- Abstract:
- A simple, accurate, relatively compact and light gas mass flow meter has been developed with diagnostic capabilities. This fundamental mass flow meter concept revises a simple concept originally suggested four decades ago before the computer power existed to make a practical system. This paper revises the concept, discusses the development of a modern meter design and adds new diagnostic capabilities. The mass meters outputs are the volume flow rate, the fluid density and the mass flow rate. The system does not require the fluid density from an external source and can meter gas mass flows and measure gas density at low pressures. The system has significant qualitative diagnostics capable of signaling when the meter is malfunctioning. In cases where the fluid density is known from an external source some quantitative diagnostics are also available.
