BARTON Differential Pressure Units (DPUs) serve asactuatingunitsfor a wide variety of instruments. All modelsfeaturerupture-proofbellows.

Each DPU consists of a Bellows Unit Assembly (BUA)andremovablepressure housings. Within the BUA, flexible bellowsaresecured toa centerplate. In dual-bellows models, themovablebellows arerigidly connected by a dual valve stem thatpassesthrough thecenterplate. Valve seats, in the centerplatepassage,form a sealwith the valves. Contacting the valve stem inthecenterplate is adrive arm pivoted on the end of a sealedtorquetube. The bellowsis filled with a clean, noncorrosive,low-freezingpoint liquid. Arange spring assembly provides tensionagainstapplied pressures.In operation, pressure is applied to bothsidesof the bellows. Anydifference in pressure causes the bellowstomove until the springeffect (range springs) balances out theforce.The linear motion ofthe bellows (proportional to the DP)istransmitted as a rotarymotion through the torque tube.Indual-bellows units, if thebellows are subjected to a DPgreaterthan the unit’s DP rating, avalve closes and “traps” thefillliquid in the bellows — fullysupporting the bellows andpreventingrupture. Since opposingvalves are used, full protectionis providedin either direction.

NuFlo developed its first flowmeter for oilfieldapplicationsin1957. The meter incorporated a tungsten-carbide shaftandbearingto withstand the rugged conditions of theoilfieldenvironment.Over the years, this flowmeter has built anunsurpassedreputationfor withstanding severe punishment whilemaintainingoperationaland measurement integrity.

NuFlo turbine flowmeters indicate flow rate andmeasuretotalthroughput of a liquid line. As liquid flows throughthe meterandover the rotor, the rotor turns at a speed thatisdirectlyproportional to the flow rate. A magnetic pickup sensestherotorblades as they pass and generates an electrical (sinewave)signal.These electrical pulses are then transmitted totheflowmeasurement readout equipment.

The MC-II Plus WP Flow Analyzer is a weatherproofinstrumentwhichprovides a continuous display of instantaneous flowrateandaccumulated total volume of liquid or gas based on aturbineflowmeter input signal. It combines ease-of-use andfunctionalityfor atruly user friendly flow analyzer.

The liquid crystal display simultaneouslydisplaysseven-digittotals and six-digit flow rates, as well as aselectionof commonlyused engineering units for rate and volume.Thecalibration isimplemented by entering the calibration factor oftheflow meterand selecting the desired units of measurement.Itautomaticallycalculates its own divisor. When used with agasturbine meter, youinput gas calculation parameters and theflowanalyzerself-calculates the calibration factor for gas instandardcubicfeet. The unique combination of inputs andoutputsallowsflexibility of use in the field. The MC-II Plus WPFlowAnalyzerconnects to a turbine meter using quick disconnects.Ittakes theturbine meter signal directly in, without the useofpreamplifiers.A remote reset input allows the volume to beclearedvia a remotecomputer. The user can select either a 4- 20 mAoutputor anamplified flow meter frequency output to feed toremoteequipment.

The MC-II Plus Portable Rate Meter is aportablereadoutinstrument which provides a continuous display offlow rateandtotal volume of liquids and gases. Since it uses thesameadvancedcircuitry of the rest of the MC-II Plus familyofinstruments, itshares many of the same features.

Being portable, it can be transported to multiplefieldlocationsto verify proper operation of turbine flow meters ofanysize. Whenconnected to a NUFLO Turbine Flowmeter, the MC-IIPlusRate Meterbecomes an accurate system for the display ofcurrentflow rate andtotal volume.

The HFC-RTU Frequency Converter is designedtoprovidetransmission of flow meter information from remotemountedturbineflow meters to readout equipment.

The Model HFC-RTU is specifically designed for aturbineflowmeter and mounts directly on top of the flow meter. Itreceivesitssignal from the magnetic pickup and transmits a 4 – 20mAanalogsignal representing the flow rate of the meter. Theanalogsignaltravels on the same pair of wires that powertheinstrument.Adjustment potentiometers are provided for theinputsignalsensitivity, zero setting, and span setting. Rangeselectionismade via plug-in capacitors making calibrationandfieldadjustments extremely simple. The Model HFC-RTU is DCpoweredfrom12 to 30 VDC, depending upon the loop load resistance(seeLoadResistance vs. Power Supply). As such, the HFC-RTU canbeuseddirectly with most field RTU’s and computerapplicationsprovidingfor noise immune transmission of turbine flowmeterinformation.

Turbine flow meters  provide remote readings;however,noisyenvironments can cause erroneous or false readings attheremoteterminals. The easily-installed NUFLO LowPowerPre-Amplifier helpssolve the problem of noise when shieldedsignalcables cannoteffectively eliminate them. Electrical noisecancause erroneousreadings when the noise level equals or exceedsthemeter outputsignal amplitude, which generally is very low(inmillivolts). Theremote reading unit might also record noiseassignal output whenthe flow meter is not transmitting.

The Low Power Pre-Amplifier raises the turbine flowmetersignallevel at the metering point to a relatively high levelsignal(6-8volts). Thus, the receiver can discriminate betweensignalandnoise and register only true signals at the remotelocation.Theflow meter transmits its low level signal through apairofconductors to a remote reading unit. Shielded signalcablescanhelp keep noise out of this system or reduce thenoiselevel.However, a high noise level or the length of thetransmissioncablecan make shielding ineffective. The preamplifierhelpseliminatenoise problems in these instances.

C-Series Probe
The C-Seriesisokineticinlinesampling probe requires neither air nor hydraulicstocapturesamples. Rather, the probe is actuated by anelectricalpulse from acontroller, and uses existing pipelinepressure tofill the samplechamber with product. When the probe isactuated, asample chamberopens, allowing process fluid to flowthrough thechamber. As thewindow rotates, the sample is capturedin itsnatural state and fedby pipeline pressure to a receptacle.Byensuring that the processfluid is well-mixed and homogenouspriorto sampling, and using asampling process that collects thesampledirectly from the flowstream without changing the linearvelocityor direction of flow, thecustomer is assured of obtainingarepresentative sample.

Sample Probe Controller
The CDSeriesSampleProbe Controller controls the sampling frequency of CSeriessampleprobes. CD Series controllers are equipped with aninternal9- VDCmotor that rotates the sample probe 180° betweensample“grabs.”This design allows the C Series Sample Probe to takeasample witheach 180° rotation. While the controller canbepurchased without asample probe, it is useful only whenpairedwith a C-Series SampleProbe. The controllers are easilyattachedto the sample probe inthe pipeline and require no othermountinghardware. CD Seriescontrollers are available in fourdifferentconfigurations forcontrolling the sampling process withpulsecounts, timing, orpacing from a computer or PLC. Oneconfigurationcan be used totrigger an alarm to signal a loss ofpower, loss ofinput signal ormotor failure. The control cards inCD-20 A andCD-30 A controllerseach have four switches, which can beenabledto “read” flow interms of pulse counts or time (seconds).

The CD-20 B controller is most often used where PLCsorcomputersare used to pace the controller. This unit enablesonesample perpulse from a pre-scaled source. The CD-20 Balsoprovides anelectronic output signal to allow samples to becountedremotely orto verify motor rotation. The CD-20 SFA has theaddedfeature of adry contact for a controller failure alarm. Analarmis activated ifa sample command is not received within apresetperiod of time, themotor has not rotated within a presetperiod oftime, and/or poweris lost to the unit.

Installation Accessories
When apipelineisproperly fitted with a 2-in. ball valve and a U- 22unionadapter,the C Series Sample Probe can be safely installed inapipeline orremoved from a pipeline, even under pressure, withanA-3 sampleprobe retriever. A pressure equalizing valve (PEV)and/orLA-22line adapter may also be required in a C-Seriesprobeinstallation.

Many critical applications for sampling systemsrequireredundantor back-up verifications of quality orindependentanalysis of aseparate sample cylinder. True Cut? LS-1(SF) systemsare designedto fill two or more cylinderssimultaneously. Everytime this unitis activated, each cylinderreceives one sample.These units areoften used in gasoline blendingfacilities, but arecapable ofoperating in any light hydrocarbon. Aswith mostsampling systems,these units are designed for“proportional toflow” sampling andprovide repeatable sample grabsizes as well ascomplete purgecycles.

The True Cut? Model E-24 Batch Sample Controller isdesignedforproportional-to-flow, batch or time sampling. Theoperatorcanenter parameters via manual switches or downloadviaanRS-232/RS-485 Communication Loop. The controller provideslocalorremote display of flow rate, total flow (barrels, gallons,orcubicmeters), and total number of samples taken.

The unit's standard features include:
? Alarms
? Sample modes (flow, batch and time)
? Test mode
? Explosion-proof or weather-proof enclosures
