Top Manufacturers of Small-Diameter Electromagnetic Flowmeters

Small electromagnetic flowmeters are critical for many industries. They measure slow-moving liquids with precision. For example, they are used in chemical plants, pharmaceutical factories, food production, and wastewater treatment. These devices work best with conductive fluids like water or chemicals. Additionally, they handle many different flow rates. This makes them perfect for a wide range of uses.

Applications & Fluid Compatibility

Fluids Measured:

  • Acids and bases
  • Salty liquids
  • Wastewater and thick slurries
  • Food-safe liquids (like syrups and drinks)
Best for:

  • Harsh environments with chemicals
  • Thick liquids like honey or sludge
  • Slurries and gritty fluids
  • Clean, sterile processes

How These Flowmeters Work

These flowmeters use Faraday’s Law. This law states that a moving conductive liquid creates a tiny electric signal when passing through a magnetic field. Sensors then measure this signal to calculate the flow speed. Also, they have no moving parts. This makes them very reliable. For example, they work well for low flows (0-10 L/min) and handle all temperatures and pressures without issues.

Key Benefits:

  • No moving parts → Less maintenance needed
  • Accurate at low flows (0-10 L/min)
  • Works in all temperatures and pressures
  • Made with corrosion-resistant materials

Choosing the Right Flowmeter

Flow Speed Tips:

  • Most fluids: 2-4 m/s is best
  • Slurries: Keep under 3 m/s to reduce wear
  • Thick liquids: Use ≤2 m/s to avoid clogs
Sizing Guide:

  • Choose capacity 10-20% bigger than your peak flow
  • Normal use should stay at 50-70% of max capacity
