Manual Datasheet

The D902 Portable Ultrasonic Doppler Flowmeter measures solids-bearing or aerated liquids in metal or plastic pipe. Proprietary circuitry allows this instrument to operate with lower concentrations of suspended solids than any competitive Doppler flowmeter - expanding the instrument's range of applications and reliability. Clamp-on, non-invasive transducers permit the instrument to be installed in minutes without interrupting system pressure or flow. The watertight case contains a rechargeable battery that can operate the unit continuously for 8 hours.
 

The D902 transmitter has a full keypad designed for simple field setup and application versatility. The two-line, backlit, alphanumeric display shows instantaneous flow rate and totalized flows in a variety of user selectable engineering units.
 

Features:

  • The system can be field configured to pipe sizes ranging from 0.25 to 120 inches [6 to 3050 mm]
  • Non-fouling transducer is immune to build-up of grease, paraffin and other coating materials
  • Solid-state measurement never requires re-calibration and is virtually maintenance-free
  • Operates with relatively clean liquids as well as liquids with concentrations of suspended solids or aeration
  • Does not require long straight runs of pipe
  • Rugged NEMA 4X design permits extended outdoor and rough service use
  • Industry standard outputs allow direct interface to loggers and controls systems
