1.0-6.3MPa Electromagnetic Wafer Style Clamp Vortex Flow Meter for Liquids, Gas & Steam - DN15 to DN300
Vortex flow meters measure volume and mass flow of liquids, gases, and steam using the Karman vortex principle. Advanced differential algorithms with isolation, shielding, and filtering technologies provide excellent vibration and noise immunity. Unique sensor packaging ensures reliable long-term performance.
- High accuracy with excellent repeatability
- Non-contact detection element for stable performance and reliability
- Simple, robust construction with no moving parts for long-term operation
- Wide measuring range up to 1:10 (special models up to 15:1)
- Low pressure loss - approximately 1/4 to 1/2 of orifice flowmeters
Ideal for pipeline drainage systems, industrial circulation, wastewater treatment, oil and chemical processing, compressed air measurement, and flow measurement of saturated/overheated steam and natural gas.

Important: When installing after pressure reducing valves, saturated steam undergoes adiabatic expansion. This causes water droplet evaporation and temperature reduction. Ensure proper temperature and humidity conditions to maintain measurement accuracy.
