Fits clamp-on dirty-liquid flow where you need a Pulsar Measurement Greyline DFM 6.1. Doppler ultrasonic meter for liquids with solids/bubbles ≥100 μm at ≥75 ppm, pipe ID 0.5 in to 15 ft, velocity ±0.03 to 12.2 m/s, accuracy ±2% of reading or 30 mm/s, and isolated 4–20 mA / 0–5 V plus dual 5 A SPDT relays.
Key advantages
- Mount — Clamp-on Doppler ultrasonic
- Medium — Liquids with solids/bubbles ≥100 μm @ ≥75 ppm
- Pipe — ID 12.7 mm to 4.5 m (0.5 in to 15 ft)
- Accuracy — ±2% of reading or 30 mm/s
- Outputs — 4–20 mA or 0–5 V; 2× 5 A SPDT
Typical applications
- Slurry / wastewater Doppler.
