•Brochure: FCM2000 Coriolis Mass Flowmeter
ABB Mass Flowmeters operate according to the Coriolis principle. FCM2000 with the classical parallel meter tubes features:
- Space saving sturdy design
- Wide meter size range
- Price advantages for the customer
- Digital Signal Processing (DSP)
- Insensitive to pipeline stresses and vibrations
- Self draining in both horizontal and vertical orientations
- Straight forward installations
- Two configurable current output for mass flowrate, volume flowrate, density or a pulse output
Measurement Principle
When a mass flows through a vibrating tube Coriolis
forces are generated which bend or twist the tube.
The extremely small tube displacements are detected
by optimally positioned sensors and evaluated
electronically. Since the measured phase shift of the
sensor signals is proportional to the mass flowrate the
Coriolis Mass Flowmeter measures the mass flowrate
directly. The measurement principle is independent
of the density, temperature, viscosity, pressure or
conductivity. The meter tubes always vibrate at their
natural frequency which is a function not only of the
meter tube geometry and the meter tube material
properties but also the mass of the fluid in the vibrating
meter tubes. This frequency provides exact information
about the density of the fluid being measured.
In summary, the Coriolis Mass Flowmeter can be used
to simultaneously measure the mass flowrate, density
and temperature.
The Modular Concept
The basic concept is to effectively combine the flowmeter
primary and the converter. The wide measuring
ranges and the large variety of process connection
types and meter tube materials coupled with the
customized software, "Standard Flowrate" , "High
Accuracy Density Measurements" assure an optimum
adaptation to existing process requirements.
