The MF 5000 (capacitive measurement) is used to determine the mass flow rate of all kinds of bulk solids online, either in pneumatic conveying systems or in free fall. Separately from each other the transport velocity and the product concentration is measured and used to calculate the mass flow rate. Thus, the instrument is independent from changing transport velocities. The device is easy to calibrate and because of the small dimensions also easy to integrate in existing plants. It can be used for smaller up to very high flow rates. Parametrization and display of the measured values is done with the com mu nication unit which has several interfaces for connection to a PLC.
