OMEGA Engineering D904-A1NA-NN FD-7000 Portable Doppler Ultrasonic Flow Meter

Description

OMEGA Engineering
Portable Doppler Ultrasonic Flow Meter
D904-A1NA-NN
The 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 D904 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.
