FLT-40G_FLT-40SA_FLT-40ST_FLT-40C_FLT-40T流量計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)



產品參數

多管組件


氣體比例調節器


本頁所示的流量管可安裝在FL3000、氣體比例FL-1GP系列或多管FL-2AA系列150 mm轉子流量計中。所示流量基于21°C(70°F)和14.7 psia下空氣和水的校準。對于其他流體或條件,以下方程提供粗略的近似值。




氣體


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




哪里:


qa=標準條件下的等效空氣流量標度讀數


Qg=計量氣體的真實流量


g=計量氣體的比重


Ta=流動條件下的絕對溫度(開爾文或朗肯)


t0=標準條件下的絕對溫度(294 K或530°R)


pa=流動條件下的壓力(psia)


p0=標準條件下的壓力(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)
