Series 830/840/860 Instruction ManualAppendix ACalculating For a Single GasThe following tables provide K-factors and thermodynamic propertiesof gases commonly used with mass flow meters and controllers.The purpose of these tables is two-fold:1. Calibrating an “actual” gas with a reference gas. This is particularlyuseful if the actual gas is not a common gas or if it istoxic, flammable, corrosive, etc.2. Interpreting the reading of a flow meter or flow controllerwhich has been calibrated with a gas other than the actual gas.In applying the tables, the following fundamental relationship is used:Where:Q 1 /Q 2 = K 1 /K 2 (1)Q =The volumetric flow rate of the gas referenced to standardconditions of 0°C and 760 mm Hg (sccm or slm),K = The K-factor defined in equation (6),( ) 1 = Refers to the “actual” gas, and( ) 2 = Refers to the “reference” gas.The K-factor is derived from the first law of thermodynamics appliedto the sensor tube, as described in Chapter 1:H =mC•p !T(2)NIM-83/84/86-H A-3
