M91
Displays the Time Ratio between the Measured Total Transit Time and the Calculated
time. If the pipe parameters are entered correctly and the transducers are properly
installed, the ratio value should be in the range of 100
±
3%. Otherwise the entered
parameters and the transducer installation should be checked.
