ISO 10780: Gas Flow Rate and Volumetric Flow Rate Measurement Standards

Stationary Source Emissions - Measurement of Velocity and Volumetric Flow of Gas Flows in Ducts

ISO 10780

It is an international standard for measuring the flow rate and volumetric flow rate of gases emitted from stationary sources. This standard provides a basic reference for the installation and management of emission monitoring and control systems in industrial and environmental applications. Gas flow rate and volumetric flow measurements are critical for environmental management and regulation of industrial processes.

Purpose and Scope of the Standard

ISO 10780 describes the methods required for the accurate monitoring and assessment of gas emissions from stationary sources. The standard specifies methods that accurately and reproducibly measure gas flow rate and volumetric flow rate. These measurements are used to assess the environmental impact of gas emissions, meet regulatory requirements, and enable energy and efficiency management in industrial processes.

Gas Flow Rate and Volumetric Flow Measurement Methods

ISO 10780 includes various methods used to determine gas flow rate and volumetric flow rate:

Thermal Volumetric Flow Methods: It is based on the principle of calculating the volumetric flow rate of the gas by measuring the temperature and pressure of the gas. Thermal volumetric flowmeters are used in measurements. These devices calculate the flow rate using the temperature and pressure information of the gas.
Electromagnetic Flow Methods: It is based on the principle of measuring the flow rate of gas with the help of a magnetic field. The current flowing through the gas interrupts the magnetic field and this produces an electrical signal and determines the flow rate. It is measured using electromagnetic flowmeters.
Differential Pressure Methods: Based on the principle that the flow rate of gas is calculated by measuring the pressure difference between different points along the pipeline. Measurements are made using diffusers or pre-pipe sets.
Thermal Volumetric Flow Methods: It is based on the principle of measuring the volumetric flow rate of the gas by measuring the temperature and pressure of the gas. Measured using hot wire anemometers or hot film flowmeters.

Application Areas of the Standard

ISO 10780 is used in a wide range of industrial applications:

Power Generation Plants: Monitoring emissions from steam generators and gas turbines.
Chemical Industry: Measurement of gas emissions from chemical processes and reactors.
Waste Incineration Plants: Monitoring of gases generated during waste incineration.
Metal Industry: Control of gas emissions from metal processing.
Drinking water and wastewater treatment plants: Measurement of gas emissions from treatment systems.
