Hi~

Our company is trying to develop a water meter using the MSP430FR6047.

So, I would like to know how to measure Q flow according to the flow measuring tube in EVM430-FR6047.

We are creating a test environment with AudioWell's DN15(HS0014) and DN20(HS0016).

However, I have a question, so I would like to contact you.

In general, it is known that water meters have different Q1 (minimum flow rate), Q2 (transition flow rate), Q3 (maximum flow rate), and Q4 (overload flow rate) for each measuring pipe.

Are the Q1/Q2/Q3/Q4 mentioned above values that can be obtained through calibration?

Or is there an explicitly set value?

To check Q1 and Q3, which test and what value should I check?

Also, how do you calculate the maximum allowable error?

This is my first time developing a water meter, so please explain in detail.

thank you
