A method for measuring the volume (V) of a gas in a container (1) comprises obturation of the vent(s) (3) of the container and then introduction or withdrawal of a known gaseous mass flow (dm/dt) into and out of the container (1), respectively. The pressure change (dp/dt) caused...
and a controller (56) including computer device form a system so that the speed of ultrasound signals moving through the gas between the CAAnsdutores can be measured and used in the control to calculate the amount of volume of gas passed through the meter.The signals of ultrasound passes thro...
Bowl of the gas to be measured is intended to a device for measuring the concentration of a gas, composed of several plates connected, in the form of layers, having the following characteristics: a) a bottom plate (1) carries a measuring element (1.4) intended to detect the thermal conduct...

Coalbed gas content measurements are commonly used in mine safety as well as coalbed methane resource assessment and recovery applications. Gas content determination techniques generally fall into two categories: (1) direct methods which actually measure the volume of gas released from a coal sample se...
An apparatus for measuring the flow volume of gases and liquids by measuring the difference, between the voltage drop of an ohmic resistance, heated to measuring temperature and encompassed by the medium to be measured, and a second comparison resistance encompassed by the medium and constituting th...
