  • Nominal Diameter: DN50 (50 mm)
  • Measurement Medium: Liquid, gas, steam

Detailed content

  • Accuracy: ±0.75% of reading for liquids; ±1% of reading for gas and steam
  • Repeatability: ±0.2% of reading
  • Flow Velocity Range: 0.3–10 m/s (liquid); 3–80 m/s (gas/steam)
  • Operating Temperature: -29°C to +250°C (standard); -196°C to +100°C (low-temperature type); up to +450°C (high-temperature type)

  • Protection Rating: IP67 (NEMA 4X)
  • Wetted Materials: 316 stainless steel, Hastelloy C (optional)

    Key Features

  • SSP Technology: Advanced digital signal processing filters out noise from pipe vibration and fluid turbulence, ensuring stable output even at low flow rates.
  • Self-Diagnosis: Monitors and alerts for abnormal conditions such as excessive vibration, flow disturbances, and sensor fouling.
  • Bidirectional Flow Measurement: Accurately measures forward and reverse flow.
  • Low Pressure Loss: Optimized bluff body design minimizes energy consumption.
  • No Moving Parts: Virtually maintenance-free with a long service life.

    Applications

  • Oil and gas industry: Measurement of natural gas, crude oil, and process steam.
  • Chemical and petrochemical plants: Monitoring of various process fluids and gases.
  • Power generation: Boiler feedwater, steam, and condensate flow measurement.
  • Water and wastewater treatment: Raw water, clean water, and sludge flow monitoring.
  • Food and beverage: Sanitary flow measurement of liquids and gases.
