Bubble detection system and method within a liquid flow of a pipe by sensing changes in local liquid pressure

Abstract

A system for detecting bubbles within a liquid flowing in an interior of a pipe. The system includes a system for detecting bubbles within a liquid flowing in an interior of a pipe. The system includes a pressure sensor affixed to the interior of the pipe and a microcontroller communicating with the pressure sensor. The pressure sensor gathers pressure readings of the liquid flowing in the pipe at the location of the pressure sensor and sends the gathered pressure readings to the microprocessor. A pressure differential range over a specific period of time is selected which when exceeded, indicates the presence of bubbles in the liquid flowing in the pipe. The pressure differential range is utilized by the microcontroller to determine the presence of bubbles in the fluid flowing through the pipe. The microcontroller determines a presence of bubbles in the liquid based on an exceedance of the pressure differential range from pressure readings gathered by the pressure sensor over the selected period of time.
