Abstract

flow meter, comprising: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip chamber within the field of view; a laser configured to shine an optical light onto a binary optics assembly; and at least one processor operatively coupled to the image sensor, wherein: the at least one processor receives data from the image sensor having at least a portion of an array of lines represented therein, and the at least one processor estimates at least one parameter of liquid within the drip chamber using the data from the image sensor.

Claims (2)

What is claimed is:
1. A flow meter, comprising: a r adapted to couple to a drip chamber; a t member ively coupled to the coupler; an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip chamber and a back pattern within the field of view; a laser configured to shine an optical light onto a binary optics assembly; at least one processor operatively coupled to the image sensor, wherein: the at least one processor receives data from the image sensor, the data having at least a portion of the back pattern represented therein, and the at least one processor estimates at least one parameter of liquid within the drip chamber using the data from the image .
2. A flow meter according to claim 1, substantially as herein described or exemplified. 11’115 mammgng Emma mxw WW $me *3“ :éu Emzom: (mama?
