DETAILED DESCRIPTION OF THE INVENTION

(6) FIGS. 2-5 and the following description depict specific examples to teach those skilled in the art how to make and use the best mode of embodiments of a vibrating meter. 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 present description. Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of the vibrating meter. As a result, the embodiments described below are not limited to the specific examples described below, but only by the claims and their equivalents.

(7) FIG. 2 shows a vibrating meter 5 according to an embodiment. The vibrating meter 5 comprises a sensor assembly 200 and a meter electronics 20. The sensor assembly 200 and the meter electronics 20 can be in electrical communication with one another via leads 10. The vibrating meter 5 is shown as comprising a Coriolis flow meter. However, those skilled in the art will readily recognize that the vibrating meter 5 may comprise other types of sensors that lack the measurement capabilities of Coriolis flow meters. For example, the vibrating meter 5 may comprise a vibrating densitometer, a vibrating volumetric flow meter, etc. Therefore, while the discussion that follows relates to a Coriolis flow meter, the embodiments should in no way be so limited.

(8) According to an embodiment, the sensor assembly 200 comprises a single fluid conduit 203, which forms two or more loops 204A, 204B to create a dual loop, serial flow path sensor assembly. Therefore, while two loops 204A, 204B are shown in the figures and described, the sensor assembly 200 may include more than two loops while remaining within the scope of the claims that follow. According to an embodiment, the fluid conduit 203 is mounted on a one-piece conduit mount 205. As can be appreciated, the fluid conduit 203 and the one-piece conduit mount 205 can be enclosed by a case (See FIG. 5) during use. The one-piece conduit mount 205 can be coupled to the fluid conduit 203 at more than one location. For example, the one piece conduit mount 205 can comprise an inlet port 206, which can be coupled to a fluid pipeline (not shown). An inlet conduit portion 207 of the fluid conduit 203 can be received by the inlet port 206. The one-piece conduit mount 205 can also comprise an outlet port 208, which can be coupled to the fluid pipeline and also receive an outlet conduit portion 209. According to an embodiment, the inlet and outlet conduit portions 207, 209 can be coupled to the inlet and outlet ports 206, 208 to form fluid-tight connections. Additionally, a portion of the inlet and outlet conduit portions 207, 209 can be coupled to a conduit support base 210 (See FIG. 4, for example) of the one-piece conduit mount 205. According to an embodiment, the conduit support base 210 can extend substantially completely between the inlet and outlet ports 206, 208. The conduit support base 210 can provide a suitable mounting surface for various portions of the fluid conduit 203.

(9) According to an embodiment, the fluid conduit 203 can extend from the inlet conduit portion 207 towards the first loop 204A. According to the embodiment shown, as the fluid conduit 203 extends upwards away from the conduit support base 210 to form the first loop 204A, the fluid conduit 203 can be coupled to a first support block 211. The first support block 211 can be coupled to the conduit support base 210 or may comprise an integral portion of the conduit support base 210, for example. The first support block 211 is shown extending from the conduit support base 210 upwards as shown in the figures.

(10) The fluid conduit 203 can extend away from the first support block 211 where it forms the first loop 204A. The first loop 204A can also be coupled to a second support block 212. The first and second support blocks 212 can help support the first and second loops 204A, 204B and aid in defining the loops' bending axes (See FIG. 5). The first and second support blocks 211, 212 can also help position the first and second loops' planes, P1, P2 (See FIG. 3). According to an embodiment, the fluid conduit 203 is coupled to the second support block 212 as the conduit 203 exits the first loop 204A and enters the crossover section 213. According to an embodiment, the crossover section 213 provides the transition between the first and second loops 204A, 204B.

(11) According to an embodiment, the crossover section 213 can be coupled to the one-piece conduit mount 205. More specifically, in the embodiment shown, the crossover section 213 can be coupled to the conduit support base 210. The crossover section 213 can be coupled to the conduit support base 210 using a variety of methods such as brazing, welding, mechanical fasteners, adhesives, etc. The particular method used for coupling the crossover section 213 to the conduit support base 210 is not important for purposes of the present application and should in no way limit the claims that follow. According to an embodiment, the crossover section 213 may be coupled to the conduit support base 210 in multiple locations. As can be appreciated, unlike the anchor 106 of the prior art vibrating meter 100, which allows the crossover section 105 to hang freely, the one-piece conduit mount 205 is coupled to the crossover section 213 to ensure that the crossover section 213 is properly supported. As shown, the crossover section 213 is coupled to a top surface (during normal orientation) of the one-piece conduit mount 205 such that the weight of the crossover section 213 can be supported by the conduit support base 210. Therefore, vibrations and stresses that are experienced by the crossover section 213 can be minimized. Furthermore, because the conduit support 213 is formed of one piece, stresses that may be experienced as the case 500 is installed or when the sensor assembly 200 is installed in the pipeline can be absorbed by the conduit mount 205 rather than the fluid conduit 203.

(12) As the fluid conduit 203 extends from the crossover section 213 towards the second loop 204B, the fluid conduit 203 can be coupled to the first support block 211 once again. However, as the fluid conduit 203 enters the second loop 204B, the fluid conduit 203 is coupled to the opposite side of the first support block 211. The fluid conduit 203 creates the second loop 204B and extends towards the outlet conduit portion 209. According to an embodiment, the fluid conduit 203 can also be coupled to the second support block 212 as the fluid conduit 203 transitions from the second loop 204B to the outlet conduit portion 209.

(13) With the fluid conduit 203 securely coupled to the one-piece conduit mount 205, a driver 225 can vibrate the first and second loops 204A, 204B in phase opposition about bending axes W-W, W-W (See FIG. 5), which are at least partially defined by brace bars 220-223. The driver 225 can receive a drive signal via lead 235 from the meter electronics 20. As the first and second loops 204A, 204B vibrate, the motion can be detected by first and second pick-off sensors 226, 226. The pick-off signals can be transmitted to the meter electronics 20 via leads 236, 236 to determine one or more fluid characteristics of the fluid within the fluid conduit 203, such as a mass flow rate, a volume flow rate, a density, a temperature, etc.

(14) FIG. 3 shows a top view of the fluid conduit 203 according to an embodiment. In FIG. 3, the fluid conduit 203 is shown prior to being coupled to the one-piece conduit mount 205. As can be seen, the fluid conduit 203 includes the inlet conduit portion 207, which transitions into the first loop 204A. Near the end of the first loop 204A, the fluid conduit 203 transitions into the crossover section 213. According to an embodiment, the crossover section 213 can join the first and second loops 204A, 204B. The crossover section 213 traverses from the first plane P1 to the second plane P2. The second loop 204B then ends at the outlet conduit portion 209. According to an embodiment, the first and second loops 204A, 204B are in substantially parallel planes P1, P2, respectively. As discussed above, in some embodiments, the first and second support blocks 211, 212 can help define the planes P1, P2. By providing the two loops in parallel planes, the two loops 204A, 204B can be vibrated with respect to one another and can act as a dual loop, parallel flow path flow meter even though the two loops 204A, 204B comprise a serial flow path.

(15) FIG. 4 shows a portion of the sensor assembly 200 according to an embodiment. In FIG. 4, a better view of the inlet portion 207, which is coupled to the conduit support base 210 is shown. The conduit support base 210 includes two apertures 440. The apertures 440 can be provided to receive a fixture (not shown) used in coupling the fluid conduit 203 to the one-piece conduit mount 205.

(16) FIG. 5 shows another view of the sensor assembly 200 according to an embodiment. In FIG. 5, a portion of the case 500 is now provided. As can be appreciated, another corresponding case portion can be coupled to the portion shown to fully enclose the fluid conduit 203.

(17) In FIG. 5, the conduit support base 210 is shown in better detail. As can be seen in FIG. 5, the crossover section 213 extends between the first and second support blocks 211, 212. A plurality of apertures 440 are shown in the one-piece conduit mount 205, which are provided to accommodate coupling fixtures used in coupling the fluid conduit 203 to the conduit mount 205.

(18) In the embodiment shown, the support blocks 211, 212 can be tapered to accommodate the crossover's change from the first plane, P1 to the second plane, P2. For example, the second support block 212 is shown comprising a first width, t.sub.1 at the end closest to the outlet port 208 and a second width, t.sub.2 at the end closest to the first support block 211. In the embodiment shown, t.sub.2 is less than t.sub.1. According to an embodiment, the first support block 211 can also be tapered. In the embodiment shown, the support blocks 211, 212 can also help the brace bars 220, 221 define the bending axes W-W, W-W. As can be seen, the embodiment shown in FIG. 5 only includes a single brace bar 220, 221 on each end. Therefore, the support blocks 211, 212 can act as a second brace bar in some embodiments.

(19) Also shown in FIG. 5 in more detail are the driver and pick-off components. According to an embodiment, the driver 225 comprises a first driver component 225A coupled to the first loop 204A and a second driver component 225B coupled to the second loop 204B. Likewise, the first and second pick-off sensors 226, 226 comprise a first pick-off sensor component 226A, 226A coupled to the first loop 204A and a second pick-off sensor component 226B, 226B coupled to the second loop 204B, respectively. As discussed above, the driver 225 and pick-off 226, 226 components may comprise a magnet/coil combination, which is generally known in the art or some other type of configuration that allows for vibration and the detection of motion of the loops 204A, 204B.

(20) The embodiments described above provide an improved multiple loop, serial flow path vibrating meter. Unlike prior art meters that separate the fluid tube's support into multiple components, the embodiments described above comprise a one-piece conduit mount 205. The one-piece conduit mount 205 can provide better support for the fluid conduit's crossover section 213 than in the prior art. The additional support for the crossover section 213 can minimize distortions and external vibrations experienced by the pick-offs 226, 226.

(21) The detailed descriptions of the above embodiments are not exhaustive descriptions of all embodiments contemplated by the inventors to be within the scope of the present description. Indeed, persons skilled in the art will recognize that certain elements of the above-described embodiments may variously be combined or eliminated to create further embodiments, and such further embodiments fall within the scope and teachings of the present description. It will also be apparent to those of ordinary skill in the art that the above-described embodiments may be combined in whole or in part to create additional embodiments within the scope and teachings of the present description.

(22) Thus, although specific embodiments are described herein for illustrative purposes, various equivalent modifications are possible within the scope of the present description, as those skilled in the relevant art will recognize. The teachings provided herein can be applied to other vibrating meters, and not just to the embodiments described above and shown in the accompanying figures.
