Tool/software:
Hi expert,
We are currently developing an ultrasonic gas flowmeter using 6043. Now we have discovered a problem as below.
When we test a DN150 flow rate of 1600 cubic meters, the time difference does not increase any more with the increase of flow rate. It remains at a fixed value. Theoretically, the time difference corresponding to 1600m³/h should be 32892ns. I would like to ask that, what is the maximum value of the time difference that can be measured in your relevant algorithm?
This is the waveform corresponding to 1600m³/h, ADC sampling rate 1M, sensor 200kHz:
Many thanks!
Joyce
