Part Number: MSP430FR6047
Other Parts Discussed in Thread: MSP430FR6043
I have designed a water flowmeter using MSP430FR6047 by using MSP430FR6047 EVM as a reference so that it works with the Ultrasonic Sensing Design Center. Please see ADC Capture and the Waveform captured for Delta ToF. The noise level is quite high. Attached is the USS_userConfig.h that is used in my firmware.
Any advice on what could be causing the high noise level

Hi,
Thanks for your reply.
The ADC waveform is not good here, can you show your configuration picture, and which transducer you used?
Can you eloborate about the not good. I just need to know what to expect and what is the ideal kind of waveform.
I did not set thru the GUI configuration. I change the setting on the USS_userConfig.h. I will attached the file here for your perusal .
AS for the hardware setup, I can show u the sketch of the setup. The signal ultrasonic transducer input is weak. As you can see from the attached file, I used maximum gain. The measure AbsTOF is only about 7us with tube and liquid as transmission medium. There are a few noob question I would like to ask
1) What is the best way to secure the piezoelectric transducer. Any recommended adhesive?
2) How to improve the strength of the ultrasonic transmission? CAn I use a buffer to drive the transducer (5V or 12V)
3) If both Upstream and Downstream transducer is connected on the same frame, wouldn't the ultrasonic vibration transmitted through the frame or the the sidewall of the tube?
Hi,
See my comments as below:
Good waveform as your reference:
1) What is the best way to secure the piezoelectric transducer. Any recommended adhesive?
[ANS]For metering transducer, the power is small, thus will don't have mechanical shack, use some simple method should be fine.
2) How to improve the strength of the ultrasonic transmission? CAn I use a buffer to drive the transducer (5V or 12V)
[ANS] yes, but you will need external circuit, MSP430FR6047 EVM only support 3.3V.
3) If both Upstream and Downstream transducer is connected on the same frame, wouldn't the ultrasonic vibration transmitted through the frame or the the sidewall of the tube?
[ANS]Not impact, this is common use case.
Thanks!
Best Regards
Johnson
Hi Johnson,
Thanks for your reply. I have since improved the noise level and managed to get a better waveform (lower the initial DC offset ) with lower gain, down from 30.8 dB to 15.5dB.
I am considering using the design from MSP430FR6043 EVM below and implement it on the MSP430FT6047 on my new prototype 
If I were to use the same IO
P6.7 - RxEn
P3.6 - RxSel1
P3.7 - RXSel2
And
May I know if I am able to use external driver like 6043 on the 6047 Flow flow meter.
Bump
Johnson,
Thanks . Can I expect similar performance in terms of resolution of dTOF if using the FR6043.
FYI, after i've dialed down on the Gain from 30.8 to 15.5 , the noise level has improved by leaps and bound. However, I am still looking for ways to further improve it . WIll FR6043 be a good choice or I have not extracted the most out of the FR6047. Your advice is very much appreciated
