2 Operating Principle The is the economical and uncomplicated BB Mass Flowmeter with the new DSP-converter mounted integral or remote from the flowmeter primary. The compact design reduces the installation and cabling expenses. The flowrate information can be viewed directly at the meter site and the meter can be installed in your system in a more space efficient manner. The operates according to the Coriolis Principle. The design offers the following features: Space saving, rugged design. Wide flow range; meter size D (DN 15 [1/2 ]) to meter size L (DN 150 [6 ]). Variety process connection options. Two separate current outputs for flowrate and density as well as a pulse output. Contact in- and outputs. HRT-Protocol. Ex-pproval: The Ignition Protection Type of the output circuits can be user selected as i or e and is determined by the Ignition Protection Type of the circuits connected. The Ignition Protection Type can be changed after the installation has been completed. The contact outputs can be configured as NMUR-Outputs by the user. llowable fluid temperatures up to 180 C, CIP-capable Lighted, 2-line display with data entry using a Magnet Stick without opening the housing. Certified per EHED Mass Converter with Digital Signal Processor (DSP) The converter for the incorporates a digital signal processor (DSP) with which it is possible to measure the mass flow and density values to the highest precision. The Coriolis sensor signals are immediately converted into digital information without any intermediate analog steps. Excellent long term stability and reliability together with fast signal processing are achieved with the new DSP-Converter. Self diagnostic functions for the flowmeter primary and the converter coupled with absolute zero stability are the essential advantages, which are necessary, if reliance on the measurements is to be assured. The converter provides advantages to the user, especially when mass flowrate is to be metered to the highest accuracy. when the fluid density must be determined. when the components of a recipe are to be mixed together. when metering non-conductive or highly viscous fluids or solids loaded liquids. in batch filling systems. Principle of Operation 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 evaluated. 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 function 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 metered. Summarizing, it is possible to simultaneously measure the mass flowrate, fluid density and temperature with the Coriolis Mass Flowmeter.

3 System Design The flowmeter primary consists of two one piece, formed meter tubes arranged in parallel through which the fluid flows. twist and bend resistant mounting structure, which connects the inand outlet of the flowmeter, is especially designed to isolate the meter tube from external forces and moments. Fig. 2: Parallel Meter Tube Design The meter tubes are welded at their in- and outlet ends to flow splitters. Therefore there is no direct coupling to the process connections. This approach appreciably minimizes the effects of external vibrations 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, drivers and sensors. Exceptional long term stability is assured by vacuum stress relieving the meter tubes. Easy installation, wide flow ranges and a variety of process connections and last, but not least, the quick amortization of the costs make the an instrument which can be optimally applied in production processes.

4 ssembly and Installation Flowmeter Primary Inspection Before installing the flowmeter primary, check for physical damage due to possible improper handling during shipment. ll claims for damage are to be made promptly to the shipper. Installation Requirements/System Design Information The FMC2000 is suitable for both in- and outdoor installations. The standard instrument meets the requirements of Protection Class IP 67. The primary is bidirectional and can be installed in any orientation. It is important to assure that the meter tubes 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 FMC2000 operates in all orientations. 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 supports 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 upand downstream of 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. dvantageous 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 pipelines should be connected in a stress free manner. The flowmeter primary should not come in contact with any other objects. ttachments to the housing are 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 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. 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. ssure 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 meter primaries should be spaced distant from each other or the pipelines should be decoupled to prevent cross talk. Request special installation requirements for meter size L. Inlet Straight Sections The mass flowmeter 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. 4

5 Zero djustment 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. 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. Fig. 4: Zero djustment with a By-Pass Line 5

6 Installation Instructions Vertical Installations The optimal installation orientation is a vertical installation with an upward flow as shown in the following figure. This has the advantage that any solids contained in the fluid will settle downward and any gas bubbles will move upward out of the meter tube when the flowrate is zero. dditionally, it is easy to drain the meter tube. Deposits can thereby be avoided. Installation in a Drop Line The installation recommendation shown in the following figure is only possible if a pipeline reduction or orifice with a smaller crosssection can be installed to prevent the flowmeter primary from partially draining during the measurements.

7 Difficult Installation Locations The accumulation of air or gas bubbles in the meter tube can lead to increased inaccuracies. Some difficult installations are shown in the following figure. Installations at the highest point in the pipeline (Figure ) can result in the formation of air pockets which can lead to appreciable inaccuracies. nother difficult installation condition is immediately upstream of a free discharge (Figure B) in a drop line. Figure Figure B Fig. 9: Difficult Installation Conditions Information: Check that the coordination between the flowmeter primary and the converter is correct. The instruments which belong together have the same end characters on the Instrument Tag, e.g., X001 with Y001 or X002 with Y002. Pressure Drop The pressure drop through the instrument is a function of the properties of the fluid and the flowrate. The Selection Program CD-CLC can be used to calculate the pressure drop. 7
