The Correflow MFM® (Mass Flow Monitor) is the only in-line, real-time system to measure velocity, concentration, and mass flow of each component in various two-phase mixtures. The system measures gas, solid, or non-conducting liquid in nearly any combination of two materials, (this includes solids in insulating liquids, solids in gas, gas in insulating liquids, and miscible insulating liquids). In many process streams, the MFM is the only way to accurately monitor actual feed rates. The MFM provides direct measurement of stream concentration and mass flow, allowing closed-loop process control. Unlike other systems, the MFM can measure pulsed flows, as well as continuous streams, with varying concentrations in real-time. Other instruments measure only the mass flow of the slurry, not the individual components, and erroneously assume that the slurry concentration is always constant.
The Correflow MFM combines the technology of two patented measurement techniques (velocity and concentration) in a single sensor to achieve a measurement of mass flow. The first measurement determines the two phase slurry velocity and the second measurement determines the fraction of one of the phases of the mixture in relation to the other. Combining these two parameters yields mass per unit time (ie. mass flow).
