    摘要: A calibration system and methods for flow metering technologies integrates a known primary reference standard (e.g., a gravimetric scale), configured to determine a mass of calibration fluid, in parallel with surrogate secondary masters (e.g., Coriolis effect flowmeters) connected via an adjustable flowpath having a closed loop mode, including a meter bank, a pump and a measuring section, and an open loop mode, including a reservoir, the meter bank, the pump, the measuring section and the primary reference standard, which enables calibration duality and redundant meter under test confirmation of calibration factors. The disclosed systems and methods enable life cycle assurance of the primary reference standard and the secondary masters' standard reliability and reproducibility over time and, as a redundant system, enable calibration of multiple flow metering technologies, such as, for example, volumetric, mass, density, viscosity and Reynolds number-reliant technologies, in one homogenous system.

    摘要: A method for testing a device under test, the device under test being a measuring instrument to measure a physical parameter of a fluid, includes: performing a plurality of valid test runs, wherein a valid test run includes: exposing the device under test and a reference measuring instrument to the fluid under a set of influences, the set of influences being defined by influence parameters; monitoring the influence parameters; obtaining a reference value for the physical parameter from the reference measuring instrument; and obtaining a test value for the physical parameter from the device under test, wherein a test run is invalidated if influence parameters do not meet specified test requirements for the influence parameters; and then evaluating a plurality of test values originating from the plurality of valid test runs with respect to at least one of accuracy, repeatability and reproducibility.
