Can we use a 10000 Lph Flow Transmitter in 100 LPH flow line to get 20mA O/P by adjusting SPAN ? ..

Answer / carl_ellis

You can do whatever you want to with the span adjustment,
but what do you think the results are going to be?

10000:100 is a 100:1 turndown.

Which flow meter technology that uses an analog adjustable
20mA span has 100:1 turndown?

Which flow meter technology has a HART configurable URV with
a 100:1 turndown?

Flow meter accuracy curves ALWAYS bend exponentially upwards
towards increasing uncertainty as the flow approaches zero
low flow. The lower the flow, the greater uncertainty.

Where do you suppose 100 Lph is on the accuracy curve of a
meter designed for 10000 Lph?
