It is standby, allow one or more electronic equipments 20 to interact with operator.Circuit explanation without one or more electronic equipments 20
Understand the present invention, and is omitted so that this specification is brief.One feasible vibration is provided only as to the description of Fig. 1
The operational instances of dynamic flow device, and it is not intended to limit the teachings of the present invention.
Fig. 2 and Fig. 3 illustrates the shell 200 of embodiment according to the present invention.According to the one aspect of the present embodiment, shell
200 surround pipeline 103A, 103B, driver 104 and pick-up 105,105'.It will be appreciated by those skilled in the art that
The wall 210 of shell can limit one or more opening (not shown), for example, such as via the conducting wire that can be RTD electric wire
100,110,111,111' (such as drives at least one pick-up (such as pick-up 105-105') and at least one driver
Dynamic device 104) it is connected on one or more electronic equipments 20.
As shown, shell 200 is equipped with first end 201 and second end 202.In the exemplary embodiment, first end 201
It is fixed on plate 303, plate 303 is fixed on manifold 102 on the inlet side of vibrating flowing device 5, and second end 202
It is fixed on plate 304, which is fixed on manifold 102'.It will be recognized by those skilled in the art although describe
For one of shell 200 it is feasible be specifically designed, but can be using various methods come closed conduct 103A, 103B.For example, this
Field technical staff will recognize that, different with plate 303,304 or except its it for that will be fixed on vibrating flowing device
Shell 200 on outer position is within the scope of the invention.In addition, although plate 303 and plate 304 are in the shown embodiment
It is integrally set on manifold 102 and 102', but plate 303,304 can also be fixed to by manifold by welding or other methods
On 102 and 102'.Although shell is set as other constructions (for example, all in addition, shell 200 is shown with generally U-shaped
Such as straight line or irregular construction) be within the scope of the invention.
Turning now to Fig. 4, the shell (such as shell 200) of vibrating flowing device (such as vibrating flowing device 5) has more
A vibration mode, it may for example comprise but be not limited to about the vibration lateral mode of axis A and about the vibration bending die of axis B
Formula.In shown exemplary embodiment, axis B is roughly parallel to axis X and X' of the pipeline 103A and 103B about its oscillation
(being shown in Fig. 1), and axis A is generally normal to axis X, X' and B.
Each vibration mode of shell 200 is generated by a certain range of frequency.Cause the specific frequency of any specific mode
Rate is influenced by factors, for example, such as fluid density, environmental factor such as temperature, or the insulation that can be located at around shell 200
Twister.Fig. 5 shows in aforementioned shell, and specific hull vibration mode causes pipeline being substantially equal under certain condition
The frequency of the driving frequency of drive mode in 103A, 103B occurs.If Fig. 5 is also shown, shell is typically provided with one or more
A other modes occur in the frequency bigger than causing the driving frequency of drive mode.The frequency of vibration mode in causing shell
In the case that rate is substantially equal to the driving frequency for causing drive mode, it is difficult to generate the accurate survey to the characteristic of stream material
Amount.
According to an aspect of the present invention, the shell 200 of the present embodiment, which is constructed such that, vibrates mould in causing shell 200
The frequency of formula and cause in pipeline 103A, 103B drive vibration mode driving frequency between there are frequency separations.According to this reality
Apply the another aspect of example, shell 200 be constructed such that cause in shell 200 frequency of vibration mode and cause pipeline 103A,
It drives the driving frequency of vibration mode not identical under the conditions of corresponding operating in 103B and does not intersect.Again according to the present embodiment
On the other hand, shell 200, which is constructed such that, causes the frequency of vibration mode in shell 200 to be more than to cause in pipeline 103A, 103B
Drive the driving frequency of vibration mode.
Turning now to Fig. 6, typical shell (such as shell 300) has the cross sectional shape of general toroidal；Also, in driving mould
Formula be beam mode situation in, shell beam mode the direction of motion (i.e. generally normal to the side of such as axis of axis B
To) on have relatively low the moment of inertia.
However, in this type of design, as shown in Figure 5, cause buckling of shells mode frequency can under given conditions with
The driving frequency for being bent drive mode is caused to be intersected.
The frequency for generating vibration mode in the housing is related to the moment of inertia of shell.More specifically, following equation can be based on
Or the modification of following equation models vibration mode in its frequency occurred.
Wherein:
fi=generate the intrinsic frequency of the mode
The moment of inertia of I=on the mode direction
E=elasticity modulus
ρ=density of material
A=section of beam product
I=mode quantity
λi=characteristic value
Although the equation of front models the intrinsic frequency for suspended wall crossbeam, it for display the moment of inertia with
The relationship generated between the intrinsic frequency for vibrating specific mode is useful.More specifically, previous equations are instructed: with the moment of inertia
Increase, the frequency of any specific vibration mode is caused to increase.Therefore, according to an aspect of the present invention, it can use the principle
So that the vibration mode of shell 200 is being more than the frequency appearance of one or more of driving frequencies.For example, and not being limited
System, in the present embodiment, wherein beam mode be drive mode and buckling of shells mode frequency under given conditions with driving
Frequency translation, shell 200 can be provided having generally elliptical cross sectional shape.More specifically, as shown in Figure 4, curved
In the case that bent mode is drive mode, shell 200 can be provided having generally elliptical cross sectional shape, and be equipped with width
It spends W and size is greater than the length L of width W, wherein length L extends in the direction of motion of beam mode, and width W is substantially
It is orthogonal to the direction of beam mode.By following this method, the moment of inertia of shell 200 is increased, and as shown in Figure 7,
The frequency for causing vibration mode in shell is more than to cause the frequency of drive mode.
Although the bending shell mode of vibration tends to generation problem in precedent, specific mode or tends to and drive
The vibration mode that mode is intersected will depend on many factors, for example, the shape of such as pipeline, the shape of shell, specifically driving mould
Formula, fluid density and temperature.Therefore, it can be used to avoid the specific shell construction of frequency translation will within the scope of the invention
It is changed.Although utilizing its for preventing frequency translation for example, the present embodiment is shown equipped with elliptical shell 200
Its setting is within the scope of the invention.As example, the thickness or cross sectional shape that can choose wall 210 make in shell
The frequency that any specific mode is generated in 200 is more than that the frequency of drive mode is generated under the conditions of corresponding operating.As yet another
A example is especially drive mode in torsional mode and causes the frequency with driving frequency of torsional mode in shell that can tend to hand over
In the case where fork, as shown in Figure 8, such as strengthening part 400 can be fixed on shell 300 by welding.Strengthening part
400 can be equipped with any shape for reinforcing shell 300, it may for example comprise but it is not limited to oval ring shown in fig. 8.
It is of the invention best to instruct those skilled in the art how to manufacture and use that present specification describes specific examples
Mode.In order to instruct inventive principle, some conventional aspects have been simplified or omitted.It will be understood to those of skill in the art that coming from
The modification of these examples is fallen within the scope of the present invention.
