  • Page 11: Time Based Diagnostics

    <.> Time Based Diagnostics This display shows diagnostics relating to the timing measurements being made by the UFM. • Delta Time • Transit Time • Path Time • dT Offset • SOS The absolute upstream transit time through the fluid in the pipe and the absolute downstream transit time through the fluid in the pipe are usually of the order of hundreds of microseconds.
  • Page 12 indicated by numbers from typically -25.0 to +55.0. Normally, the stronger the signal strength detected the better and more reliable the flow measurement is, as well as the more stable the measurement value obtained. Adjust the transducer positioning to the best position, within limits and check to ensure that enough sonic coupling compound is applied during installation in order to obtain the maximum signal strength.

    is prompted to enter a pipe transverse sound velocity. The user is prompted to enter the transverse speed of sound in the pipe. Allowed values are ranged 500 to 7000m/s, default 3206m/s (Carbon Steel default). WTG SOS This value is used to make wall thickness measurements using the UFM when fitted with a wall thickness probe rather than flow transducers, see the Transducer Type parameter below.

    • Z is 1 pass, most common on large diameter pipes. • V is 2 passes, the most commonly used method, simplest to install as both sensors are on the same side of the pipe. • N is 3 passes, used on small diameter pipes. •...
  • Page 24 Calibration Settings Menu This menu allows the user to change calibration and calculation settings. Low Flow Cut If the flow velocity falls below the low flow cutoff value, the measured flow velocity and calculated flow rate indication is driven to zero. This function can prevent the flow meter from reading flow after a pump is shut down but there is still circulating liquid creating movement in the pipe, which will result in a totaling error.
