Part Number: MSP430FR6043

Tool/software:

Hello All,

We are Designing Water meter product for our client. We have selected mspfr6043 for measuring the flow rate .

We referred uss library water demo for the same chip and try to analysis the working of application.

Based on the application design. We have some mandatory requirements as below based on requirement of client.

1. Water Leakage Detection

2. Backflow detection

3. Empty pipe detection

4. Broken Pipe Detection.

5. Air bubble Detection

Is there any method ,ref code or Document reference which can be used to fulfill above features?

Any help will greatly appreciated.

Thanks & Regards,

Hi,

TI does not have reference code for those functions. Usually, customer develop their own function based on the ADC capture data. Customer can reach those data and implement their own algorithm to achieve these functions.

Hi Cash Hao11

Thanks for your response.

We have below Question

1. Is there any section on uss library code or any rough idea that how we can implement those features?

2.The measurement from uss library i.e tof is based on ISR or polling?

Hi,

There are two major functions in the USS library. One is called USS_startLowPowerUltrasonicCapture(), this function will get the ADC capture signal. So, some of your functions based on ADC capture signal can be called after this function. And the other one is called USS_runAlgorithmsFixedPoint(), this function calculates the TOF, volume result. You can add backflow and leakage detection based on the TOF result after this function.

Best regards,

Hi Cash Hao11 ,

Thanks for the help.

1. The USS_runAlgorithmsFixedPoint() will give the dtof ,tof and flow rate and after this API With this 3 parameters(dtof ,tof and flow rate ) can be used to develop the above features. Correct?

2. USS_runAlgorithmsFixedPoint() will be give raw data of dtof ,tof and flow rate or after any post processed data ?

Hi,

You are asking for the same function in those two questions.

The USS_runAlgorithmsFixedPoint() calculates the dTOF, absTOF and flow rate in this API.

The USS_startLowPowerUltrasonicCapture() generates excitation signal and uses ADC to capture the receive. So, you will get raw ADC capture data after this function.

Hi Cash Hao11 ,

The USS_startLowPowerUltrasonicCapture is based on interrupt or polling? As we have other operation to be performed without missing the signal capturing and processing.

Thanks & Regards,

Hi,

They all based on polling.

Hi Cash Hao11 ,

Thanks for quick reply.

Can it be done in Interrupt based? Specifically the measurement mechanism .

Thanks & Regards,

Hi,

I do not think so. Customer need to call the APIs to run the function.
