Thermal Mass Flow Meters

A Thermal Mass Flow Meter is an electronic device used to measure the mass flow rate of gases in a process system based on the thermal properties of the gas. They typically consist of two temperature sensors, one upstream and one downstream of a heated element, and a signal processor that calculates the mass flow rate based on the temperature difference and the power required to maintain the temperature of the heated element. Thermal Mass Flow Meters can be configured for different gas types, flow ranges, and accuracies, and can also include other features such as temperature compensation, flow totalization, and communication with other devices or systems. Thermal Mass Flow Meters are commonly used in industries such as semiconductor manufacturing, biotechnology, and environmental monitoring, where precise and reliable gas flow measurement is critical for process control, product quality, and regulatory compliance.
