DYNASONICS DFX DOPPLER ULTRASONIC FLOW METER

Series DFX Ultrasonic Doppler Flow Meters measure the flow of liquids that contain sound reflectors - suspended solids or gas bubbles – greater than 35 micron size. The DFX software automatically adjusts filtering parameters and gain settings so that reliable readings are ensured over a wide range of liquid and reflector conditions. DFX is housed in a NEMA 4X ( IP-66) enclosure and is configured by the user via the front panel keypad. A two-line backlit LCD displays rate and accumulated flow values in user selected measuring units. Power supply options include AC or DC operation and output options include 4-20mA, rate pulse and dual relay. Two transducer types are available with the DFX meter. Series DT9 clamp-on, non-intrusive transducer is recommended for use on most pipes constructed from metal or plastic. The DT9 is rated to NEMA 6P ( IP-68) and has the ability to work with temperatures up to + 400 ° F ( + 200 ° C) . Series DP7 insertion probe transducer is available for installations on pipe systems that do not permit ultrasound penetration. The DP7 inserts into the pipe wall and directly contacts the flowing liquid. Both transducer types can be located up to 990 feet ( 300 meters) from the DFX display enclosure utilizing RG59 coaxial cable. Non-intrusive, clamp-on transducers for most pipes from ¼ " ( 6 mm) and above. Relatively insensitive to VFD and other electronic/ ultrasonic noise. Reduced material costs: clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers, or filters. Reduced installation time: the DFX may be installed and fully operational within minutes. For most homogeneous pipe materials, there is no need to break into pipelines. Microprocessor-based system; configuration and accumulation data stored in non-volatile flash ROM. Wide measuring range: 0.15 to 30 FPS ( 0.05 to 9 MPS) . Insertion probe transducer available for concrete, FRP/ GRP, or wooden pipes. Accuracy ± 2% full scale over calibrated span. Lower maintenance costs: with no moving parts, there is nothing on the DFX to wear down. Reduced down-time: installation may be performed on full pipes and active systems – there is no need to shut the process down for installation or maintenance. Flexibility: with automatic gain control and in-field linearization, the DFX will adapt to a wide variety of applications. Provision for multiple meter, single pipe installation.
