2FPD175 COMPACT ORIFICE CARRIER ASSEMB LY DS/FPD175- EN—Orifice flow metering made simple—Optional integral temperature element Integral RTD facilitates mass (liquids and steam) andcorrected volume (gas) flowrate measurement—Integral manifold For direct mounting of DP or multivariable transmitter Optional fittings for impulse piping to facilitate remotemounting of transmitter—Reduced pipeline installation costs Eliminates need to supply and connect separate manifold,and impulse piping Multi-hole orifice plate improves accuracy and dramaticallyreduces straight pipe requirements—Flexible and accurate installation Wafer body fits flanges up to ASME 600 or DIN PN100 Optional tool for accurate centralization between flanges Optional replaceable orifice plates offer easy, economicmaintenance and flexibility

F PD 175 COMPACT OR I FI CE CARRIE R ASSE MBLY DS/FPD175-E N3—Balanced orifice conditioning plateThe FPD175 is an orifice-based primary element, designed forsimplified installation and commissioning.Utilizing NASA-designed Balanced Orifice technology, theconditioning plate variant of FPD175 offers significantadvantages over the conventional single-hole design.BenefitsThe FPD175 system avoids many of the difficulties involved inthe sizing, selection, procurement, installation andcommissioning of conventional orifice plate installations. Eliminates many of the problems of sourcing multiplecomponents. Provides savings in cost and time due to thesimplicity of design and installation. Manifold with compact tapping connections offers:–– guaranteed accuracy of positioning and installation ofthe tapping points–– reduced possibility of impulse line problems Choice of two discrete Beta ratio values simplifies thesizing and selection process Optional design with replaceable orifice plates enableslow-cost repair or, when process conditions change, reranging of the meter Optional element centralizing system ensures meter isconcentric with its pipe, thus avoiding significantadditional metering errors Available in either single-hole (concentric) or multihole(conditioning plate) formats Optional remote mounting kit to enable use at highertemperatures, where a compact transmitter would bedamaged by excessive temperaturesFig. 1Fig. 20only 30 % of the differential pressureis recovered with a standard orifice50100Standard orifice plates generate significant eddies and pressure lossesPercent of maximumpressure differenceFPD175 incorporates the following features: A wafer-bodied orifice carrier assembly with integralorifice plate and corner tapping points Integral welded 3-valve or 5-valve manifold Integral welded connections between the carrier tappingsand manifold Can be site-mounted to any conventional DP ormultivariable transmitter Optional conditioning orifice plate Optional removable orifice plate Version for remote-mounted transmitterPercent of maximumpressure difference—Compact orifice primary element070 % of the differential pressureis recovered with a balanced orifice50100Balanced orifice conditioning meter reduces eddies and pressure losses Upstream and downstream straight pipe lengthrestrictions reduced–– can be used without any straight pipe where conditionsdictate Reduced pressure losses–– compared to equivalent concentric plate, reducespressure loss by 50% Reduced noise levels–– compared to equivalent concentric plate Self-venting and draining–– no need for vent or drain holes–– improved handling of small amounts of entrained solids Improved accuracy–– accuracy of balanced flow meter (BFM) is improved by54 % compared to a standard square edged orifice plate
