Small-signal rejection problem
Thread Content
The issue of small-signal rejection in flowmeters: for example, if 10t of flow is present and 3t is rejected, before rejection it shows 4t; after small-signal rejection, does it show 1t or 4t?
Hehe, it shows 4t originally; if you set the removal amount to 3t, it still displays 4t. Removal means that when the original value is ≤ 3t, a small portion is cut off and a 0 is displayed, :P
Small-signal clipping means that values below a certain threshold are not displayed (set to zero); generally, however, small-signal clipping occurs within 1% to 5% of the full range!
It displays 4T; after resection, the actual value is shown. It is not displayed when the amount removed is less than that value
Here’s what the poster means: The removal amount is set to 3t; when the flow rate is less than 3t, it is displayed as zero, while when it is 3t or more, the actual measured value is shown. The value of 3t for removal is not used in the subtraction calculations.
It shows 4T; the value displayed after resection is still the actual value. But those below 3t are not displayed
Below that cut-off value, it shows 0
It’s still 4T; what is displayed is the low flow rate, not the actual value of low flow rate. Values below 3T are not shown
It will not be displayed for values below 3t; it will be displayed normally for values above 3t
Display 4t; when the value is less than 3t, display zero
You need to understand the difference between zero-point resection and linear resection
