How to Choose the Best Clamp-On Ultrasonic Flow Meter Manufacturer

Brand name alone isn’t enough — your choice should be based on real application conditions.
 

① Identify Your Measurement Requirements

• Medium: Water, wastewater, chemicals, oils, slurries

• Pipe material: Carbon steel, stainless steel, PVC, cement

• Pipe size: Small DN20 or large DN2000?

• Accuracy:

  • High accuracy (±0.5%): billing, custody transfer

  • Standard accuracy (±1–2%): industrial monitoring

• Operational conditions:

  • Full pipe?

  • Scaling on inner walls?

  • Strong vibration or noise?

② Consider Budget and Lifecycle Cost

• High budget, critical applications: Siemens, Emerson, FLEXIM

• Best value for money: Aister, Huizhong

• Low budget, simple monitoring: Third-tier domestic brands

③ Check Technical Support & After-Sales Service

Clamp-on ultrasonic flow meters require correct installation, calibration, and sensor positioning.

Good manufacturers offer:
