What type of flow measurement is typically used to monitor vapor recovery?

Mass flow measurement is commonly employed in monitoring vapor recovery systems. This approach is advantageous because it provides a precise measure of the actual mass of vapor being recovered, which is essential for compliance with environmental regulations and for optimizing the efficiency of the recovery process. Unlike volume flow measurement, which might be affected by changes in temperature and pressure, mass flow measurement delivers a more stable and accurate representation of the vapor flow, irrespective of these conditions.

In vapor recovery systems, understanding the total mass of vapor ensures that the system operates efficiently and minimizes the release of pollutants into the environment. This makes mass flow measurement particularly crucial, as it aids in verifying that the vapor recovery system meets the required performance standards and regulatory compliance.

While other types of flow measurements, such as volume, velocity, and standard flow measurement, have their own applications, they do not provide the same level of accuracy for the specific requirements of vapor recovery processes, particularly when the gas composition can vary significantly.
