TUS Ultrasonic Gas Flowmeter

TUS Ultrasonic Gas Flowmeter

The TUS ultrasonic gas flowmeter has independent intellectual property rights and features high accuracy, high reliability, and high stability. This product adopts multiple acoustic path layouts and supports multiple communication protocols to meet different user needs.

The flowmeter is equipped with a built-in temperature sensor, which can detect the temperature inside the pipeline. It can automatically compensate for the measurement deviation caused by the thermal expansion and contraction of the flowmeter housing, thereby reducing inaccuracy.

Main Advantages

  • Measurement Certification
    OIML Class 0.5 and CPA Class 0.5
  • Structural Features
    Full-bore design with no moving parts, bidirectional measurement supported
  • Ultrasonic Transducer
    Titanium housing, 200 kHz operating frequency, 42 MPa max operating pressure
  • Temperature Compensation
    Built-in high precision sensor compensates measurement deviations from temperature changes
  • Self-diagnosis Function
    Measurement and diagnostic data support accurate equipment condition analysis
  • Cloud Service (Optional)
    4G IoT enables cloud data upload and lifecycle management
