Your questions, our prompt answers.

The flow tubes shown on this page can be installed into the FL3000, gas proportioning FL-1GP Series or multiple tube FL-2AA Series 150 mm Variable Area Flow Meters. Flow capacities shown are based on calibrations with air and water at 21°C (70°F) and 14.7 psia. For other fluids or conditions, the following equations provide rough approximations.

GAS
Q_a = Q_g x [G x (T_a/T₀) x (P₀/P_a)]^1/2

where:
Q_a = equivalent air flow scale reading at Standard Conditions
Q_g = true flow of metered gas
G = specific gravity of metered gas
T_a = absolute temperature at flow conditions (Kelvin or Rankine)
T₀ = absolute temperature at standard conditions (294 K or 530°R)
P_a = pressure at flow conditions (psia)
P₀ = pressure at Standard Conditions (14.7 psia)

LIQUID
Q_w = Q_L x [(d_f – d_w)/(d_f – d_L)) x (d_L/d_w)]^1/2

where:
Q_w = equivalent water flow capacity at Standard Conditions
Q_L = max flow of metered liquid
d_f = density of float selected
   Glass: 2.53 g/ml
   Sapphire: 3.98 g/ml
   Stainless Steel: 8.04 g/ml
   Carboloy: 14.98 g/ml
   Tantalum: 16.58 g/ml
d_L = density of metered liquid, g/ml
d_w = density of water at Standard Conditions (1.0 g/ml)
(note: does not include viscosity effect)
