GeneralThe flow rate of all liquids, slurries and sludges as well as oils, fats, dyes, suspensions, chocolate, butter, bases, Tenside, two phase fluids etc. can be metered with the TRIO-MASS and TRU-MASS flowmeters independent of their electrical conductivity, density, pressure or temperature. The metering system measures the mass, density and temperature of the fluid simultaneously. The me-tering system consists of a flowmeter primary and a converter mounted in a field mount housing or a 19"-Insert.
The Modular ConceptThe basic concept was to effectively combine the flowmeter primary and converter. A wide range of meter sizes, a variety of flow loop materials and process connections as well as specializing on flow, density or batching operations results in optimal adaptation to existing process conditions.

Mass Flowmeter
The ABB-Mass Flowmeters TRU- and TRIO-MASS are character-ized by the following design features:
• The flow loop is formed from a single tube without any joints.• Straight through flow with minimal pressure drop.• Insensitive to pipe line vibrations and stresses.• Extended meter life is assured by minimizing tube stresses and
thick wall sections.• Good long term stability.• Special in- and outlet sections are not required (arbitrary
installation orientations). • Independent of flow profile.• Self draining when installed in vertical and horizontal
orientations.• 180 °C fluid temperature.• No electronic assemblies in the flowmeter primary.• Stainless steel flowmeter primary.• µP-controlled converter with keypad entry of process
parameters.• Backlit 2 line LCD display.• Current outputs user configurable for indication of mass, densi-
ty, volume or temperature.• Converter design (FILL-MASS) includes software for fast batch
operations.• Converter design (DENSI-MASS) for high accuracy density
measurements; concentration, calculation of solids content, Brix etc.
• Communication capable on serial data link or HART®-Protoco or Profibus DPl.
• Pulse output active or optocoupler, galvanically isolated• Ex-design: TÜV 99 ATEX 1388X

• Food industry design with sanitary coupling or Tri-Clamp con-nections.
• Maximum cable length between flowmeter primary and converter 300 m.
Principle of OperationWhen masses flow through a vibrating pipe, Coriolis forces are generated which bend and twist the pipe. These very small pipe de-formations are measured by optimally mounted sensors and elec-tronically evaluated. Because the measured phase shift of the sensor signals is proportional to the mass flowrate, the Coriolis Mass Flometer measures the mass flowrate in the flowmeter direct-ly. The metering principle is dependent of the density, temperature, viscosity, pressure and conductivity.
The metering tubes always vibrate at resonance. The resonant fre-quency during operation is a function of the meter tube geometry, the material characteristics of the flowmeter and the mass of the fluid in the metering tube which is also vibrating. It provides an ac-curate measure of the density of the fluid being metered. In sum-mary, it is possible to simultaneously measure the mass flowrate, fluid density and temperature with the Coriolis Mass Flowmeter.

System Design
TRIO-MASShe flowmeter primary consists of two one piece, formed meter tubes oriented in parallel. A twist and bend resistant mounting structure which connects the in- and outlet of the flowmeter is es-pecially designed to isolate the meter tube from external forces and moments.
The in- and outlet ends of the meter tube are welded to flow split-ters. Therefore there is no direct connection to the process connections. This approach minimizes the effects of external vibra-tions on the measurements.
Long life is assured by elimination of weld seams in the highly stressed areas and by hard silver soldering under vacuum the mounts for the meter tube , driver and sensor. Exceptional long term stability is assured by the vacuum stress relieving of the meter tubes.
Straightforward installations, wide flow ranges and a variety pro-cess connections and last but not least, the quick amortization of the costs make the TRIO-MASS an instrument which can be opti-mally applied in production processes.
TRU-MASSWith the TRU-MASS sensor two identically-formed screw-shaped measuring pipes are electromagnetically oscillated to their reso-nance frequency. The corolis forces that occur when flow takes place through the medium, cause a slight deviation in flow rate, which is linearly dependent on the measurement pipes to an oscil-lation axis (vertically standing) standing upright to the measure-ment axis that forces and overlays the pipe movement by the exciter. This movement is traced by two speed sensors and is then electronically evaluated.

Assembly and Installation
InspectionBefore installing the flowmeter primary, check for mechanical dam-age due to possible improper handling during shipment. All claims for damage are to be made promptly to the shipper prior to install-ing the meter.Installation Requirements/Design InformationThe TRIO-MASS and TRU-MASS are suitable for in- or outdoor in-stallations. The standard instrument meets the requirements of Protection Class IP67. The flowmeter primaries are bidirectional and can be installed in any orientation (vertical or horizontal), as long as the meter tubes are always completely filled with fluid. The corrosion resistance of fluid wetted parts must be considered.
The following points are to be considered during installation:The preferred flow direction is indicated by the arrow on the flow-meter primary. Flow in this direction will be indicated as positive (a forward/reverse flow calibration is available as on option).
Installation Orientation• The TRIO-/TRU-MASS operates in all orientations. The optimal
installation orientation is vertical with the flow upwards.
Supports• In order the support the weight of the flowmeter primary and to
assure a correct measurement when external effects are present (e.g. vibrations) the flowmeter should be installed in a rigid pipeline. Two brackets or hangers should installed sym-metrically and stress free in close proximity to the process connections.
Shut Off Devices• For setting the system zero shut off devices in the pipeline are
required.- downstream for horizontal installations - upstream for vertical installations
• If possible, shut off devices should be installed up- and down-stream of the flowmeter primary.
Inlet Straight Sections• The Massmeter does not require any flow conditioning
inlet straight sections. Care should be exercised to assure that any valves, gates or 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 density measurement. Therefore the flowmeter primary should not be installed at the highest point in the system. Advantageous are installations in low pipeline sections, at the bottom of a u-section of pipeline.
• Long drop lines downstream from the flowmeter primary should be avoided to prevent the meter tube from draining.
• The connecting pipelines should be axially centered to assure a stress free installation
• The flowmeter primary should not come in contact with any other elements. Mounting the housing is not permissible.
• When the cross-section of the connecting pipeline is larger than the flowmeter primary size, suitable standard reducers can be installed.
• If strong vibrations exist in the pipeline they should be damped using elastic pipeline elements. The damping devices must be installed outside of 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.
• Care should be exercised to assure that any dissolved gases, which are present in many liquids, do not outgas. The minimum 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 or for fluids that boil readily.
• The flowmeter primary should not be installed in the vicinity of strong electromagnetic fields, e.g. near motors, pumps, trans-formers etc.
• Multiple flowmeter primaries in the same pipeline or installed in interconnected pipelines should be located far from one another, or, the pipeline must be decoupled to prevent crosstalk.
Zero Adjustment• In order to adjust the zero under operating conditions it must be
possible to reduce the flowrate „ZERO“ while the meter tube is completely filled. A bypass line is optimal when the process cannot be shut down. It is important for accurate measure-ments that during the adjustment there be absolutely no gas bubbles present in the flowmeter primary. Additional advanta-geous conditions during the zero adjustment are that the oper-ating pressure and operating temperature exist in the meter tube.

Installation Information
Vertical InstallationsThe optimal installation orientation is a vertical installation with an upward flow following Fig. This has the advantage that any solids contained in the fluid will settle downward and gas bubbles will move upward 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
Self Draining Horizontal Installations
Installations in Drop LinesThe installation recommendation shown in following Fig. is only possible if a pipeline reduction or orifice with a smaller cross-sec-tion can be installed to prevent the flowmeter primary from draining during the measurements.
Difficult Installation LocationsThe accumulation of air or gas bubbles in the meter tube can lead to increased inaccuracies. In following Fig. some difficult installations are shown.Installations at the highest point in the system (Figure A) can result in the formation of air pockets which can lead to appreciable inaccuracies.An additional difficult installation is immediately upstream of a free discharge (Figure B) in a drop line.
!Note
Check that the coordination between the flowmeter primary and the converter is correct. The instruments which are to be con-nected together have identical end numbers e.g. X001 and Y001 or X002 and Y002 on the Instrument Tags.
Pressure lossThe resulting pressure loss is a function of the medium character-istics and of the existing flow. For calculation of pressure loss please use the sizing program FLOWCALC.

Converter, FILL-MASS
The Coriolis-Mass-Flowmeter for Fast Batch and Fill OperationsFilling and InjectingThe Coriolis-Mass-Flowmeter can be used for fast fill and batch op-erations through utilization of a special software. Up to 4 different batch quantities with anticipatory and end contacts can be preselected from the converter keypad. For large container filling the fill concept provides for a two stage fill using the anticipatory and end contacts. This reduces overrun quantities
and improves the fill reproducibility. The measurement also incorporates an automatic safety shut off when the maximum fill time is exceeded. In order to utilize very short fill cycles with high accuracy the converter measures and automatically corrects the overrun quantity with a specially designed control algorithm.

The Coriolis Mass-Flowmeter for High Accuracy Density Measurements and Concentration CalculationsThe MFM measures the density of the fluid which fills the meter by utilizing the flow loop resonant frequency. The special density soft-ware makes it possible to indicate in the display and over the cur-rent output the concentration in addition to the density value. As the primary is available with two selectable density calibrations (stan-dard density ± 0.005 kg/dm3, sepcial densisty ± 0.001 kg/dm3), dif-ferences in the accuracy of the concentration measurement result. Another influence to the accuracy of the concentration measure-ment is the measuring effect, which results of the change of densi-ty.
The concentration calculation is made using the values of the en-tered data pairs (density -concentration). Values for two density-concentration curves can be entered.
It is also possible to calculate the product quantity from the mass flowrate and concentration and to output the concentration mass flowrate in addition to the total mass flowrate.
