Kanalis TT MT - Acoustic Multi-Path Flowmeter


HydroVision‘s Kanalis TT MT is a velocity area open channel ultrasonic flow meter which uses the acoustic “traveltime” method. This method assumes no relation between level and flow, like weirs or flumes. It will correctly determine water flow throughout its designed range by measuring water velocity and depth. For installation in open channels or closed conduits, Kanalis TT MT operates over the fully bi-directional flow range without causing obstruction or head loss. Onsite characteristics such as varying water levels, skew flow or complex channel shapes are taken into account via specific path configurations.
