Fluid pressure is a derived measurand (N/m2) that is realized primarily through manometers and piston gauges at the NMI level. Piston gauges are becoming more useful as primary standards due to the ability to characterize the effective area, the most difficult variable to measure in a piston gauge, with enough confidence and low enough uncertainty to support the needs of an NMI or private laboratories with the need to resolve pressure at the highest level.
Fluke Calibration has introduced a piston gauge to be used as a primary standard to realize pressure in both gauge and absolute modes from 10 to 500 kPa called a PG9607. All variables in the pressure equation for a piston gauge were addressed in the design of the piston gauge to ensure the lowest uncertainty in pressure that could be attained.

Metrology revolves around standards—measurement standards, normative standards, standard measurement practices, etc.—to achieve consistent quality results. To remain competitive, metrology, like other industries, also depends on automation and standardized interoperability to attain and enhance that quality at reduced cost. Witness the long history of automated calibration software and the more recent laboratory management systems. But metrology encompasses more than just calibration and workload management: Consider documentation, uncertainty analysis, conformance testing risk analysis, service procurement, accreditation, interlaboratory comparisons and proficiency tests, specification use and development, product inspections, etc. How many tasks have we standardized and automated, and how many consume resources at every repetition? Why do we still handle paper calibration certificates and their PDF cousins, and manually search accreditation scopes? Why don’t our certificates contain full traceability chains? Do we provide customers obviously valuable services or just increase their overhead costs? This paper highlights some technological opportunities that the measurement community has not embraced widely, if at all, and suggests that more aggressive standardized information infrastructure adoption would help meet global economic and quality challenges.

High-speed clearance sealed piston provers for measuring gas flow rates have been available for over twenty years and have gained wide acceptance as a fast, cost-effective, primary calibration instrument for gas flow. High-speed piston provers are available for measuring flow rates from 0.5 sccm to 500,000 sccm with measurement uncertainties of up to 0.15%. This paper describes new advances in high-speed piston prover design.

Managing Measurement Uncertainty is the discipline of optimizing the uncertainty and cost of the measurements we make in the company. Without a systematic approach and the right tools, we are bound to make our measurements too good, too poor or too expensive – and we will not even know it!
Just the facts:
- The seminar focuses on the concept of uncertainty, where the uncertainty comes from and how you can control it.
- If you are comfortable using a calculator with a square root function, you have the mathematical background needed to get the full benefit of this seminar.
- There is no statistical theory, endless crunching of numbers or partial derivatives to worry about.
- You will learn how to use the knowledge you already have about your measuring processes to develop uncertainty budgets that can be used as a management tool to help you make informed decisions.
- You will learn how to start with a rough uncertainty estimate that can be generated in 5 minutes and refine it only to the extent it makes sense for your purpose.
- The seminar is based on the Guide to the Expression of Uncertainty in Measurement (GUM) and ISO/TS 14253-2
