Tool/software: Code Composer Studio
Hi,
I have a couple of questions regarding acoustic length.
1)Default acoustic length in the code is given as 70.Was the radius of the pipe considered in calculating acoustic length…
Part Number: TIDM-1019 I recently purchased an eval board for the MSP430FR6047 Water Meter. I use transducers from Audiowell (same as those used in documention).
The pipe with transducers is on a testing bench with a flowrate (water) fixed at 500L/h…
Part Number: TIDM-1019 Hi,
While i was calibrating the EVM with default parameters and checked the "adv.calibration table" in waveform tab, I got an error saying that minimum volume flow rate falls outside lowest alpha min.
I am using USS_02_20_00_16…
Part Number: TIDM-1019 Tool/software: Code Composer Studio Hi,
While performing calibration , we obtained a slope and offset that seems to differ from the values that we obtain from manual linear fit.
We did use the same set of points in both cases…
Part Number: MSP430FR6047 Other Parts Discussed in Thread: TIDM-1019 Hello.
We are reviewing development ultrasonic sending water meter using your reference design. (TIDM-1019)
Does ultrasonic sending water meter reference design of TI support temperature…
Part Number: TIDM-1019 Are you planning to update the Ultrasonic Design Center Documentation? There appears to be several new features that are not covered in the documentation on your web site.
Specifically, there are some user parameters that were…
Part Number: TIDM-1019 Hello,
I have a problem. I can't control error factor.
I think I configured good parameter values. Design center shows great result at 2500LPH around 99,99%/
but When measuring at 40LPH with same parameters at 2500LPH, Desing…
Part Number: TIDM-1019 Other Parts Discussed in Thread: MSP430FR6047 I recently purchased an eval board for the MSP430FR6047 Low Cost Water Meter. This board has the MSP430 marked with a REV B sticker. This leads me to believe that this eval board has…
Hi! Can we know if the transducers which you are using are a matched pair? You need to get this from the OEM. Also, I would suggest you to refer this app note for frequently asked queries FAQ on ultrasonic sensing technology for flow metering with MSP430FR604x…
Hi Nicholas, If you are referring to an Ultrasonic Water Metering application, the Flash code size is around 69KB, RAM 5.3KB where as just the library uses 22KB Flash and 4.4KB RAM. All of this is mentioned in the TI Design document - TIDM-1019 Section…
