48 -- VALVES SOL n/a POC Fred Nicoletti, Principal Buyer, (925) 422-6726 E-MAIL: Clickk here to contact the contracting officer via, nicoletti1@llnl.gov. The University of California, Lawrence Livermore National Laboratory, is soliciting expressions of interest from firms who have designed and manufactured flow-rate metering systems incorporating 1) flow-rate meters using non-invasive ultrasonic techniques to detect and measure liquid flow in various pipes and 2) a computerized monitoring and data storage system to receive flow-rate data from multiple flow-rate meters installed throughout a piping system. The flow-rate meter must mount externally to existing pipes without modification, other than cleaning, of those pipes. The mechanical connection of the flow meter to the existing pipe must not promote a corrosive environment. The meter must operate within stated specifications for temperatures of the contained fluid within the pipe between 2 degrees and 90 degrees Celsius. The meter must operate when mounted to pipes of various, typical pipe materials with nominal outside pipe diameters between 1.9 cm and 10 cm. The precision and accuracy of liquid flow-rate measurements must be provided. The meters must provide signal data to a remotely located computer system. The output signal from the flow-rate meter should stream to the computer system for processing and storage to a file through a signal cable with a liquid-tight connector at the meter end. Indicate the maximum number of multiplexed flow-rate meters that can be accommodated within a single computer system. The computer system must be capable of multiplexing multiple flow-rate meter outputs with a unique address for each flow-rate meter. Describe how the system computes and signals flow-rates, including the average measurement time interval, and how it handles the zero flow state. Responses are required on or before 11/23/99. Facsimile responses will be accepted, fax number (925) 422-2973. Posted 11/10/99 (W-SN399866). (0314)
