Ultrasonic Flow Meter Sonic-Pro
by Blue White Industries

Sonic-Pro Hybrid Ultrasonic Flowmeters


  • User-selectable Doppler or Transit Time operating modes for measurement of both clean and dirty fluids

  • The meter can be factory configured for easy installation

  • Custom quality metric algorithms and DSP technology for reliable, high accuracy measurements

  • To allow for changes in the fluid's particle count, SonicPro monitors the signal gain and employs an
    Automatic Gain Control (AGC) algorithm that periodically adjusts the gain, maintaining the optimum power level

  • Smart external communication with simple, intuitive, Sonic-Pro software

  • Portable, rugged carrying case for easy transportation between applications

  • 2 year factory warranty

Features Diagram



Pipe Sizes

    T-Track fitting allows for small pipe diameter capabilities (1/2" - 24")
    Pipe size range 1/2" - 100"


    Virtually any acoustically conductive fluid, Dirty or Clean
    Doppler Mode:

      Requires particles to be present in the flow stream to "reflect" the sound waves. (ie. Air bubbles, sand, etc.)
    Operational Environment:

      fluid contains .02%-15% (200-150,000 ppm) of particles.
    Transit Time Mode:

      Requires relatively "clean" fluid to enable the sound waves to complete a circuit.
    Operational Environment:

      0%-10% (0-100,000 ppm) of particles.


    +/- 1% of rate in Transit-Time mode greater than 1 ft/sec fluid velocity
    +/- 0.01 ft/sec in Transit-Time mode less than 1ft/sec fluid velocity
    +/- 2% of rate in Doppler mode greater than 5 ft/sec fluid velocity
    +/- 0.10 ft/sec in Doppler mode less than 5 ft/sec velocity

Interface & Data
