🌊 Siemens SITRANS F Flowmeters – Overview

• Used for flow measurement of liquids, gases, and steam
• Covers multiple technologies for different applications
• Widely used in:
  • Water & wastewater
  • Oil & gas
  • Power plants
  • Chemical & food industries

⚙️ 1. Magnetic Flowmeters (SITRANS F M) 🔹 Principle:

• Based on Faraday’s Law of Electromagnetic Induction

🔹 How it works:

• Conductive liquid flows through a magnetic field → generates voltage → proportional to flow

🔹 Key Features:

• No moving parts
• High accuracy (~±0.4%)
• Works only with conductive fluids

🔹 Applications:

• Water, sewage, slurry, chemicals

👉 Example models:

• MAG 3100, MAG 5100, MAG 8000

⚖️ 2. Coriolis Flowmeters (SITRANS F C) 🔹 Principle:

• Based on Coriolis effect (mass flow measurement)

🔹 How it works:

• Fluid flows through vibrating tubes → phase shift → mass flow calculated

🔹 Key Features:

• Measures:
  • Mass flow
  • Density
  • Temperature
• Very high accuracy

🔹 Applications:

• Oil & gas
• Chemicals
• Food processing

👉 Advantage:

• Direct mass flow measurement (no need for density correction)

🌪️ 3. Vortex Flowmeters (SITRANS F X) 🔹 Principle:

• Von Kármán vortex shedding

🔹 How it works:

• Fluid passes a bluff body → vortices form → frequency ∝ flow

🔹 Key Features:

• Suitable for:
  • Steam
  • Gas
  • Liquids
• Can measure energy (steam systems)

🔹 Applications:

• Boilers
• Steam lines
• Utility systems

👉 Example:

• FX300, FX330

🌐 4. Ultrasonic Flowmeters (SITRANS F US / FS) 🔹 Principle:

• Uses ultrasonic sound waves

🔹 Types:

• Inline (in contact with fluid)
• Clamp-on (outside pipe, non-invasive)

🔹 Key Features:

• No pressure drop
• Works for clean or slightly dirty liquids
• Clamp-on → no pipe cutting

🔹 Applications:

• Large pipelines
• Water distribution
• Temporary measurements

👉 Example:

• FS220, FS230, FUS060
