Orifice plate adjustable flow meter
Thread Content
What does it mean by the minimum flow limit of a orifice plate, a adjustable flow meter? Is there a teacher who can explain it?
It corresponds to the measurement range of the orifice plate; readings become inaccurate below this range
It is what is commonly referred to as the small-signal cutoff value. If it is below this value, 0 is displayed directly. 15000 is 2.5% of 600000
I would like to ask whether the minimum measurable value is due to uncertainty in measurement or simply cannot be measured. For example, in a range of 2500 with a ratio of 1:7, at what point becomes it impossible to measure?

Below the \"minimum measurement value\" indicates uncertainty in the measurement, with the value being significantly too high. Below the \"minimum measurement value\", it cannot be detected; it can always be detected, but the measured value will be extremely inaccurate. The small-signal removal is too drastic; it’s like castrating someone by removing their testicles. :Lol, with too many eunuchs, the social atmosphere becomes messed up, and even the urine basins are weird. A suitable value can be found near the \"minimum measurement value\" and used as a threshold; for values below this threshold, instead of taking the square root, linear truncation should be used. This way, at low flow rates, there will be no mismeasurement, and better measurement accuracy can be achieved.
