Apparatus and method for measuring mass flow rate of a moving medium

摘要

A mass flow meter is provided for measuring the mass flow rate of a material moving along a flow path. The mass flow meter generates a field of electromagnetic energy through which a material moving along the flow path passes. The mass flow meter includes a receiver that detects an amount of electromagnetic energy reflected from the material which is proportional to the concentration of material moving along the flow path. The amount of electromagnetic energy reflected and an assumed velocity are used to generate a response related to the mass flow rate of the material moving along the flow path.
