ME2200 Coriolis mass flow meter is a device used to measure the mass flow rate of a fluid, such as water or oil, flowing through a pipe. The meter is based on the Coriolis effect, which states that a moving object or fluid will have its path curved when it passes through a rotating frame of reference. Mechelex Instruments Coriolis mass flow meter uses this effect to measure the mass flow rate of a fluid by measuring the force of the fluid on the rotating frame of reference. The meter then uses this force to calculate the mass flow rate of the fluid.
