DFX Doppler Ultrasonic Flowmeter
The DFX ultrasonic Doppler flow meter measures flows of liquids containing suspended particles or aerated liquids. Used with the DT9 clamp-on, non-intrusive transducers, the meter is suitable for sewage and mud slurries and can be used on most pipes constructed from metal or plastic. The DT9 transducer for the DFX meter is rated to Type 6 (IP67) and has the ability to work with temperatures up to 194° F (90° C).
- Non-intrusive clamp-on design: Installs outside the pipe—no shutdown needed.
- Wide velocity range: Measures from 0.15–30 fps (0.05–9 MPS).
- Low maintenance: No moving parts, no mechanical wear.
- High flexibility: Automatic gain control and in-field linearization for varied pipe types.
- Smart, microprocessor-based system: Easy front-panel programming.
- Clear display: Backlit 2-line LCD for rate and total flow.
- Versatile power & outputs: AC/DC options, with 4–20 mA, relays, and pulse output.
- Durable enclosure: NEMA 4X (IP66) protection.
- Wide pipe size range: Compatible with 0.25–120 in pipes.
- Long cable reach: Transducers can be placed up to 990 ft (300 m) away.
- Sewage & wastewater: Ideal for liquids with solids or gas bubbles—perfect for treatment plants and similar applications.
- Slurries & mud: Handles liquids with suspended particles, including mud and dense slurries.
- Aerated liquids: Accurately measures flows with entrained air from aeration processes.
