Mass flow meters are devices used to measure the mass flow rate of a fluid moving through a pipe. They work by determining the amount of mass that passes a specific point in a given time, providing accurate measurements regardless of changes in temperature or pressure. This makes them essential in various industries, including oil and gas, food and beverage, and chemical processing. These meters can operate using different principles, such as Coriolis or thermal methods. By providing precise flow measurements, mass flow meters help improve efficiency, ensure product quality, and facilitate regulatory compliance in industrial processes.
