31. Displacement Sensor for Detecting Sub-micrometer Motion
Topic: Metrology
Published: 7/6/2012
Authors: Svetlana Avramov-Zamurovic1, Jae M. Yoo, Nicholas G Dagalakis, Rae Duk Lee
Abstract: This paper describes the design of a nano displacement sensor that detects the presence of a moving platform by using fringing electric field. Its electrodes are commercially prefabricated Teflon insulated wires. This solution provides for excellent ...

35. TESTING LONG-WAVELENGTH ACOUSTIC FLOWMETER CONCEPTS FOR FLUE GAS FLOWS
Topic: Metrology
Published: 6/22/2012
Authors: Lee James Gorny, Keith A Gillis, Michael R Moldover
Abstract: As a part of NIST‰s program to standardize measurements of greenhouse gas emissions, we are developing a long-wavelength acoustic flowmeter (LWAF) for accurate, economical measurements of exhaust flows from coal-burning power plants. Measurements of ...

37. Improved Nozzle Manifold for Gas Flow Calibrations
Topic: Metrology
Published: 6/20/2012
Authors: Aaron N Johnson, Chunhui Li, John D Wright, Gina M Kline, Christopher J. Crowley
Abstract: We developed a new nozzle manifold that reduced the uncertainty of flow calibrations from 0.09 % to as low as 0.074 % for flows of air up to 0.84 kg/s (43 000 L/min at reference conditions of 101.325 kPa and 293.15 K). The nozzle manifold also reduc ...
