Flowmetrix is the exclusive Canadian representative of Accusonic flow meter sales and services.

Accusonic Flow meters are used in large pipes, channels, buried conduits and rivers for high accuracy flow rate measurement. The systems use the multiple-parallel-path acoustic transit-time method to measure flow velocities at discrete elevations in the measurement section. Real-time flow rates are determined by integration of the flow velocity profile achieving accuracy of up to 0.5% of flow rate. Accusonic has over 2500 systems installed in pipelines 0.5-15 meters in diameter, and in open channels up to 500 meters wide.

Hydroelectric and Thermal Power Plants
Multipath systems have been installed in over 700 hydroelectric penstocks and low-head intakes worldwide. Installations include those in buried and exposed penstocks, pumped-storage plants, and new and existing plants. Systems are used to determine performance curves, establish dispatch guidelines, document plant discharge and evaluate upgrade projects on a before and after basis. At thermal power plants, the meters are used for determining condensers performance and thermal loading of cooling water and receiving waters.

Water / Wastewater
Various water / wastewater projects for the, Greater Vancouver Regional District, New York DEP, City of Chicago, Los Angeles Department of Water and Power and Metropolitan Water District of So. California, have selected Accusonic as their supplier for large pipe and channel flow meter systems. The systems display, record, and output data for both local and remote (via telemetry) data collection.

Treatment, Collection Systems, and CSOs
Todays legislation and regulations require accurate measurement of major wastewater and Combined Sewer Overflow (CSO) discharges. The multipath method is particularly well suited for compound sites that flow from partially full to surcharged and provides high-accuracy data over the full range of flows. Accusonic flow meters provide bi-directional flow measurement which makes them ideal for monitoring tidally influenced sites or conduits subject to reverse-flow conditions. Accusonic flowmeters have been installed in treatment plants, discharge tunnels, CSOs and sewer pipes up to 7 meters in diameter.

Irrigation and Waterways
Irrigation districts and large water projects use Accusonic flow meters for accurate accounting of canal flows. With open channel flow-measurement accuracy up to ± 1.5%, Accusonic meters are excellent in system control and revenue billing applications. Users such as the U.S. Geological Survey have installed Accusonic systems in rivers up to 500 meters wide as part of their nationwide river monitoring system. Accusonic low frequency, high-power transducers are designed for operation in silt-laden and wide rivers. Over 400 river systems have been installed throughout the world.
