A mass flow meter is a device used to measure the mass flow rate of a fluid. It is commonly employed in various industrial applications where accurate measurement of fluid flow is essential. traditional mass flow meters that measure volumetric flow (such as liters per minute) , fluids temperature and pressure to calculate the fluids mass flow, Coriolis mass flow meters directly measure the mass of the fluid passing through the system (such as kilograms per second or ton/h ).
There are different types of mass flow meters, including:
-
1. Coriolis Flow Meters: These meters utilize the Coriolis effect, which is the deflection of a mass moving in a rotating system. The fluid flows through a vibrating tube, and the Coriolis forces acting on the fluid cause a phase shift in the tube's vibration. This phase shift is directly proportional to the mass flow rate.
-
2. Thermal Mass Flow Meters: These meters measure the heat transfer between a heated sensor and the fluid. As the fluid flows past the heated sensor, it carries away some of the heat, and the temperature difference between the sensor and the fluid is used to determine the mass flow rate.
-
3. Differential Pressure Flow Meters: These meters measure the pressure drop across a constriction or obstruction in the flow path. By knowing the pressure drop and the geometry of the flow path, also gas ,air or steam temperature and pressure to calculate fluids density , then mass flow rate can be calculated.
