Dear Engineers,
We are working with the TI MSP430FR6047 evaluation board to measure flow rate and volume. In our measurements, everything seems to work correctly, and the ToF is well correlated with the changing flow rate. However, we observe occasional jumps in the flow rate. As shown in the attached picture, there is approximately a 1.5% fluctuation under a constant flow rate.
| Value | Difference vs. Reference | Percentage Difference |
|---|---|---|
| 4.030336 (Reference) | 0.000000 | 0.00% |
| 4.087739 | +0.057403 | +1.42% |
| 4.025302 | −0.005034 | −0.125% |
First question: Would you please let me know how I can obtain a much more stable value? What should be changed or improved in my code?
Second question: How can I read out the accumulated volume value? Is the accumulated volume already calculated in the USS library, or do I need to calculate it myself? If I need to implement it myself, how should I do that?
Regards,
