Calculation example:
ρ: 0.9
ρ
0
: 0.935 (general-purpose remote)
l: 1500 mm
h: 250 mm
d: 2000 mm
would result in:
0% liquid level differential pressure
LRV = (250×0.9) - (2000×0.935)
= -1645 mm H
2
O = -16.13 kPa
100% liquid level differential pressure
URV = (1500+250)×0.9 - (2000×0.935)
= -295 mm H
2
O = -2.893 kPa
Accordingly,
Low limit (LRV): -16.13 kPa
High limit (URV): -2.893 kPa
is the resulting range.
