Fluvius TT ECM-IE – Ultrasonic Multi-Path Flowmeter
The Fluvius TT ECM- IE is an open-channel flowmeter for discharge measurement in rivers and open channels. The range of application for Fluvius TT transit-time ultrasonic flowmeter runs from small waterways to huge river systems with high levels of suspended solids. Specially configured acoustic signals are transmitted through the water from one transducer to another. The transit time and flow rate is calculated providing the speed of river flow. When an acoustic wave propagates in water, part of the energy is damped by friction and suspended solids. This procedure is frequency related. The higher the frequency, the more the damping occurs. For wider distances we use low frequencies as they allow for a considerably better signal at the receiving transducer.
