This article is the second of a series describing how to perform liquid flow rate calibrations at fluid temperatures below +5 °C and above +90 °C. We examine the weigh standard method to measure the liquid mass flow rate and the assessment calculations of Measurement Uncertainty for Mass Flow at room temperature. The weigh standard method and assessment techniques need to be understood at room temperature before they are modified and assessed at higher and lower temperatures in future articles. Only then, can the weigh standard method be used to assess a Coriolis meter liquid mass flow measurement so that the Coriolis meter can be used as a master in-line flow reference for calibrating a paddlewheel/turbine meter from -40 °C to +200 °C.
