Abstract

An optical sensor device configured for use in combination with a fluid flowing through a tubing, the optical sensor device includes a light source configured to emit a light, with at least a portion of the light being exposed to a fluid in the tubing and reflected, an optical sensor configured to receive at least a portion of the reflected light and analyze at least a portion of the received reflected light to determine a reflectance measurement, and a controller configured to correlate the reflectance measurement to an input particulate level and generate an output indicative of the fluid flow rate corresponding to the reflectance measurement. Also disclosed is a method of optically measuring fluid flow rate in a fluid processing system including optically monitoring fluid flow through a transparent portion of a tubing by measuring light reflectance of particles in the fluid.
