Description

Description
The AI.FFdopplerIF-W is a clamp-on ultrasonic Doppler flowmeter for accurate volumetric flow measurement in closed pipes conveying dirty liquids, slurries or air-entrained fluids. Using Doppler backscatter from suspended particles or bubbles, it delivers reliable readings where transit-time meters cannot operate. The clamp-on sensors attach externally for non-invasive installation and continuous monitoring without pipe penetration or line shutdown.

Key features
  • Installation range: suitable for pipe diameters from 40 mm to 4000 mm
  • Low-flow sensitivity: velocity measurement from 0.05 m/s up to 12 m/s
  • High-temperature transducers: operational between -35°C and +200°C
  • Rugged construction: control unit in fiberglass enclosure rated IP66 and sensors up to IP68 for harsh environments
  • Easy integration: 4-20 mA outputs, relays and OCT for PLC or SCADA connection


Common applications
  • Raw wastewater and drainage
  • Activated and chemical sludges
  • Groundwater monitoring and mining recirculation


Technical specifications
  • Accuracy: 0.5% – 2.0% F.S.
  • Display: 2-line LCD (velocity and resettable total)
  • Power supply: 85–265 VAC or 24 VDC
  • Sensor material: aluminum
  • Cable length: standard 10 m (extendable up to 300 m)
  • Installation note: For optimal Doppler response, the fluid should contain at least 100 ppm of reflective particles, with at least 20% larger than 100 μm
