Answer / mangesh

LRV=-3000mm water column
URV=0mm water column

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 / vishal khalasi

o to 76.2 mmH2o that is the correct range...

Answer / jaspreet grewal

URV = 0 mm WC
LRV = -3000 mm WC

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 .
