ter. Hazardous residues may still be present in the flowmeter and escape when it is opened.
• If pipeline vibrations are present, it is recommended that the flange bolts and nuts be secured to prevent
loosening.
• Within the framework of operator responsibilities, perform a regular periodic inspection to check:
– flowmeter operation
– seal integrity
– wear (corrosion, abrasion, cavitation)

2 Principle of Operation

2 Principle of Operation
The ABB Automation Products Mass Flowmeter operation is based on the Coriolis principle. The FCM2000
construction uses the classical parallel meter pipes and is characterized, in particular, by a space saving and
rugged design, a wide flowmeter size spectrum at an advantageous price to the customer.
When a mass flows through a vibrating pipe, Coriolis forces are generated which bend and twist the pipe.
These very small pipe deformations are measured by optimally mounted sensors and electronically evaluat-
ed. Because the measured phase shift of the sensor signals is proportional to the mass flowrate, the Coriolis
Mass Flowmeter measures the mass flowrate in the flowmeter directly. The metering principle is independent
of the density, temperature, viscosity, pressure and conductivity of the fluid.
The meter tubes always vibrate at resonance. This resonant frequency, at the operating conditions, is a func-
tion of the meter tube geometry, the characteristics of the flowmeter materials and the mass of the fluid in
the meter tube, which is also vibrating. It provides an accurate measure of the density of the fluid being me-
tered.
An integrated temperature sensor measures the fluid temperature and is utilized for corrections to temper-
ature dependent instrument parameters. Summarizing, it is possible to simultaneously measure the mass
flowrate, fluid density and temperature with the Coriolis Mass Flowmeter. Other measurement values can be
derived from these values, e.g. volume flowrate or concentration.

4.1 Installation and Maintenance, Flowmeter Primary
4.1.1 Inspection
Before installing the flowmeter primary, check for physical damage due to possible improper handling during
shipment. All claims for damage are to be made promptly to the shipper.
4.1.1.1 Installation Requirements/System Sizing Information
The FCM2000 is suitable for both in- and outdoor installations. The standard instrument meets the require-
ments of Protection Class IP 67. The primary is bidirectional and can be installed in any orientation. It is im-
portant to assure that the meter pipes are always completely filled with fluid. The corrosion resistance of the
fluid wetted materials must be evaluated.
The following points are to be considered during installation:
The preferred flow direction is indicated by the arrow on the flowmeter primary. Flow in this direction will be
indicated as positive (a forward/reverse flow calibration is available as on option).
Installation Orientation
• The FCM2000 operates in any orientation. The optimal installation orientation is vertical with the flow
upwards.
Supports
• In order to support the weight of the flowmeter primary and to assure reliable measurements when
adverse external effects exist (e.g. vibrations), the primary should be installed in rigid pipelines. Two sup-
ports or hangers should be installed symmetrically and stress free in close proximity to the in- and outlet
process connections.
Shut Off Devices
• To conduct a system zero adjustment, shut off devices are required in the pipeline.
- in horizontal installations at the outlet
- in vertical installations at the inlet
• When possible, shut off devices should be installed both up- and downstream from the flowmeter pri-
mary.
Inlet Straight Sections
• The FCM2000 does not require any flow conditioning inlet straight sections. Care should be exercised
to assure that any valves, gates, sight glasses etc. do not cavitate and are not set into vibration by the
flowmeter primary.
System Design Information
• The presence of gas bubbles in the fluid can result in erroneous measurements, particularly in the den-
sity measurement. Therefore the flowmeter primary should not be installed at the highest point in the
system. Advantageous are installations in low pipeline sections, e.g. at the bottom of a U-section in the
pipeline (invert).
• Long drop lines downstream from the flowmeter primary should be avoided to prevent the meter tube
from draining.
• The connection pipelines should be of a suitable length and should not have any appreciable axial dis-
placement so that the flowmeter primary can be installed in a stress free manner.
• The flowmeter primary should not come in contact with any other objects. Attachments to the housing
are not permissible.
• When the cross-section of the connecting pipeline is larger than the flowmeter primary size, suitable
standard reducers should be installed.

16 FCM2000 D184B111U02
• If strong vibrations exist in the pipeline, they should be damped using elastic pipeline elements. The
damping devices must be installed beyond the supported flowmeter section and outside of the section
between the shut off devices. The direct connection of flexible elements to the flowmeter primary should
be avoided.
• Cavitation should be avoided, because the vibration of the meter pipes could be affected. Cavitation
can be eliminated by increasing the system pressure.
• Care should be exercised to assure that any dissolved gases, which may be present in many liquids, do
not outgas.
The back pressure at the outlet should be at least 0.2 bar.
• Assure that operation below the vapor pressure cannot occur when a vacuum exists in the meter tube.
• The flowmeter primary should not be installed in the vicinity of strong electromagnetic fields, e.g. near
motors, pumps, transformers etc.
• When operating more than one meter in one or multiple interconnected pipelines, the flowmeter prima-
ries should be spaced distant from each other or the pipelines should be decoupled to prevent cross
talk.
• The instrument should be protected from direct sunlight.
If the density is to be measured to the highest precision with the FCM2000 (expanded density calibration
±0.001 kg/l), the flowmeter primary should be insulated (see Fig. 38 on Page 82).
4.1.1.2 Zero Adjustment
In order to adjust the zero under operating conditions it must be possible to reduce the flowrate „ZERO“
while the meter tube remains completely filled. A bypass line is optimal when the process cannot be shut
down. It is important for accurate measurements that during the zero adjustment there are no gas bubbles
in the flowmeter primary. It is also important that the pressure and temperature in the meter tube be the same
as those which exists during operation.

4.1.1.3 Installation Instructions
Vertical Installations
The optimal installation orientation is a vertical installation with an upward flow as shown in Fig. 6. This has
the advantage that any solids contained in the fluid will settle downward and any gas bubbles will move up-
ward out of the meter tube when the flowrate is zero. Additionally, it is easy to drain the meter tube. Deposits
can thereby be avoided.

Horizontal Installations
Installation in a Drop Line
The installation recommendation shown in Fig. 8 is only permissible if a pipeline reduction or orifice with a
smaller cross-section can be installed to prevent the flowmeter primary from partially draining during the
measurements.

Difficult Installation Conditions
The accumulation of air or gas bubbles in the meter pipe can lead to increased inaccuracies. Some difficult
installations are shown in Fig. 10.
Installations at the highest point in the pipeline (Figure A) can result in the formation of air pockets which can
lead to appreciable inaccuracies. Another difficult installation condition is immediately upstream of a free dis-
charge (Figure B) in a drop line.

5.1 Installation and Maintenance, Flowmeter Primary
The transport protection screws are installed at the factory in order to prevent damage during shipment. The
converter is a sensitive instrument and must therefore be handled with care.
Pressure Reduction Valve
The pressure values are approximations. An exact specification of the absolute value at which a rupture or
leak occurs is not possible. For operating pressures/fluids, which could possibly cause a meter pipe rupture
with resultant personnel injury, property damage, etc. special protective measures for the sensor installation
are recommended (special arrangements, protection covers, pressure relief valves etc.).
The sensor housing incorporates a 1/8“-nipple. When the nipple is removed, a pressure relief valve can be
installed to automatically block the flow to the sensor in the event of a leak. Installation information may be
found in the Section „Installation of a Pressure Relief Valve“.
!
Attention!
The max. operating pressure for meter sizes DN 3 [1/10”] and DN 6 [1/4”] is 50 bar.
For meter size DN 1.5 [1/16”] the max. pressure is 70 bar.
!
Attention!
Before start-up, both transport protection screws must be removed and replaced by the nipples included
with the shipment as shown in the figure. Before removing the transport protection screws observe the fol-
lowing:
Under no circumstances may humidity, liquids or foreign objects enter the flowmeter primary housing be-
cause the measurement accuracy could be adversely affected.

Important!
Before removing the nipple from the sensor housing the following must be considered:
Under no circumstances may humidity, liquids or foreign objects enter the flowmeter primary housing be-
cause the measurement accuracy could be adversely affected. This type of problem can be avoided by ob-
serving the following instruction:
1. To acclimate the sensor it should be placed in a dry, clean area until it has reached an ambient temper-
ature of approx. 20 °C.
2. Care should be exercised when removing the nipple and installing the pressure relief valve.
3. Assure that the pressure relief valve is correctly installed and properly tightened, so the gasket is seated
correctly. Whenever it is removed the gaskets should be replaced.
