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).
Two Component Concentrations: 1% to 99%
Materials: Insulating liquids, solids (particulate), gas (bubbles or as carrier)
Typical Response Time: Concentration–updated at 2.5 millisecond intervals using last measured velocity; Velocity–typically updated once per second
Purge Option: Type Z purged (NEMA 4X): Cl1, Div 2, GR C&D
European (Eex approved) housing also available
Sensor: Typical Sensor Pipe sizes: 1/8” (.32 cm) ID or greater
Pressure limits: 1000 psi (69 bar) typical for small sensors, Higher pressure designs available. No moving parts, no flow restrictions or additional pressure drop
Power Requirements: 115 to 240 VAC, 50 to 60 Hz (100 Watts maximum)
Instrument air for optional pressurization(intermittently 4 scfm @ 80 to 120 psi)
Data Analysis Velocity, volume fraction, mass fraction, mass flow measurements on an instantaneous basis and averaged over user programmed time intervals, Total mass for fixed time intervals, Stream temperature
