Detailed Description
Fig. 1-8 and the following description depict specific examples to teach those skilled in the art how to make and use the best mode of implementation of a shroud for meter electronics in an interface. For the purpose of teaching inventive principles, some conventional aspects have been simplified or omitted. Those skilled in the art will appreciate variations from these examples that fall within the scope of the description. Those skilled in the art will appreciate that the features described below may be combined in various ways to form multiple variations of using a shroud for meter electronics in an interface. Therefore, the embodiments described below are not limited to the specific examples described below, but only by the claims and their equivalents.
Fig. 1 shows a vibrating meter 5 with an interface 2, the interface 2 having improved accessibility. As shown in fig. 1, the vibrating meter 5 includes a sensor assembly 10, the sensor assembly 10 being mechanically and communicatively coupled to the interface 2 via a feedthrough 15. The sensor assembly 10 may be inserted into a pipe at the flanges 10a, 10b to receive and measure material and return the material to the pipe.
The interface 2 may include meter electronics including two or more electronics boards arranged in a multi-planar configuration. That is, each of the two or more electronics boards may each be a board that lies in a plane. The planes of two or more electronics boards may be parallel to each other and not intersecting. Thus, two or more electronics boards may be parallel and spaced apart from each other. As will be described in greater detail below, two or more electronics boards may be disposed within and mechanically coupled to a shroud that may mechanically fix the two or more electronics boards in place relative to each other and the housing. The shroud may also provide a ground path for two or more electronics boards. These and other features will be discussed below.
Fig. 2 shows a vibrating meter 5 comprising an interface 2 with improved accessibility, wherein the housing for the interface 2 and the sensor assembly 10 is not shown for the sake of clarity. As shown in fig. 1, the vibrating meter 5 includes a sensor assembly 10 and meter electronics 20, wherein the meter electronics 20 are disposed in the interface 2 shown in fig. 1. The sensor assembly 10 is responsive to the mass flow rate and density of the process material. Meter electronics 20 is connected to sensor assembly 10 via leads 100 to provide density, mass flow rate, and temperature information, among other information, in port 26.
The sensor assembly 10 includes a pair of manifolds 150 and 150 ', flanges 103 and 103' having flange necks 110 and 110 ', a pair of parallel conduits 130 and 130', an actuator 180, a Resistance Temperature Detector (RTD)190, and a pair of inductive sensors 170l and 170 r. The conduits 130 and 130 'have two substantially straight inlet legs 131, 131' and outlet legs 134, 134 ', the inlet legs 131, 131' and outlet legs 134, 134 'converging towards each other at the conduit mounting blocks 120 and 120'. The conduits 130, 130 ' are curved at two symmetrical locations along the length of the conduits 130, 130 ' and are substantially parallel throughout the length of the conduits 130, 130 '. Struts 140 and 140 ' serve to define axes W and W ' about which each conduit 130, 130 ' oscillates. The legs 131, 131 ' and 134, 134 ' of the conduits 130, 130 ' are fixedly attached to the conduit mounting blocks 120 and 120 ', and these blocks are in turn fixedly attached to the manifolds 150 and 150 '. This provides a continuous closed material path through the sensor assembly 10.
When flanges 103 and 103 ' with holes 102 and 102 ' are connected to a process line (not shown) carrying the process material being measured via inlet end 104 and outlet end 104 ', the material enters the inlet end 104 of the metering device through an aperture 101 in flange 103 and is directed through manifold 150 to conduit mounting block 120 with surface 121. Within the manifold 150, the material is separated and conveyed through the conduits 130, 130'. Upon exiting the conduits 130 and 130 ', the process material is recombined in a single stream within the block 120 ' having the surface 121 ' and the manifold 150 ', and then carried to the outlet end 104 ' connected to the process line (not shown) by the flange 103 ' having the holes 102 '.
The conduits 130, 130 'are selected and the conduits 130, 130' are suitably mounted to the conduit mounting blocks 120, 120 'so as to have substantially the same mass distribution, moment of inertia, and young's modulus about the bending axes W-W and W '-W', respectively. These bending axes pass through the struts 140, 140'. Since the young's modulus of the conduit changes with temperature, and this change affects the calculation of flow and density, the RTD 190 is mounted to the conduit 130 ' to continuously measure the temperature of the conduit 130 '. The temperature of the conduit 130 'and thus the voltage across the RTD 190 that occurs for a given current through the RTD 190 is determined by the temperature of the material through the conduit 130'. The meter electronics 20 uses the temperature-dependent voltage that appears across the RTD 190 in a known manner to compensate for changes in the modulus of elasticity of the conduits 130, 130' due to any changes in the temperature of the conduits. The RTD 190 is connected to the meter electronics 20 by leads that carry an RTD signal 195.
Two of the conduits 130, 130 ' are driven by the driver 180 in opposite directions about the respective bending axes W and W ' of the conduits 130, 130 ' and in a so-called first out of phase bending mode of the flow meter. The driver 180 may comprise any one of a number of well-known devices, such as a magnet mounted to the catheter 130 'and an opposing coil mounted to the catheter 130, and through which an alternating current is passed for vibrating both catheters 130, 130'. An appropriate drive signal 185 is applied by meter electronics 20 to driver 180 via leads.
Mass flow rate measurement
Can be generated according to the following equation:
the Δ t term includes an operationally derived (i.e., measured) time delay value that includes a time delay that exists between the detection of the sensor signal, such as due to the Coriolis effect associated with the mass flow rate through the vibrating meter 5. The measured Δ t term ultimately determines the mass flow rate of the flowing material as it flows through the vibrating meter 5.Δ t0The term includes the time delay at zero flow calibration constant. Δ t0Items are typically determined at the factory and programmed to vibrateIn meter 5. Time delay at zero flow Δ t even with varying flow conditions0The items may not change. The mass flow rate of the flow material flowing through the flow meter is determined by multiplying the measured time delay by a flow calibration factor FCF. The flow calibration factor FCF is proportional to the physical stiffness of the flow meter.
With respect to density, the resonant frequency at which each conduit 130, 130 ' will vibrate may be a function of the square root of the spring constant of the conduit 130, 130 ' divided by the total mass of the conduit 130, 130 ' with material. The total mass of the conduit 130, 130 ' with material may be the mass of the conduit 130, 130 ' plus the mass of the material inside the conduit 130, 130 '. The mass of material in the conduits 130, 130' is proportional to the density of the material. Thus, the density of the material may be proportional to the square of the period of oscillation of the conduit 130, 130 'containing the material multiplied by the spring constant of the conduit 130, 130'. Thus, by determining the period of oscillation of the conduit 130, 130 'and by appropriately scaling the results, an accurate measurement of the density of the material contained by the conduit 130, 130' may be achieved. The meter electronics 20 can utilize the sensor signal 165 and/or the drive signal 185 to determine the period or resonant frequency. The meter electronics 20 may include an electronics board housed and encompassed by a shroud, as described in more detail below.
Fig. 3 shows an interface 2 comprising meter electronics 20, the meter electronics 20 having a shroud 200. As shown in fig. 3, the shroud 200 is part of the meter electronics 20. The meter electronics 20 is an assembly that includes a shroud 200 and one or more electronics boards. The one or more electronics boards are not shown, but are discussed below with reference to fig. 5-7. Referring to fig. 3, the shroud 200 is mechanically coupled to the housing 300 at one or more mounting points, which, as will be discussed in more detail below, define a shroud-housing mounting plane.
As shown in fig. 3, the shroud 200 is configured to cover, extend around, and/or be received at one or more electronics boards. The housing 300 may be configured to mate with a housing. For example, as will be described in more detail below, the shroud 200 is configured to mechanically couple to the housing 300 at three or more shroud-housing mounting points within a shroud-housing mounting plane that includes or is proximate to a center of mass of the meter electronics 20. Because the shroud-housing mounting plane includes or is adjacent to the centroid of the meter electronics 20, the moment at the shroud-housing mounting point can be less than the moment threshold so as not to fail due to periodic forces, e.g., caused by vibrations and the like.
Fig. 4 shows a shroud 200 for the meter electronics 20 described above. As shown in fig. 4, the shroud 200 includes three shroud-housing mounting points 202, although more shroud-housing mounting points may be employed in alternative shrouds. The three shroud-housing mounting points 202 define a shroud-housing mounting plane 202 p. As will be explained in more detail below with reference to fig. 6 and 7, shroud-housing mounting plane 202p includes or is adjacent to the centroid of meter electronics 20. Also shown in fig. 4 are four second plate mounting points 208, the four second plate mounting points 208 defining a second shroud-plate mounting plane 208 p. Three or more than four board mounting points may be employed in alternative shrouds. As shown in fig. 4, the second shroud-plate mounting plane 208p is non-planar with the shroud-housing mounting plane 202p and parallel to the shroud-housing mounting plane 202p, although any suitable spatial relationship may be employed.
The shroud 200 may be configured to house one or more electronics boards. For example, a first electronics board may be mounted to three shroud-housing mounting points 202, and a second electronics board may be mounted to four second board mounting points 208. For clarity, the first electronics board and the second electronics board are not shown. Thus, the first electronics board may be parallel to the second electronics board, although any suitable spatial relationship of the electronics boards may be employed.
Also shown in FIG. 4 is wall 204, which wall 204 may be configured to receive an electronics board. For example, the wall 204 may enclose a first electronics board mounted to three shroud-housing mounting points 202 and a second electronics board mounted to four second board mounting points 208. The wall 204 and electronics board may provide structural rigidity that may prevent displacement of the electronics boards relative to each other and/or the housing 300, for example. As can be observed, the wall 204 has a cylindrical shape, although any suitable shape may be employed. Accordingly, the first and second electronics boards may have a circular shape.
The shroud 200 also includes a face 206, the face 206 being shown parallel to the shroud-housing mounting plane 202p and the second shroud-plate mounting plane 208p, although any suitable spatial relationship may be employed. More specifically, face 206 includes a substantially flat portion that is parallel to shroud-housing mounting plane 202p and second shroud-plate mounting plane 208 p. The face 206 is connected to the wall 204 of the shroud 200. More specifically, face 206 is integrally formed with wall 204.
As can be seen in fig. 4, the shroud-housing mounting point 202 and the second plate mounting point 208 are also integral with the shroud 200. More specifically, the shroud-housing mounting point 202 and the second plate mounting point 208 are integral with the wall 204 of the shroud 200. The shroud 200 shown in fig. 4 may be formed as a single unitary piece by injection molding, 3D printing, or the like, although any suitable manufacturing process and/or structure may be employed. Such a manufacturing process and/or design may be less expensive than, for example, the manufacturing process and/or design associated with the use of standoffs. The housing 300 may house, encompass, and support electronics boards that can improve the mechanical reliability of the meter electronics, as described in more detail below.
Fig. 5 shows the meter electronics 20 including the shroud 200, the shroud 200 housing an electronics board 400. As shown in fig. 5, the electronics board 400 is exploded from the cover shield 200. More specifically, the first electronic device board 400a may be mounted to the shroud-housing mounting point 202 shown in fig. 4, and the second electronic device board 400b may be mounted to the second board mounting point 208 shown in fig. 4. However, as shown in fig. 5, the electronics board 400 is exploded from the shroud-housing mounting point 202 and the second board mounting point 208. As can be understood with reference to fig. 4 and 5, the first and second electronics boards 400a and 400b are parallel to each other and to the face 206.
Fig. 6 and 7 show cross-sectional views of the shroud 200 mounted to the housing 300 at the shroud-housing mounting plane 202 p. As shown in fig. 6 and 7, the cover 200 accommodates the electronics board 400 including a first electronics board 400a and a second electronics board 400 b. The first electronics board 400a is shown forming a first electronics board plane 400 ap. The first electronics board plane 400ap is adjacent to the shroud-housing mounting plane 202 p. The bolts at the shroud-housing mounting point 202 extend through the shroud 200 and the first electronics board 400a into the housing 300. Thus, the first electronics board 400a may be grounded to the housing 300, wherein the housing 300 is configured to mate with the shroud-housing mounting point 202.
The centroid CM for the meter electronics 20 is also shown. The center of mass CM shown is the center of mass of the shroud 200 and the electronics board 400 and components attached to the electronics board 400. Thus, the mass of the meter electronics 20 extends to the wall 204 of the shroud 200. The center of mass CM for the meter electronics 20 is shown adjacent to the first electronics board plane 400ap and the second board mounting plane 208 p. Because the centroid CM is adjacent to the second board mounting plane 208p, any acceleration of the meter electronics 20 directly parallel to the second board mounting plane 208p does not cause a significant moment at the shroud-housing mounting point 202. Thus, the meter electronics 20 may not be rotationally displaced relative to the shroud-housing mounting point 202.
Shroud-housing mounting points 202 are shown disposed outside of walls 204 and proximate to an outer region of the mass of meter electronics 20. The outer region of the mass of the meter electronics 20 includes the wall 204 of the shroud 200. In an alternative meter electronics, the shroud-housing mounting point may be disposed at an outer region of a mass of the meter electronics. Because the shroud-housing mounting point 202 is disposed outside of the wall 204 and/or near an opposite portion of the outer region of the mass of the meter electronics 20 (where the shroud-housing mounting plane 202p is also adjacent to or includes the centroid CM of the meter electronics), the location of the shroud-housing mounting point 202 can have a maximum or relatively large moment arm from the centroid CM of the meter electronics, and thus can minimize the force applied at the shroud-housing mounting point 202.
FIG. 8 illustrates a method 800 for forming meter electronics including a shroud. As shown in fig. 8, the method 800 begins with providing one or more electronics boards in step 810. The one or more electronics boards may be the same as the electronics board 400 discussed above, although any suitable electronics board may be employed. In step 820, the method 800 provides a shroud. The shield may be the shield 200 discussed above, although any suitable shield may be employed. The shroud may include three or more shroud-housing mounting points configured to mount to the housing. The three or more shroud-housing mounting points may define a shroud-housing mounting plane that includes or is adjacent to a centroid of the meter electronics.
In step 820, forming the shroud may further include forming a wall configured to house at least one electronics board in the meter electronics. Three or more shroud-housing mounting points may be integral with the wall. The method 800 may also configure the three or more shroud-housing mounting points to compress a first electronics board of the one or more electronics boards into the housing in order to ground the first electronics board to the housing. The method 800 may also configure the shroud to include three or more second plate mounting points to define a second plate mounting plane, wherein the shroud-housing mounting plane and the second plate mounting plane are substantially parallel. The shroud-housing mounting plane may include or be adjacent to a board plane defined by the first electronics board. The step 820 of forming the housing may also include forming a face of the shroud that is parallel to the shroud-housing mounting plane.
The shroud 200 and method 800 described above can improve the mechanical and/or electrical reliability of the meter electronics 20 by reducing the moment about the center of mass CM of the meter electronics 20. For example, the shroud-housing mounting plane 202p may be adjacent to or include the centroid CM of the meter electronics 20. Thus, any vibration, force, etc. applied to the meter electronics parallel to the plane may not cause a moment about the shroud-housing mounting point 202 or the centroid CM of the meter electronics 20. Additionally, shroud-housing mounting points 202 at or near opposing portions of the outer region of the mass of meter electronics 20 may reduce any forces applied to shroud-housing mounting points 202. Further, the shroud 200 encompassing the electronics board 400 may allow the shroud-housing mounting points 202 to be located at or near opposing portions of the outer region of the mass of the meter electronics 20. Finally, the shield 200 may have a simpler manufacturing process and/or design than, for example, standoffs, thereby reducing the cost of the interface 2.
