Calculation example:
ρ: 0.9
ρ
0
: 0.935 (general-purpose remote)
l: 1500 mm
h: 250 mm
d: 500 mm
would result in:
0% liquid level differential pressure
LRV = 250×0.9 = 225 mm H
2
O = 2.206 kPa
100% liquid level differential pressure
URV = (1500+250)×0.9 = 1575 mm H
2
O = 15.45 kPa
Accordingly,
Low limit (URV): 2.206 kPa
High limit (URV): 15.45 kPa
is the resulting range.
