Part Number: EVM430-FR6047 Tool/software: When we calibrate the water meter, there are different constants calibrated at different temperatures and different flows, so we ask TI's experts to help guide us. Project Urgency!! Cash during the holidays…
Part Number: EVM430-FR6047 Tool/software: Hi Cash ,
Good afternoon!
Yesterday we were on the calibration bench with water temperature control, and we did another calibration test,
as follows, the test situation is still not ideal. The attach is our test data…
Hi,
A normal capture shows below. The yellow one is the excitation signal and the blue one is the receive signal.
For my understanding, A V configuration type is more hard to get an acceptable receive signal since it needs to bounce back. I would recommend…

HI TI Experts!
Good afternoon!
1) We are making our own calibration tool, and we need to read the raw VRF data obtained in the MSP430-FR6047 code, how can we obtain the original data.
2)Now in the…
Part Number: EVM430-FR6047 Tool/software: Dear TI experts,
Help with 2 questions about calibration
1】When we refer to the USS Flow + Temperature Calibration format, collect a large amount of data, Flow ID, Temp ID, Ref Flow, Ref Temp, Means Flow dat…
Part Number: EVM430-FR6043 Tool/software: I am working with the EVM430-FR6043 development board for an anemometer application involving 4 ultrasonic sensors . I would like to know how to connect and interface four ultrasonic sensors with this EVM430-FR6043…
Hello Abhijit,
If the device is emitting at 250kHz and you are still using the same 400kHz transducer then this will not work, transducers have a very small window in which they operate. I would suggest using a different clock frequency to drive the TDC1000…
Part Number: MSP430FR6043 Tool/software: I am using MSP430FR6043 to measure water flow using an 8mm diameter tube.
I captured images of signals when there is no flow.
I expected the peak to be in the middle of the received signal. but I can see a peak…
Hi Ido,
Again I think the best next step here is to try calibrating and measuring the flow at the low flow rate, then without changing the calibration, and only changing the meter constant, try measuring a high flow of 1000lph. This would emulate what…
