MECHANICAL MEASUREMENTS

A new approach to the assessment of interfering factors that arise in the process of diversion of a flow of liquid in the weighing device of a calibration device is presented. The uncertainty budget of the calibration device in reproduction of the unit of mass and unit of volume of liquid in a flow and unit of mass and unit of volume discharge of liquid is considered for this case. The operating principle of the calibration device is based on the method of static weighing. An assessment of the sources of uncertainty is performed by a pneumometric technique, which is itself based on an experimental determination of the local characteristics of the flow of liquid.
