0% liquid level differential pressure
LRV = h×ρ
100% liquid level differential pressure
URV = l×ρ+h×ρ
= (l+ h)×ρ
Accordingly,
Low limit (LRV): hρ
High limit (URV): (l+ h)ρ
is the range to set.
Calculation example:
ρ: 0.9
l: 1500 mm
h: 250 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
UR = (1500+250)×0.9 = 1575 mm H
2
O = 15.45 kPa
Accordingly,
Low limit (LRV): 2.206 kPa
High limit (URV): 15.45 kPa
is the resulting range.
