J -- UPGRADE AND REWORK OF LIQUID AND GAS CALIBRATION SYSTEMS SOL F04700-95-RA012 DUE 051795 POC Ric Mones, Contract Specialist, (805)277-3900 Ext 2317. The Air Force Flight Test Center is seeking for a vendor to upgrade and rework of liquid (Flow Measurement Systems Model PDCL-400 GPM and Model PDCL-10X) and gas (Brooks Instrument Gaseous Flow Bell Prover Model 1091A) calibration systems. These systems are used to calibrate aircraft fuel flow meters and hydraulic fluid flow meters in Air Force test cells. Services on the Flow Measurement Systems Model PDCL-400 will include the repair, calibration or replacement of the following: a) Viscometer; model: Cambridge Applied Systems; range: 0.500- 300.0 centistokes; accuracy: +/- 2 percent of indicated value, b) Densitometer; model: Anton Parr Instruments with range: 0.200 - 2.000 specific gravity; accuracy: +/- 0.0143 percent of indicated value, c) Upgrade and install variable speed AC motor and controller with range: 0.4 - 400 gallons per minute, d) Upgrade and install valves and hardware for piston direction controls; investigation of possible installation of second shaft, e) Install analog counter/timer I/O and interface boards in Air Force supplied 386 DX (minimum of 100 M hard drive) computer with one parallel and two serial interfaces for calibration corrections and display, f) Inspection and certification of piston cylinder, and encoder in accordance with MILSTD 45662A and g) Calibration from 0.4 to 400 gallons per minute with accuracy of +/- 0.1 percent of indicated value and operate using Stoddard Solvents from 0 to 115 degrees Fahrenheit at 0.5 - 300 centistokes. Calibration must conform to MILSTD 45662A. Services on the Flow Measurement Systems Model PDCL-10X shall include the following: a) Installation of linear encoder, b) Inspection and certification of piston, cylinder and encoder in accordance with MILSTD 45662A and c) Installation of hardware for interfacing viscometer and densitometer. Services on the Brooks Instruments Gaseous Flow Bell Prover Model 1091A includes the following: a) Installation of an optical bar, rotary encoder, eletrically operated valves, regulator with loader, bell control valve manifold and an interface box (signal conditioner). In addition to the above, the proposed procurement calls for the furnishing of software to use Brooks Model 1091 to calibrate flowmeters including but not limited to thermal mass meters, laminar flow elements, sonic venturis, subsonic venturis, rotameters, turbine flow meters, positive displacement meters, coriolis meters, orifice, Vcone, variable area sonic venturi, vortex shedders. Software should allow calibrations from 0.28 - 1415 liters per minute with accuracy of +/- 0.25 percent indicated value. It also calls for the furnishing of an on-line real-time software with Strouhal and Roshko corrections for use with a) Model PDCL 400 GPM Liquid Flow Calibrator from 0.4 to 400 gallons per minute with accuracy of +/- 0.1 percent indicated value and operate using Stoddard Solvents from 0 to ll5 degrees Fahrenheit at 0.5 - 300 centistokes, b) Model PDCL-10X Liquid Flow Calibrator from 0.1 - 10 gallons per minute with accuracy of +/- .1 percent of indicated value. Software will be packaged and licensed to 412 CRS/LGRSL; IBM compatible series PC, user friendly menu driven; maintain a data base of all flow meters to be supported; maintain math formulas for all types of flow meters to be calibrated; provide spread sheet displays of calibration during process; display graphical representation of calibration plots including Strouhal and Roshko; provide printed calibration certificate with actual calibration values; maintain historical data base of all calibrations performed on all three calibrators; and monitor and correct for all possible liquid calaibrator error sources. Offeror must provide two identical software packages, one configured for the liquid calibrator and one configured for the bell prover. Offeror must provide complete uncertainty analysis for liquid calibrator. Under the authority of FAR 6.302-1 (Only one responsible source and no other supplies or services will satisfy agency requirements), AFFTC intends to negotiate a contract with Flow Dynamics Inc. unless responses to this notice reveal other sources capable of satisfying the requirement. Interested vendors must submit clear and convincing documentation including prices, past contract numbers, points of contact, and phone numbers, indicating that they can perform the proposed requirements. SIC CODE 8999. Size Standard is $5M. See Numbered Note(s): 22. (0101)
