Answer / rajkumar

The height of column doesn't
matters here. You have to fix
the range in approximate
estimation of maxim pressure
drop. For example the
heighest d. pressure will be
the equal to inlet pressure.
So you can set this also a
range.

Answer / sateesh kumar singh

If you want to mesure a differential pressure of Packed
distillation Column and currect out put signal then
instrument mesuring rang should be higher than required
measuring renge.

URV >3000 mmm WC ( Say 4000 mm WC)
LRV= 0 mm WC

calibrate it 0 mm WC to 4000 mm WC .

Is This Answer Correct ?    0 Yes 3 No
