Mass flowmeter apparatus and method.

摘要

This invention relates to a method and apparatus for a liquid mass flowmeter. The method comprises monitoring the amount of liquid in a reference container (2) and determining the flow rate as change in mass divided by elapsed time as fluid exits the container. The flowmeter apparatus gives correct flow regardless of changes in density, viscosity, or composition of the liquid and corrects flow in spite of errors common in currently used flowmeters, such as, calibration shifts, restricted orifices and/or bearing drag and blade wear of turbine meters.
