  • Page 43: Displaying Diagnostic Parameters

    Displaying Diagnostic Parameters As part of its measurement menu, the CTF878 offers a list of diagnostic parameters to aid in troubleshooting in the event of flowcell, transducer, or electrical problems. You can select any diagnostic parameter for display as a measurement (see Displaying and Configuring Data, Chapter 2 of the Programming Manual or Chapter 4 of the Startup Guide ).

  • Page 44: Pipe/Fluid Problems

    The gas must be homogeneous, single-phase and relatively clean. Although a low level of entrained particles may have little effect on the operation of the CTF878, excessive amounts of solid or liquid particles will absorb or disperse the ultrasound signals. This interference with the ultrasound transmissions through the gas will cause inaccurate flow rate measurements.
