Doppler fixed ultrasonic flowmeter
DMDF1 Enhanced Ultrasonic Doppler Flowmeters measure 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, or Insertion transducers permit the instrument to be installed in minutes without interrupting system pressure or flow. In addition, no pressure head-loss is created; therefore system pump horsepower requirements are reduced. The DMDF1 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. Ultrasonic doppler flowmeters operate by transmitting and receiving ultrasonic sound signals in liquid. DMDF1 Enhanced Ultrasonic Doppler Flowmeters incorporate dula transducers that are clamped on opposite sides of a liquid filled pipe. Each transducercontains a piezoelectric crystal. DMDF1 features advanced signal processing and an exclusive auto-adapting digital filter to produce accurate and stable indications of flow rate and totalized flows. A full function key pad allows field cinfiguration of pipe size, engineering units, the 4-20mA outpu and all operation parameters. The system can be field configured to pipe sizes ranging from 1 to 120inches [25 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.
