Abstract
The invention utilizes a segment of thin wall tubing which has an inlet, an outlet and a central region therebetween to measure flow. The central region is provided with two zones of different area. The meter is provided with a means to measure the elastic deformation of the tube in the two zones which results from the varying fluid flow and pressure. An output means is provided which evaluates the first and second zone deformation signals to generate a fluid mass flow output. Alternative embodiments include means to measure the elastic deformation of the tube to determine fluid density so that fluid mass flow may be determined when pressure and density are unknown.
