

We offer a range of open-channel flow meters for almost any type of channel and hydraulic conditions and enjoy the challenge of applying our extensive experience to select a system that will meet your needs even for the most difficult sites.
