Multitube Assemblies

Gas Proportioners

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 rotameters. 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

Qa = Qg x [G x (Ta/T0) x (P0/Pa)]1/2

where:

Qa = equivalent air flow scale reading at Standard Conditions

Qg = true flow of metered gas

G = specific gravity of metered gas

Ta = absolute temperature at flow conditions (Kelvin or Rankine)

T0 = absolute temperature at standard conditions (294 K or 530°R)

Pa = pressure at flow conditions (psia)

P0 = pressure at Standard Conditions (14.7 psia)

LIQUID

Qw = QL x [(df - dw)/(df - dL)) x (dL/dw)]1/2

where:

Qw = equivalent water flow capacity at Standard Conditions

QL = max flow of metered liquid

df = 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

dL = density of metered liquid, g/ml

dw = density of water at Standard Conditions (1.0 g/ml)
