Hello Cash, Sorry for the late reply. I was out of office Here is an ADC capture Here is a snippet from a waveform where the cycle slip occurred The blue points are the flow measured from our reference device and the green from the device we are trying to calibrate. The value measured at the cycle slip is ~-5000l/h, but the graph would show correctly if the y axis went to this value. Measurements are taken every 250ms and every four measurements are combined into an average, so every second I get a reported l/h value which is shown in the graph above Also I have another question. We are using a custom board and I have the EVM to configure the parameters. After I finish with the configuration of the EVM, I pass the configuration settings to the custom MSP30FR6047 board which has the same pipe, same type of transducer (same MHz, same manufacturer company) and same transducer distance. Except of the meter constant and the VFR Flow and temperature calibration, is there anything else that needs to be changed to get accurate measurements? For example should I do frequency sweep for every device or should I keep the same frequency that I found on the EVM since all of them use the same type of transducer?
