Standard Diagnostic Terminology
Chord Velocity: (or Path Velocity)- The average velocity (ft/sec) along the chord line between pairs of transducers.- Chord A shows 17.4 ft/sec- Blue bars indicate reverse flow
Average Velocity:
- The path weighted average of all pathsaverage velocity of the entire cross-sectionof the meter
Flow Veloci ty Ratio:- The decimal ratio of an individual chords velocity divided by the meter average
velocity.
- Chord A = 0.892 = 17.43 / 19.54

Standard Diagnostic Terminology (Contd)
Speed of Sound: (SOS)- The sound propagation rate expressed inDistance/Time.(i.e. Ft/Sec )
- The bar for the chord turns yellow if the spread between thechord Speed of Sound and the Average Speed of Sound
varies by more than 0.35%- The bar for the chordturns red if the spreadbetween the chord Speedof Sound and the AverageSpeed of Sound varies
by more than a configurablefactor called CRange

Gain:
- The gain is a setting for how much the meter must amplify areceived signal to make the recorded signal have the requiredamplitude. If sound signal level diminishesgain increases.
- Gains can vary considerably from meter to meter and because ofchanging flow conditions.
- For the same transducer, the gains are higher on larger metersthan smaller meters for a given flow condition because of thelonger path lengths.
- The maximum gain with the LT-01 transducer is 103 dB

Standard Diagnostic Terminology (Contd)
Performance:
- The percentage of acceptable path (transducer pair) timings from the lastrunning test batch.
- A 100% performance means that every signal acquired is used to makethe flow measurement.
- At higher velocities, or in the presence of ultrasonic noise interference, orin changing flow conditions, this value may be less than 100%.
- If the batch size is 20.the last 20 measurements of the sametransducer pair will be reported. The percent range will be 0 to 100%in5% incrementsIE: 90% = 18 of the last 20 timings were successful.
- Performance above 25% is acceptable

Standard Diagnostic Terminology (Contd)
Signal to Noise Ratio: (SNR)
- It is the numeric ratio between thereceived sound signal and thereceived background noise
- This number is a net usable signal number and can have a minimum numeric limitassigned to it and resultant alarms.
- The average signal and noise levels only includes samples used for the batch and donot include samples thrown out due to poor quality.
- If noise appears to be a problem, this SNR can help you determine the direction of thenoise. Lower signal to noise ratios on the upstream chords than on the downstreamchords indicate that the noise is coming from downstream of the meter.
- SNR values below 500 warrant investigation

Advanced Diagnostic Terminology (Contd)
Swirl:- Estimate Swirl from Profile Factor (Consider flow regime
and conditioning)
- A profile factor of 1.17 = 1.042 / 0.89, is equal to a swirl of 0 degrees
- Most Swirl patterns have a continuous rotational component. Swirls that are almostperfectly rotationallike a corkscrew or a threadare usually referred to as BulkRotation
- Flow which is not parallel to the centerline of the longitudinal axis can causemeasurement errors. (greater than +/- 2 degrees of swirl)

Symmetry:
- Ratio of the flow velocities of the top two chordsdivided by the flow velocities of the bottom two chords
- Compares the flow in the top half of the pipe with that in thebottom half
- In good condition it should be close to 1

Standard Diagnostic Terminology (Contd)
Speed of Sound: (SOS)- The sound propagation rate expressed in
Distance/Time.(i.e. Ft/Sec )
- The bar for the chord turns yellow if the spread between thechord Speed of Sound and the Average Speed of Soundvaries by more than 0.35%
- The bar for the chordturns red if the spreadbetween the chord Speedof Sound and the AverageSpeed of Sound varies
by more than a configurablefactor called CRange

Mayor Frecuencia elimina problema de Ruido de Valvula?
RTA: NO!!!!, Las valvulas Whisper Trim generan ruido hasta elrango de los 500KHZ
solo reduce tamao de sensor;
Sensor mas pequeo mayor riesgo de rotura si se expone,
Mayor sensibilidad a la suciedad!!!!!
