ABSTRACT:
A method and apparatus measures the gas bubble content of a flowing fluid on a continuous basis without extracting a sample of the fluid. A flowing fluid flows into a density sensor via a temperature and pressure sensor where the temperature, pressure and density of the fluid are determined. As the fluid exits the density sensor, a second pressure sensor determines the pressure of the exiting fluid. The outputs of the sensors are amplified and then input into a data processor. An operating panel supplies required constant data regarding the fluid and gas. The data processor calculates the gas bubble content using the above information in accordance with a predetermined formula.
