公司歷史
1925年Barton Jones及其合作伙伴創(chuàng)立了Barton
Instruments公司,開(kāi)始只生產(chǎn)空氣冷卻器。

1943年BartonJones發(fā)明了liquid-filled,dual-bellows單元。這種干燥型的防爆元件在流量測(cè)量、液面測(cè)量及壓差測(cè)量方面是一個(gè)全新的概念。這導(dǎo)致了Barton核心產(chǎn)品的推出即壓差單元。dual-bellows儀表一直作為機(jī)械式壓差測(cè)量產(chǎn)品的工業(yè)標(biāo)準(zhǔn)。
1949年BartonInstrumentsCorporation成立。到現(xiàn)在,Barton已生產(chǎn)各種各樣的產(chǎn)品,但Barton卻一直在生產(chǎn)壓差式儀器。
1955 年Barton銷售公司成立,它是一個(gè)獨(dú)立的商品經(jīng)銷代理組織,它也分布在各個(gè)工業(yè)城市。
1963 年Barton購(gòu)買(mǎi)了FlowEquipmentCompany,這個(gè)公司主要生產(chǎn)positivedisplacementmeters,這種儀表廣泛應(yīng)用于石油工業(yè)。
1964年Barton購(gòu)買(mǎi)了兩家它的銷售代表處,即位于德克薩斯及休斯頓的SnyderCompany以及OilfieldServices,Inc。
1964 Barton Instruments Corporation被國(guó)際電報(bào)電話公司(ITT)購(gòu)買(mǎi)。
1979在英國(guó)成立子公司,負(fù)責(zé)Barton產(chǎn)品在歐洲和中東地區(qū)的銷售。
1985年Barton獲得另一個(gè)子公司,這使得Barton在工業(yè)方面擴(kuò)大了它的銷售渠道,如化工、發(fā)電、核電及造紙。
1998 ITT Barton歸屬于AmericanCommercialHoldings成為BartonInstrumentSystems,LLC,一個(gè)獨(dú)立的公司,為過(guò)程控制工業(yè)生產(chǎn)**測(cè)量?jī)x器。

Chart Recorders
Model 199 Differential Pressure Unit

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.

TURBINEMETERS 
NuFlo?LiquidTurbine Meters

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.

Low-PowerPreamplifier

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.

The NUFLO Series 1000 Watercut Monitor isasolidstate electronic instrument that determines thepercentwatercut inan oil emulsion without requiring thephysicalseparation of thefluids. The capacitance probe techniqueemployedby the WatercutMonitor allows the emulsion stream tobecontinuously surveyed. Thefrequency generated by thecapacitanceprobe oscillator is determinedby the watercut of theemulsionstream in the probe. The WatercutMonitor compensates forthenon-linear relationship between frequencyand watercut bystrictlydigital techniques. The result is a 4-20mAoutput signalwhichvaries linearly with watercut. The 4-20mA outputof theWatercutMonitor may be a completely floating signal becauseof theuse ofoptoisolation circuitry. This mode of operationrequirestheoptional isolating power supply board or the use oftwoexternalpower supplies. The Watercut Monitor may be operatedwith asingleexternal power supply if a floating output signal isnotrequired.

 
SAMPLERPRODUCTS
True Cut "C" Series Samplers

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.

 
TrueCutLS-1 Simultaneous Fill System

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.

 
TrueCutE-24 Batch Sampler Controller

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

TrueCutCS-1 Sampler
The True Cut CSSamplercapturesproportion-to-flow samples of flowing liquids inasimple,cost-effective operation. The sampler body containsanaccumulatorchamber for collecting the sample, a 1/4-in.sampleinlet port, anda solenoid valve actuator. When a flowmeterormeasurement controlsystem sends an electrical pulse to thesolenoidvalve, the CSaccumulation chamber connects to the flowstream, andtheinstrument obtains a sample. When the samplerisde-energized,typically after 1.5 to 2 seconds, the sampleisdischarged into thesample receptacle. The CS Sampler isavailablein two pressureranges to meet a wide range ofapplications. Theinstrument is easyto install and easy to maintain.Various timersfor controlling CSsamplers are also available.
 
LGS-1500SamplingSystem
The LGS-1500 Sampling System isanelectronicsample controller with an integral liquid/gassamplepump. Forliquid service, the sampler is pneumaticallyoperated byacustomer-supplied air source. For gas service, aninternalpressureregulator rated for the full range of pipelinepressureprotectsthe sampler from pressure spiking. The samplertransferssamplesinto a vented sample receptacle or apressure-balancedpistoncylinder. A block valve manifold allows easyconnection toprocesspiping, including fast-loop connections, andincludes twoneedlevalves to isolate the sampler from processpiping. Thecontrollerautomates the sampling process and is easilyconfiguredto operateas a timer or a pulse counter toallowproportional-to-time orproportional-to-volume sampling.
