66 -- DIGITAL MASS FLOW CONTROLLERS SOL DE-RQ26-00NT0037 DUE 051600 POC Thomas J. Gruber, 412-386-5897 E-MAIL: robert.mohn@netl.doe.gov, thomas.gruber@netl.doe.gov. This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. The announcement constitutes the only solicitation: proposals are being requested and a written solicitation will not be issued. This solicitation document incorporates all provisions and clauses in effect through Federal Acquisition Circular 97-11. The solicitation number is DE-RQ26-00NTS00377 and is being issued, on April 14, 2000, as a Request for Quotations using Simplified Acquisition Procedures under FAR Part 13. Only written offers received by May 16, 2000 in accordance with the solicitation, will receive consideration and responses must convey the ability of the offeror to meet the stated requirements. The documentation shall include descriptive literature containing sufficient technical literature to establish a bonafide capacity of meeting this requirement. Request for information should be directed to ThomasJ. Gruber at 412-386-5897 or E-mail thomas. gruber@netl.doe.gov. The specifications for Digital Mass Flow Controllers (DMFC) to be provided under this procurement action shall consist of the following: All of the following specifications must be met for all 47 DMFC: General -- The DMFC must be a digital mass flow controller and must be able to regulate the flow of a variety of gases with maximum flow rates of 3 sccm (standard cubic centimeter per minute) to 2000 sccm. The DMFCs must be able to control down to at least 2% of maximum flow rate. These gases are N2, H2, O2, CO2, CO, H2S, SO2, HCl, and CH4. Each DMFC will be required to control only one of the gases and within a more specific range of flowrates. See the accompanying table for the specific DMFC/gas/maximum flowrate/gas pressure combinations. Physical -- Wetted parts must be stainless steel and seals must be of a material that is appropriate for the specific gas with special emphasis on the following corrosive gases: HCl, CO2, H2S, and SO2. A D-type connector for power and computer connections must be supplied on each DMFC. The DMFC must be able to operate in ambient and process temperatures of 0-50 C. Stainless steel 1/4 " tube compression connections must be installed on each DMFC. Computer Control -- Digital control by RS-485 is required to control functions and to report measurement of mass flow. Control by analog input/output can not be the primary method but must be available. The following functions must be able to be controlled by computer: gas flowrate, valve ramp rate, and analog or digital control of the DMFC. The DMFC must be able to report the amount of gas flowing to a computer and also must have the capability of reporting flowrate to either a built in display or an auxiliary display. Electrical -- The DMFC must be able to be operated at any voltage within the range of15-24 VDC. Current consumption should be no more than 400 mA per DMFC. The DMFC must have the ability to be recalibrated for different gases, different temperatures, and different input and output gas pressures. Each DMFC must have the ability to store at least 6 different calibration curves. Accuracy -- The accuracy of the flowrate of each DMFC must be better than 1% of full scale. Operations -- The DMFC must be capable of running continuous self-diagnostic routines. It must have adaptive valve controls that can compensate for changes in operating conditions. It must have an alarm that indicates both diagnostic and high/low flow errors. All calibrations must be done using primary standards that are traceable to NIST (National Institute of Science and Technology). Software -- The vendor must provide stand-alone software for computer control and monitoring by RS-485 and also provide a software interface to LabView software.
