MFM 6100

Two-Phase Mass Flow Meter

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).

Application

• Maintaining maximum reactor productivity is only one of the concerns addressed by the modem-equipped Correflow unit. The rate at which catalyst is delivered to a reaction is also critical in achieving desired mechanical properties. The MFM System also provides early warning for abnormal operation such as clogged feed lines and empty feed pots. Due to the residence time of the catalyst, controllers without the MFM would not have real-time feedback and would have to wait until the reaction slowed before realizing that there was a problem. The MFM6100 enables closed-loop process control to automatically monitor and adjust catalyst flow for maximum reactor efficiency.
