The CORIMASS Measuring System
The CORIMASS Measuring System uses the Coriolis principle for measuring the mass flow
rate of fluids with high accuracy.
When using this measuring principle, it is possible to measure the mass flow rate directly,
independent of any other parameters of the fluid, such as density, temperature, pressure,
viscosity, conductivity and flow profile. Homogeneously distributed small solid particles
(slurries) and gas bubbles have no noticeable effect on the measuring accuracy.
The CORIMASS mass flow rate system is of modular type design, comprising a transducer
and a converter. In the compact version MFM 2081 K / MFM 3081 K the converter is mounted
directly to the transducer; in the separate version MFM 2081 / MFM 3081 the transducer MFS
2000 / MFS 3000 and the converter MFC 081 F are connected to each other via a shielded
multi-conductor cable (figure 1). The MFM 2081 is also referred to as “P-Series,” and the
MFM 3081 is also referred to as “E-Series”. The measurement values of mass flow rate, total
mass and density are available.
Additional to the standard system for special requirements the following models are available:
−
transducer with electric or liquid heating
−
transducer with secondary containment or pressure relief
−
hazardous duty model:
EEx ib II B or EEx ib II C (no electric heating!) are applied
−
FM Class I, II, III, Div. 1 and Div. 2, Groups B-G (pending)
