Gases, Mass, and Volume

1. Gases contain a mass and volumes that can be measured depend on temperature of gas. As temperature raises or reduces, volume of gas will very, however mass of gas elements will remain same. This mass is referred to as “molecular mass” and stays same despite of temperature of gas or pressure that has built up in it.

Parts of a Gas Flow Meter

2. A mass flow meter has a sensor tube and a monitoring part. Sensor tube has a metal coil that can be heated to raise temperature of gas passing through it and a sensor which can detect either volume of gas or its molecular mass. The data composed by sensor tube is shown on gauges of monitoring part or on PC that is attached to system.

Measuring Gas Flow

3. To measure flow of a gas, it is sent through sensor tube of a mass flow meter. The heating coil raises temperature of gas, causing its volume to rise also. The temperature is increased to a point set by flow meter's operator, usually a temperature at which volume and mass of gas below usual states is recognized. The sensor of tube starts reading volume of gas as it passes through to decide its volume or molecular mass. The concentration of gas atoms in volume shows how much actual gas is flowing through system, with a higher concentration indicating huge amount of gas per volume.

Monitoring Total Gas Usage

4. Extra parts can be attached to a mass flow meter to measure extra data like total amount of gas that is utilized over a period of time. This can be helpful in monitoring gas usage, as a standard mass flow meter is able to specify amount being utilized at present time.
