DOPPLER OVERVIEW
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. 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 from the DFX display enclosure
utilizing RG59 coaxial cable.
DFX comes with one set of wall mount brackets and one installation
manual. Transducers come with mounting straps and acoustic couplants.
