Tool/software:
The summary is that the volume flow rate measured by the TI GUI switches between a positive and negative flow rate. Has anyone seen this before? What could be the problem?
I'm using the Audiowell DN25 inline pipe, and all the settings in the GUI are the the default values that TI set for this inline pipe, except the gain which I reduced from 1 dB to -0.8 dB to get a peak signal of +/- 900 ADC counts.
My ADC capture is textbook for 0 flow.
And this picture shows the waveform captures with the volume flow rate switching between positive and negative values...
Thanks in advance for any advice.
