TTFM 6.1 Transit Time Flow Meter
Status (cont.)
Exp. SOS
Displays the expected fluid speed of sound
measurement, in units that match the Velocity. The
expected speed of sound is based on the pipe, fluid, and
temperature selection in the Setup menu.
Meas. SOS
Displays the measured fluid speed of sound, in units that
match Exp. SOS. The meter calculates this value based
on the time it takes for the signal to arrive from one
transducer to another. Large differences between
expected and measured speed of sound (> 10%) typically
indicate an error in the setup of the instrument. Verify
the following are correct in the Setup menu and with the
physical installation of the transducers:
- Pipe Material
- Pipe OD
- Pipe Wall Thickness
- Liner Type
- Liner Thickness
- Fluid Type
- Fluid Temperature
- Crossings
- Separation Distance
