Fluid Flow Sensing and Bubble Detection Apparatus, and Methods for Improving Fluid Flow Sensing and Bubble Detection Apparatus

摘要

A fluid flow sensing and bubble detecting apparatus includes a housing provided with a cavity configured to receive a tube through which a conductive fluid flows, a housing supported by the housing, and a fluid flowing through the tube A fluid flow sensing and bubble detection electrical sensor assembly configured to sense the flow of and detect bubbles in the fluid, and an electrically grounded Electro-Magnetic Interference (EMI) disposed between the cavity and at least a portion of the sensor assembly. a shielding, wherein the EMI shield protects the sensor assembly from unwanted EMI emitted from a tube received within the cavity, otherwise the fluid flow sensing and bubble detection device generates false bubble detection signals. can do it
