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.

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

calibrate it 0 mm WC to 4000 mm WC .
