Gas flow meters

The metrological service of an enterprise is often tasked with controlling and measuring gas consumption during the operation of a gas distribution station or gas supply system with different performance levels. For this purpose, a special device is used - an industrial gas flow meter, which allows to determine physical and chemical parameters and thermophysical parameters of mixtures utilization by means of direct measurement.

Peculiarities of gas flow measurement in production.

Regular or continuous monitoring of natural gas, petroleum gas, sulphur dioxide, propane, nitrogen, acetylene, methane, oxygen or other mixtures ensures that industrial facilities are brought up to standard in a timely manner and that people and the environment are safe.

To determine the value using meters - flow meters to calculate gas wastes, complex metering is used, which is a combination of several types of meters:

• calculators;
• sensors;
• resistance thermocouples.

Types of industrial flow meters and meter measurement methods

Measuring the flow of gases is an important and complex task. Since all technological processes have different requirements for measuring equipment, gas flowmeters are purchased according to the specifics of production and measurement methods.

The types of equipment produced by modern manufacturers are several:

• Rotary. Mechanical flow meters in which the meter records the number of rotor revolutions, with their further conversion into volume values.
• Turbine. Meters are characterized by the presence of flow rectifiers. The readings of gas flow meters are determined with the help of counters of the magnetic kind (rotation speeds depend on how intense the gas flows are).
• Vortex. Have special elements that create frequencies of air oscillations, which are detected by sensors. They measure both the intensity of gas flows and the flow rate.
• Ultrasonic. Non-contact meters for installation outside pipelines. The principle of operation of such gas flow meters in the pipeline is based on the differences in velocities of ultrasonic radiation. The main elements of gas flow meters are sensors located relative to the flows at an angle of 45 degrees. The electronics of the meters calculates the indicators accurately, using the characteristics of the pipelines and the difference in gas pressure and velocity.

Advantages of ultrasonic meters

Ultrasonic flow meters are among the most reliable and accurate. The difference from the others:

• easy installation and maintenance;
• high metrological characteristics;
• self-diagnostic functionality (electronics performs checks in constant mode);
• flowmeters operate at high pressure;
• possibility to measure gas flows with different velocities.
