1 HBRID UTRASONIC FOWMETER <Duosonics> (Pulse Doppler method + Transit Time method) DATA SHEET FSH, FSW, F This meter is the world s first non-intrusive type ultrasonic flowmeter utilizing Pulse Doppler method along with Transit Time method. It enables measurement of velocity profile directly resulting in high accuracy. This makes it suitable for undeveloped flow and for short straight pipes. Pulse Doppler method requires reflectors in the liquid and is utilized on opaque liquids while Transit Time method requires ultrasound penetration and is ideal for clean liquids. The new hybrid technology utilizes both methods in a complementary fashion thus enabling a wider range of applications than it is possible now. In addition, thanks to Fuji s new state-of-the-art algorithm, either method can be automatically switched to accommodate for varying fluid conditions such as concentration of particles and/or air bubbles and flow velocity. Flow transmitter (FSH) FEATURES. Automatic switchover function between Pulse Doppler method utilizing ultrasound reflection and Transit Time method utilizing ultrasound penetration Applicable to various kinds of liquids with/without air bubbles and/or solid particles Applicable to liquid flow that changes in nature frequently or periodically. High-accuracy non-intrusive (non-contact) volumetric flow rate measurement of liquid flow in closed pipes. Accuracy of.% to % (depending on the measuring mode and pipe size) Clamp-on sensor. Direct measurement of velocity profile in case of Pulse Doppler method High accuracy of.% to.% (correction coefficient unnecessary) Applicable to undeveloped flow (short straight pipe) Applicable to flow hovering in the transitional region between laminar flow and turbulent flow. High speed response:.sec (pulse Doppler method)/.sec (transit time method). Real time monitoring of velocity profile by PC in case of Pulse Doppler method (option). Dual-path option improves performance SPECIFICATIONS Operational specifications System configuration: The system is composed of one/two detectors (Model: FSW) and one Flow transmitter (Model: FSH), realizing single-path/two-path measurement.
