It is onecomponent of a flow measurement system. The Senior Orifice Fitting (Senior) is designedto: Position an orifice plate, concentric to flow moving through a pipeline, within API-14.3, Part 2 or ISO 5167 installation requirements. Allow personnel to remove and replace an orifice plate without disturbing the flowmeasurement system piping, with little, or no, interruption in service and withoutremoving the Senior from the system.The orifice plate within a Senior restricts the fluid moving through a pipe. This restrictioncreates a change in static pipe pressure of the fluid. Instrumentation measure thedifference in change of the fluid entering orifice plate bore, and once again after it exitsthe plate bore. This instrumentation then combines that information, along with otherdata gathered from the flowing fluid, and calculates the amount of fluid that passesthrough the system.The first chamber, or Body (4), properly positions the orifice plate in the flow stream. Thesecond chamber, or Top (14), is a temporary holding place for the orifice plate duringremoving or installing operations (Refer to Orifice plate installation and removalinstructions).8Senior Orifice Fitting

Owner and operator manualP/N 3-9008-001IntroductionMarch 2021ImportantThe unit components have part numbers assigned on appropriate drawings and tables.Refer to Figure 1-2 thru Figure 1-5 and Table 1-4 thru Table 1-8 for part numbers. Example:Body (4).Figure 1-1: Daniel Senior Orifice Fitting - Flangnek optionTherefore, using a Senior may eliminate the need for bypass piping, valves, and otherfittings necessary with conventional orifice fitting installations. Maintenance technicianscan replace and repair all parts of the Senior, including the slide valve assembly, withoutremoving the Body (4) from the line (refer to Maintain).Emerson designs and manufactures all Senior units to applicable API-14.3recommendations and in accordance with selected ANSI, ASME and ASTM specifications.As an option, Emerson also designs and manufactures fittings in compliance with ISO5167.Products bearing the "CE" mark are designed and manufactured in compliance with theEuropean Union Pressure Equipment Directive (PED) 2014/68/EU (available on theinternet).Refer to the "Daniel Orifice Fittings Installation and Operating Instructions specific to thePressure Equipment Directive", Part Number 3-9008-002 (available on the Emersonwebsite).Owner and operator manual9
