Buying Guide

When choosing an ultrasonic gas flow meter, consider:

  • Measurement technology: Ultrasonic meters that rely on sound waves can offer non-contact measurement and are well-suited for gas but may require compatible pipe materials and flow regimes.
  • Accuracy and repeatability: Look for devices with low measurement uncertainty (often ±1% or better) and stable long-term performance under your operating conditions.
  • Temperature and pressure range: Gas metering may involve wide temperature variations; select transducers and electronics rated for the expected environment.
  • Material and corrosion resistance: Gas lines sometimes encounter aggressive components; choose meters with robust housings and suitable wetted materials.
  • Installation and maintenance: Inline meters require proper threading and sealing; consider devices with clear calibration procedures and accessible diagnostics.
  • Units and data logging: Ensure the meter supports desired units (L, m³, QTS, PTS, GAL) and provides real-time plus cumulative data for reporting.

For gas applications, evaluate whether you need a dedicated gas flow meter or a versatile liquid meter capable of accurate gas measurement in particular conditions. EMI protection, waterproofing, and compatibility with your piping standards are critical factors in ensuring reliable operation across industrial environments.
