4 1.2. Aount (of Gas): 2 The aount of Gas n is the nuber of oles of gas. 1ol olecules. For better understanding and its copact atheatical forulation, the properties of gases are described using an idealised odel called ideal gas. The aount of an ideal gas is defined using the ideal gas law: p V n R T J using the universal gas constant R ol K Volues V, pressure p und teperature T are state variables. They are defining the state of the gas aount n. For known coposition of the gas, its aount n can be substituted by its ass p V R i T using Ri als individual gas constant. It is dependent on the coposition of the gas: Gas Air O2 N2 H2 CO2 indiv. Gas constant Ri ,8 296, ,9 Finally the aount of gas can be detected in two different ways: 1. Weighing of the aount easuring the ass of the aount. With known weight of one gas olecule, the aount of gas can be calculated. Mass, easured in kg or g 2. Deterination of the state of the gas: easuring of the volue V. With known teperature T and pressure p, the aount can be caluculated using the ideal gas law. Volue, easured in, d or c The ratio between those two quantities is defining the density ρ. ass kg kg g density ρ,, volue V d c The density is a paraeter of the state of the ediu and is defined by the individual gas constant Ri, teperature and pressure of the ediu. Version 1.0 4/9
5 ρ p R T i The density ρ of the gas is linearly dependent on its pressure p und its teperature T. Deonstrative, that can be shown using a cylinder whose volue can be variated by a oving piston The syste is absolutely leak proof, aount and ass of the filled ediu is constant. To increase the pressure inside the cylinder the piston is pressed downwards (p2>p1), the gas is copressed, the density of the gas is increasing, the volue is decreasing. On the other hand, by heating the gas inside the cylinder (T>T1), the density of the gas is decreasing and the volue is increasing! Suary: The ass of a gas with known coposition is a direct easure for its aount. The volue is just defining the aount of a gas in cobination with its teperature and pressure, but is independent fro its coposition! To get a teperature- and pressure independent voluetric-quantity, the easured volue is recalculated to the volue which would be easured at standardized conditions. This standardized volue VStandard is a voluetric quantity independent fro coposition, pressure and teperature of the gas. Standard conditions acc.

The quantities for flow are based on the different quantities for an aount of gas: ass, volue and standard volue Mass flow rate The Mass flow rate is defining the aount of a fluid with known coposition flowing through a surface A in a certain tie-periode.

Voluetric flow rate average velocity flow surface V [ / s] v[ / s] A[ 2 ] To calculate the standard volue flow it is necessary to easure actual pressure and teperature. Standard voluetric flow rate voluetric flow rate at standard conditions V standard [ N / s] V [ / s] p[ bar] 27,15K ( 27,15 + T[ C] ) 1,0125bar With known density of the fluid (Air) at standard conditions it is possible to calculate the ass flow.

9 . Flow easureents using E+E Hotfil aneoeter: The easureent principle of a hot-fil aneoeter is to easure the nuber of olecules which are streaing over the heater sensor, and so conduct heat. With rising air pressure, the density of the gas is increasing and with the sae velocity ore olecules are streaing over the sensor. So, to easure the air velocity of the olecules at any pressure, this pressure influence has to be corrected. At E+E all Air Velocity Transitter are calibrated at Standard Pressure of 1,0125 bar. For diverging air pressures fro 1,0125 bar, that influence has to be corrected. Air velocity: v[ / s] v Transitter 1,0125bar [ / s] p[ bar] The teperature also has a sall influence on the heat transfer fro the sensor. E+E Transitters have ipleented internal teperature copensations to correct that influence. By easuring the average air velocity in a Tube and with known cross section surface A, the volue flow can be calculated. Voluetric flow rate: V [ / s] A[ 2 ] v Transitter 1,0125bar [ / s] p[ bar] In ost industrial applications the voluetric flow rate at standard conditions has to be easured. In that applications the E+E Hotfilsensor and its calibration at standard pressure shows its ain advantages. Because of the opposed pressure influence of sensor and conversion of voluetricflow to standard-voluetric flow, the E+E Hotfil-Sensors easure standard voluetric flow and ass flow independent to pressure.
