Definitions
- This invention relates to Coriolis flowmeters. More particularly, this invention relates reducing a flag dimension of a Coriolis flowmeter by using flow tubes having a substantially semicircular arc and one set of brace bars. Still more particularly, this invention relates to a configuration of components that maintains zero stability and reduces the amplitude of the vibrating flow tubes to reduce stress applied to the brace bars.
- Coriolis effect mass flowmeters to measure mass flow and other information of materials flowing through a pipeline as disclosed in U.S. Patent Nos. 4,491 ,025 issued to J.E. Smith, et al. of January 1 , 1985 and Re. 31 ,450 to J.E. Smith of February 11 , 1982.
- These flowmeters have one or more flow tubes of a curved configuration.
- Each flow tube configuration in a Coriolis mass flowmeter has a set of natural vibration modes, which may be of a simple bending torsional, or coupled type.
- Each flow tube is driven to oscillate at resonance in one of these natural modes.
- the natural vibration modes of the vibrating, material filled system are defined in part by the combined mass of the flow tubes and the material within the flow tubes. Material flows into the flowmeter from a connected pipeline on the inlet side of the flowmeter. The material is then directed through the flow tube or flow tubes and exits the flowmeter to a pipeline connected on the outlet side.
- a driver applies a force to the flow tube in order to cause the flow tubes to oscillate in a desired mode of vibration.
- the desired mode of vibration is a first out of phase bending mode.
- all points along a flow tube oscillate with an identical phase.
- Coriolis accelerations cause each point along the flow tube to have a different phase with respect to other points along the flow tube.
- the phase on the inlet side of the flow tube lags the driver, while the phase on the outlet side leads the driver.
- Sensors are placed on the flow tube to produce sinusoidal signals representative of the motion of the flow tube.
- the phase difference between the two sensor signals is proportional to the mass flow rate of the material flowing through the flow tube or flow tubes. Electronic components connected to the sensor then use the phase difference and frequencies of the signals to a determine mass flow rate and other properties of the material.
- Coriolis flowmeters have over other mass flow measurement devices is that flowmeters typically have less than 0.1 % error in the calculated mass flow rates of a material.
- Other conventional types of mass flow measurement devices such as orifice, turbine, and vortex flowmeters, typically have 0.5% or greater errors in flow rate measurements.
- Coriolis mass flowmeters have greater accuracy than the other types of mass flow rate devices, the Coriolis flowmeters are also more expensive to produce. Users of flowmeters often choose the less expensive types of flowmeters preferring to save cost over accuracy.
- Coriolis flowmeters that are less expensive to manufacture and determines mass flow rate with an accuracy that is within .5% of the actual mass flow rate in order to produce a product that is competitive with other mass flow rate measurement devices.
- One reason that Coriolis meters are more expensive than other devices is the need for components that reduce the number of unwanted vibrations applied to the flow tubes.
- One such component is a manifold which affixes the flow tubes to a pipeline. In a dual tube Coriolis flowmeter, the manifold also splits the flow of material received from a pipeline into two separate flows and directs the flows into separate flow tubes.
- a manifold In order to reduce the vibrations caused by outside sources, such as a pump, that are connected to the pipeline, a manifold must have a stiffness that is sufficient enough to absorb the vibrations. Most conventional manifolds are made of cast metal in orderto have a sufficient mass. Furthermore, there is a spacer between the manifolds that maintains the spacing between inlet and outlet manifolds. This spacer is also made out of a metal or other stiff material in order prevent outside forces from vibrating the flow tubes. The large amount of metal used to create these castings increases the cost of the flowmeter. However, the elimination of unwanted vibrations greatly increases the accuracy of the flowmeters.
- flag dimension is the length that a flow tube loop extends outward from a pipeline.
- the above and other problems are solved and an advance in the art is made by the provision of a Coriolis flowmeter having a reduced flag dimension in the present invention.
- the Coriolis flowmeter of the present invention has flow tubes that are capable of handling large mass flow rates.
- the Coriolis flowmeter of the present invention does not have a conventional manifold and spacer. Instead, the spacer is substantially surrounds the manifolds. This configuration reduces the cost of the flowmeter.
- the Coriolis flowmeter of the present invention also has a reduced fiag dimension which allows the Coriolis flow meter of the present invention to be used in areas where space is at a premium and it would be impossible to use a conventional Coriolis flowmeter having a conventional flag dimension.
- the flag dimension of the flow tube is reduced by forming the flow tubes in a substantially semicircular arc between inlet ends and outlet ends of the flow tubes.
- the semicircular arc reduces the rise of flow tube to reduce the flag height.
- the entire length of the semicircular arc must vibrate.
- a driver is affixed to the flow tubes at a position along the semicircular arc of each flow tube that is substantially perpendicular to a plane containing the inlet end and the outlet end of the flow tube.
- the driver is positioned at this point to maximize the amount of energy applied to the flow tubes by the driver to cause the flow tubes to oscillate.
- Drive signals are applied to the driver to cause the drive to oscillate the flow tubes at a low amplitude to reduce the stress applied to brace bars affixed to the flow tubes.
- the driver must also drive the flow tubes to vibrate at a frequency that is higher than conventional flow tubes.
- a first brace bar is affixed to the flow tubes proximate the inlet ends and a second brace bar is affixed to the flow tubes proximate the outlet ends.
- Brace bars are metal components that are affixed to each of the flow tubes at substantially the same location along the flow tubes.
- the pick-off sensors In orderto sense Coriolis effect in the oscillating flow tubes, the pick-off sensors have to be affixed to the flow tubes in a position that allows the sensors to detect the greatest amount of Coriolis force at a low amplitude vibration. This allows a lower amplitude vibration to be used in orderto reduce the stress applied to the brace bar.
- An inlet manifold and an outlet manifold may be affixed to the inlet and outlet ends of the flow tube to connect the flow tubes to a pipeline.
- Each manifold is a separate component that is cast separately to reduce the cost of material.
- Each manifold may have a flow path that bends substantially 90 degrees to connect the inlet and outlet ends of the semicircular arc to a pipeline.
- a spacer is affixed to each of the manifolds to maintain the distance between the manifolds.
- the spacer is a structure having fours sides with opposing ends affixed to the inlet and outlet manifolds.
- the spacer encloses a hollow cavity. This reduces the amount of material used in casting the both the manifold and spacer. Openings in the top side of the spacer allow the manifold to connect to the semicircular arc of the flow tubes which protrude outward from the spacer.
- a casing may be affixed to the top side of the spacer to enclose the flow tubes. It is a problem that the casing may resonate a frequency that is close to the frequency of the vibrating flow tubes. This may cause inaccuracies in the readings of properties of material flowing through the flow tube.
- a mass may be affixed to the casing to change the resonant frequency of the case.

- FIG. 3 illustrating a Coriolis flowmeter affixed to a spacer and enclosed in a casing.
- FIG. 1 illustrates a Coriolis flowmeter 5 comprising a flowmeter sensor 10 and meter electronics 20.
- Meter electronics 20 is connected to meter sensor 10 via leads 100 to provide density, mass flow rate, volume flow rate, totalized mass flow, temperature, and other information over path 26.
- the present invention can be used by any type of Coriolis flowmeter 5 regardless of the number of drivers, the number of pick-off sensors, the operating mode of vibration.
- the present invention may be used in any system that vibrates the two flow tubes 103A-103B in order measure Coriolis effects as a material flows through the flow tube and then uses the Coriolis effect to measure a property of the material.
- Flowmeter sensor 10 includes a pair of flanges 101 and 101'; manifolds 102-
- Flanges 101-101' are affixed to manifolds 102-102'.
- Manifolds 102-102' are affixed to opposing ends of flow tubes 103A-103B.
- Brace bars 120-121 are affixed to the flow tubes 103A -103B as described below.
- Driver 104 is affixed to flow tubes 103A-103B in position where the driver can vibrate flow tubes 103A-103B in opposition to one another.
- Pick-offs 105-105' are affixed to flow tubes 103A-103B at opposing ends to detect the phase difference in the vibrations at opposing ends of flow tubes 103A-103B.
- Flanges 101 and 101" are affixed to manifolds 102-102' and connectflowtubes 103A and 103B to a pipeline (not shown).
- material enters flowmeter sensor 10 through inlet flange 101 and the total amount of material is divided into two flows by inlet manifold 102 and is directed equally to enter flow tubes 103A and 103B.
- the material then flows through flow tubes 103A and 103B back into outlet manifold 102' which joins the separate flows.
- the material then flows through outlet flange 101 ' where it exits meter sensor 10.
- Manifolds 102 and 102' are made of a minimal amount of material.
- Flow tubes 103A and 103B are selected and appropriately mounted to inlet manifold 102 and outlet manifold 102' so as to have substantially the same mass distribution, moments of inertia, and elastic modulus about bending axes W-W and
- the flow tubes extend outwardly from the manifolds in an essentially parallel fashion.
- Flow tubes 103A-B are driven by driver 104 in phase opposition about their respective bending axes W and W' and at what is termed the first out of phase bending mode of the flowmeter.
- Driver 104 may comprise one of many well known arrangements, such as a magnet mounted to flow tube 103A and an opposing coil mounted to flow tube 103B. An alternating current is passed through the opposing coil to cause both flow tubes 103A-B to oscillate.
- a suitable drive signal is applied by meter electronics 20, via lead 110 to driver 104.
- FIG. 1 is provided merely as an example of the operation of a Coriolis flowmeter and is not intended to limit the teaching of the present invention.
- Meter electronics 20 receives the right and left velocity signals appearing on leads 111 and 111 ', respectively.
- Meter electronics 20 also produces the drive signal on lead 110 which causes driver 104 to oscillate flow tubes 103A and 103B.
- the present invention as described herein, can produce multiple drive signals for multiple drivers.
- Meter electronics 20 process left and right velocity signals to compute mass flow rate.
- Path 26 provides an input and an output means that allows meter electronics 20 to interface with an operator.
- the internal components of meter electronics 20 are conventional. Therefore, a complete description of meter electronics 20 is omitted for brevity.
- Coriolis flowmeter sensor 10 allows flow tubes 103A-103B to have a smaller flag dimension while maintaining the accuracy of the readings within .5% of the actual mass flow rate.
- Flag dimension is the length that a loop in a flow tube protrudes outward from a plane that is perpendicular to the loop and that contains the connected pipeline.
- a second advantage of the configuration of Coriolis flowmeter sensor 10 is that a less expensive manifold and spacer may be used.
- flow tubes 103A-103B have a substantially semicircular arc 150-150' between an inlet end 151-151 ' and an outlet end 152-152'.
- Substantially semicircular arc 150-150' reduces the flag dimension since by creating a continuous curve in flow tubes 103A-103B.
- Substantially semicircular arc 150 must be used in order to allow flow tubes 103A-103B to be of a sufficient diameter to facilitate large flow rates of material flowing through Coriolis flowmeter 5.
- inlet manifold 102 and outlet manifold 102' may have a substantially 90 degree bend in a flow path to direct flow from the pipeline into substantially semicircular arc 150-150'.
- first brace bar 120 and a second brace bar 121 are affixed to flow tubes 103A and 103B.
- First brace bar 120 is affixed to flow tubes 103A-103B proximate inlet end 151 to connect flow tubes 103A and 103B to control oscillations of flow tubes 103A-103B.
- Second brace bar 121 is affixed to flow tubes 103A-103B proximate outlet end 152 to connect flow tubes 103A and 103B to control oscillations of flow tubes 103A-103B.
- first brace bar 120 and second brace bar 121 are affixed to flow tubes 103A-103B substantially 180 degrees apart from each other on substantially semicircular arc 150.
- Driver 104 is affixed to flow tube 103A and 103B at a position on semicircular arc 150 that is substantially at a midpoint between inlet 151 and outlet 152 of flow tubes 103A-103B. This position allows driver 104 to apply the greatest amount of force to flow tubes 103A-103B using the least amount of power.
- Driver 104 receives signals from meter electronics 20 via path 110 that cause driver 104 to oscillate at a desired amplitude and frequency.
- the frequency of a vibration is substantially equal to a first out of phase bending mode of flow tubes 103A-103B which is a higher frequency than conventional Coriolis flowmeters.
- a first out of phase bending mode of flow tubes 103A-103B which is a higher frequency than conventional Coriolis flowmeters.
- Pick-off sensors 105-105' In order to vibrate flow tubes 103A-103B at a high frequency and low amplitude.
- Pick-off sensors 105-105' must be affixed to flow tubes 103A-103B at position where the greatest amount of vibration may be sensed in flow tubes 103A- 103B. This allows pick-off sensors 105-105' to detect the greatest amount of effect of Coriolis forces caused by the flowing material.
- the pick- off sensors are positioned at a position that is substantially 30 degrees from axises w- w'.
- the pick-off sensors may be placed at a position anywhere between 25 and 50 degrees from the w-w' axises when conventional electronics are used to drive the flowmeter.
- FIG. 2 illustrates a spacer 200 affixed to flowmeter sensor 10.
- Space 200 maintains a constant distance between inlet manifold 102 and outlet manifold 102'.
- spacer 200 is made of minimal material.
- Spacer 200 has square ends 190-191 on opposing sides. In a preferred exemplary embodiment, the square ends 190-191 are cast as square plates in manifolds 102-102'.
- Four Walls represented by walls 201-202 connect each edge of square bases 190-191 to form an enclosure. Openings 210 allow substantially semicircular arcs 150-150' of flow tube 103A-103B to protrude from spacer 200.
- FIG. 3 illustrates a casing 300 for enclosing flow tube 103A-103B (Shown In FIG. 1 ).
- Casing 300 is a structure having a hollow inside that fits over flow tubes 103A-103B and is affixed to spacer 200 in some manner such as a weld, or nuts and bolts. Casing 300 prevents atmosphere from entering the enclosure.
- Casing 300 may resonate at a frequency that is substantially equal to the frequency of the desired mode of vibration of flowtubes 103A-103B. Ifthis is the case it is desirable to change the resonant frequency of casing 300 to prevent misreadings of the vibrations of flow tubes 103A-103B.
- One solution is to affix mass 301 to a substantially flat portion 302 of casing 300.
- the mass may be added as part of casing 300.
