FlexStream - - Gas Standards Generator Brochure

OperationThe FlexStream™ is built around a microprocessor-controlled, stand-alone Base Permeation Tube System.This unit provides a temperature controlled permeation tube oven, dilution flow controls and front panel touch-screen interface. The FlexStream™ can use all Trace Source™ permeation and diffusion tubes. Mixturescontaining up to 8 components are possible using disposable permeation tubes in the stand-aloneFlexStream™ unit. Concentrations from below 1 ppb to over 1000 ppm are possible using disposable perme-ation tubes in the stand-alone FlexStream™ unit. Concentrations from below 1 ppb to over 1000 ppm are pos-sible using appropriate permeation tubes. Concentration from each tube can be varied over a 20:1 range byadjusting dilution flow. Three output modes are possible: Standby, where the permeation tube is held at operating conditions with thepermeate flowing to vent, Zero, where only the dilution flow is emitted to verify zero response, and Span,where the permeation tube output is added to the zero flow to create a known concentration Span mixture.An internal microprocessor with touch screen interface is used to control the operating mode and adjustdilution flow to achieve desired concentrations. The FlexStream™ can also be controlled remotely by a PC orprocess computer using Modbus® connectivity. Combining the Base Unit with other FlexStream™ modulesallows the system to create complex gas mixturesDescriptionThe new FlexStream™ automated Perm Tube System offerstotal flexibility for creating precision gas mixtures. Mixtures areproduced by diluting the miniscule flow emitted from TraceSource™ permeation (or diffusion) tubes with a much largerflow of inert matrix gas, typically nitrogen or zero air. TheFlexStream™ is ideally suited for creating trace concentration– ppm, ppb, and pptr – mixtures. The FlexStream™ BasePermeation Unit is small, easily transportable and easilycombined with other FlexStream™ modules to form integrat-ed gas mixing systems.KIN-TEKThe Calibration SpecialistsFlexStream™AutomatedPermeation Tube SystemKIN-TEKThe Calibration Specialists1-800-326-3627Ph: (409) 938-3627Fax: (409) 938-3710www.kin-tek.comemail: sales@kin-tek.comFEATURES• Complete, integrated, ready-to-use turnkey system• Automated operation with direct readout of concentration• Modes of Operation: standby, zero, span and purge• Touch-screen interface for local setup and manual control• Modbus connectivity for integration with existing systems• Designed for expandability• Flow path designed for maximum flexibility with minimum error• Flow path suitable for reactive gases - mixture contacts only glass, Teflon® and stainless steel (other materials available)• Accepts disposable permeation tubes, diffusion tubes, ultra-high rate liquid filled tubes, wafer tubes, and prefilled gas fed permeation tubes• Accepts up to 8 disposable tubes with maximum 6 inch length x 1 1/4 inch diameter (KIN-TEK HRT, SRT and EL tubes)• Accepts one of KIN-TEK refillable LFH, ULED and 57 Series tubes• High mass oven with electronic PID control• Temperature Control Range: 5 ºC above ambient from 20 to 150 ºC (heat only)• Temperature Setpoint Resolution: 0.01 ºC across control range• Temperature Display Resolution: 0.01 ºC on front panel touch screen• Standard Flow Range: 0.25-5.0 liter per minute• Optional Flow Ranges: 0.1-0.5, 0.1-1.0, 0.5-10.0 liter per minute• Flow Control over Calibrated Range: = ±1.5 % of reading• Flow Change - 0 to Full Scale: < 10 sec (2 time constants) at ambient pressure• Mode Change - Zero at 1 lpm to Span at 1 lpm: < 5 sec (2 time constants) at ambient pressure• Output Concentration Range: below 1 ppb to over 1000 ppm depending on emission rate and dilution flow rate• Local Interface: color touch screen display with virtual keypad• Remote Interfaces: RS-232 and Ethernet• Communication Protocol: Modbus RTU• Power Requirements: Standard: 115 VAC, 2 A• Power Requirements: Optional (specified at time of purchase): 230 VAC, 1 A• Dimensions: 7.5 inch Width x 13.5 inch Height x 20 inch Depth (add 3.5 inch to Depth for front panel inlet filter clearance)• Weight: Approximately 30 lbsBENEFITSTECHNICAL• Trace concentration mixtures for reactive compounds• Applicable to a wide range of compounds (over 500)• PPM and PPB mixtures with single step dilution• Calibration even for some reactive mixtures• Dynamic blending + immediate use eliminates storage degradation• Simplifies complex mixture preparation• Concentrations traceable to NIST (through physical variables)OPERATIONAL• Simple operation• Automated calibrationsECONOMIC• Save space – one unit replaces many gas cylinders• Reduce cost of multi-point calibrationSAFETY• Replaces high pressure gas mixture• User deals with only very small quantities of analyte compoundsRepresented by:Rev BASE.030311Copyright© 2011 KIN-TEK Laboratories, Inc.All rights reserved.
