Describe the function of a mass flow meter.

The function of a mass flow meter is to accurately measure the mass of a fluid passing through it. This type of flow meter is designed to provide precise readings of the flow rate based on the actual mass of the fluid rather than its volume. This is particularly important in scenarios where fluid density may change due to variations in temperature or pressure, as mass flow meters can deliver consistent and reliable measurements regardless of these conditions.

Mass flow meters are commonly used in various industries, such as chemical processing and food production, where knowing the exact mass of a fluid is critical for efficiency and safety. By focusing on the mass, these meters help ensure that processes are controlled accurately, ultimately contributing to better quality and reduced waste in production. This feature distinguishes mass flow meters from other types of flow measurement devices that may be concerned only with volume, pressure, or temperature.
