The DFX ultrasonic Doppler flow meter measures flows of liquids containing suspended particles or aerated liquids. The suspended particles must reflect ultrasonic energy. The DFX flow meter operates by transmitting ultrasonic waves into the flow stream and measuring the frequency shift of the reflected wave. The meter has clamp-on design allows quick and low-cost installation, and eliminates worries of fluid compatibility and pressure head loss. A hot-tappable insertion probe transducer is available for installation on pipe systems that do not permit ultrasound penetration. With no moving parts, there is no mechanical wear, so repair kits or replacement parts are not needed.Minimal installation time - the DFX may be installed and fully operational within minutes, for most homogeneous pipe materials, there is no need to break into pipelinesMinimal material costs - clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers or filtersReduced down-time - installation may be performed on full pipes and active systems, there is no need to shut down the process for installation or maintenanceLower maintenance costsNon-intrusive, clamp-on transducers for most pipes from 1/4 Inch (6 mm) and aboveFlexibility - with automatic gain control and in-field linearization, the DFX will adapt to a wide variety of applications6 - 60 sec responseSynchronization provision.
