FLT-40G_FLT-40SA_FLT-40ST_FLT-40C_FLT-40T流量计OMEGA

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)

多管组件


气体比例调节器


本页所示的流量管可安装在FL3000、气体比例FL-1GP系列或多管FL-2AA系列150 mm转子流量计中。所示流量基于21°C(70°F)和14.7 psia下空气和水的校准。对于其他流体或条件,以下方程提供粗略的近似值。




气体


qa=qg x[g x(ta/t0)x(p0/pa)]1/2




哪里:


qa=标准条件下的等效空气流量标度读数


Qg=计量气体的真实流量


g=计量气体的比重


Ta=流动条件下的绝对温度(开尔文或朗肯)


t0=标准条件下的绝对温度(294 K或530°R)


pa=流动条件下的压力(psia)


p0=标准条件下的压力(14.7 psia)

   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)

(note: does not include viscosity effect)
