6 PFS-WM THE PFS WEDGETYPE FLOW METER PRODUCT BULLETIN DOCUMENT NUMBER: REV00 A Flow Metering Solution for harsh service, highly viscous, slurry type, or contaminated primary line fluid applications (but ideal for conventional liquid, gas and steam applications as well!) Introduction In the public domain for over fifty years, the Wedge meter has served in numerous applications, however due to the unique nature of the Wedge meter design, it has been found to be particularly useful in applications characteristically involving harsh, contaminated, high viscosity, air or particulate entrained line fluids such as sewage, steam, tar sands, molasses, cement, and petroleum products. Primary Flow Signal, Inc. offers the PFS Wedgetype flow meter in a selection of configurations, line sizes, pressure ratings and material selection to bracket a broad cross section of installation and application requirements. In all instances, Primary Flow Signal, Inc. brings decades of design, engineering, manufacturing and innovation expertise, experience and leadership to this important and useful line of flow measurement devices. A broad range of sizes and configurations of the PFS Wedgetype flow metering element is likely to accommodate nearly any installation requirement. Rely on the expert assistance available from the applications specialists at Primary Flow Signal, Inc. to tailor make special configurations in cases where standard design protocols may be insufficient. This product is characterized by stable coefficient performance, good to excellent accuracy, moderate headloss(less than orifice), good repeatability, high viscosity tolerance, unaffected by sedimentary secondary phase, low cost, long service life, and no maintenance requirements. The operating principal of the PFS Wedgetype flow meter is analogous to that of other differential producing flow meters such as orifice plates or Venturi meters in the respect that the pressure difference measured across a flow constriction in this case a sloping wedge is related to the velocity of the flow passing through the narrowest cross section of the flow element. Pressure taps are located upstream and downstream from a vee shaped constriction placed in a length of pipe. The constriction creates a pressure drop between the upstream tap and downstream tap which is related to the velocity in the pipe line, and thus, inferentially, to the volumetric flow rate through the narrowest cross section of the flow element thereby created. FLOW P General Information The opening height of the wedge can be changed in design according to the amount of differential required for a particular application flow range modified by the tolerance for permanent pressure loss.

PAGE 2 Materials of construction may be selected from any commercially available flange material with surface finishes to coordinate with service requirements. The tap arrangement is designed to penetrate the flange and reach the inside diameter of the flow element. Internal NPT threading is typical, but again, subject to the constraints imposed by bolt pattern, virtually any tap threading, or welded couplings can be incorporated as required.

17 PFS-WM THE PFS WEDGETYPE FLOW METER PRODUCT BULLETIN Installation Information The proper operation of the PFS Wedgetype flow element installations. The element should be rotated between 45 to is relatively forgiving of the specific installation arrangement imposed. Nevertheless, to achieve the best results, the recommended installation parameters enumerated below should be observed and incorporated. The adverse results arising from failure to properly install the flow element can include plugging of impulse lines and/or tap holes, air (gas or unwanted secondary phase) entrapment in the taps and/or impulse lines, introduction of a minor hydrostatic head effect (in a vertically orientated installation) or Kd2 shift (i. e. accuracy impairment. Meter Orientation A horizontal orientation is preferred and typical for most 90 degrees resulting in the tap locations that substantially allow any undissolved solids to easily pass beneath the wedge without build-up and also minimizes air (or gas) entrapment at the tap locations. (See figure 9.) Vertical installations may result in a hydrostatic head effect due to the elevation difference of the individual impulse lines. This can (and must) be corrected by adjusting (calibrating) the transmitter. Other orientations and installations are permissible, providing adequate consideration and accommodation is made by virtue of proper venting and compensation for relative differences in impulse/tap elevations. Figure 9: Recommended Installation Orientation Straight Pipe Requirement The PFS Wedgetype flow element will produce the performance envelope profiled elsewhere hereunder subject to the nature of the process piping and disturbers located therein. As with most flow meters, straight (unrestricted) piping upstream and downstream of the flow element is preferred and will produce better results and accuracy. Providing adequate straight piping upstream and downstream, however, can significantly normalize the performance accuracy, despite the presence of disturbers. General guidance is offered in Table 9 below with all dimensions provided being considered from the apex of the wedge element. Table 9: Typical Straight Pipe Length Requirements.
