Abstract
Methods for Ultrasonic Flow Metering, Ultrasonic Flow Meter Calibration, and Ultrasonic Fluid Characterization. Focusing on the governing principles and equations of flow measurement for ultrasonic flow meters, using temperature referenced differential and absolute time of flight measurements to characterize fluid motion. As well as, experimental solutions to meter calibration constants, thermal expansion, concentration change in fluid validation/correction using a ratiometric approach comparing expected and measured zero flow measurements, change of fluid in process validation/correction using acoustic properties of a specific fluid, and zero flow correlations/validation based on time of flight and temperature, referenced to historically captured data and the acoustic properties of the fluid in the process.
