Type
Clamp-on Doppler ultrasonic flow meter (Dynasonics Series DFX)
Velocity
0.05-9 m/s (0.15-30 fps)
Pipe Sizes
Standard clamp-on from 25 mm (1 in); small-pipe transducers 6-25 mm (0.25-1 in)
Liquid

Transducer
DT9 clamp-on; Type 6 / IP67; -40 to 90 C
Fits clamp-on Doppler flow on solids-bearing liquids where you need a Dynasonics Series DFX covering 0.05–9 m/s with ±2% full scale accuracy and NEMA 4X monitoring.
Key advantages
- Velocity — 0.05–9 m/s (0.15–30 fps)
- Accuracy — ±2% full scale over calibrated span
- Pipes — Standard clamp-on from 25 mm (1 in); small-pipe 6–25 mm
- Liquid — ≥100 ppm useful sonic reflectors (>35 µm; ≥25% volume >100 µm)
- I/O — 4–20 mA; dual relay; rate pulse / open collector; AC or 12–28 VDC
Typical applications
- Slurries and aerated liquids with reflectors.
- Non-intrusive clamp-on retrofit.
- NEMA 4X outdoor monitors.
Selection guide
- Pipe size / transducer — DT9; small-pipe options
- Reflectors — Solids/bubbles adequacy
- Power — 100/115/230 VAC vs 12–28 VDC
- Outputs — mA / relays / pulse
Common mistakes
- Clean liquids without sonic reflectors.
- Wrong transducer temperature (−40 to 90 °C).
- Expecting transit-time accuracy on clear water.
When to RFQ / what to tell us
- Pipe material/OD, liquid, velocity, power.
- Outputs; quantity; ship-to.
