ULTRASONIC FLOW METERING SYSTEM

摘要

A system for determining the density, flow velocity, and mass flow of a fluid comprising at least one sing-around circuit that determines the velocity of a signal in the fluid and that is correlatable to a database for the fluid. A system for determining flow velocity uses two of the inventive circuits with directional transmitters (10, 110) and receivers (20, 120), one of which is set at an angle to the direction of flow that is different from the others.
