ROC V-Cone Tab

V-Cone Tab

The V-Cone tab is only used if a configuration has a V-Cone meter associated with one or more orifice meters. In ROCLink, under User Programs V-Cone configuration the V-Cone points are listed.

The V-Cone points can be configured to use Point Type 61 or 71. Find which it is using by examining one V-Cone point in ROCLink and look for references to Point Types of 61 or 71 (see below).

The number of V-Cone meters should be set to the number of V-Cone points configured in ROCLink. In this example: 12 (see above 2 images).

The AUTOSOL ROC driver will examine each of the V-Cone points looking for an associated Orifice Run. If it finds an associated orifice run, the logical that it finds in the TLP is the index of the meter associated with the V-Cone point. In the example configuration in the figure below, the first orifice meter is associated with the first V-Cone point. As a result, when this meter is published, flow coefficient will be read from this point (61.2:0 in this example), in the published output the meter type will be set to V-Cone and the Calculation Method will be set to V-Cone.
