Claims:WE CLAIM
1. A fluid monitoring device in a conduit, the fluid monitoring device comprising:
a depth camera placed inside the conduit, wherein the conduit has a first reference axis parallel to length of the conduit;
a conveyor belt placed in contact with a surface of a fluid in the conduit, wherein the conveyor belt is placed parallel to the first reference axis of the conduit, and wherein the first reference axis is perpendicular to a line that passes through a center of gravity of the depth camera and a center of gravity of the conveyor belt;
an indicator ball placed in contact with the conveyor belt; and
two image capturing devices placed inside the conduit, wherein the two image capturing devices are parallel to the first reference axis of the conduit, and wherein each of the two image capturing devices are placed at an equal distance from the depth camera.
2. The fluid monitoring device as claimed in claim 1, wherein the depth camera and each of the two image capturing devices are aligned along a second reference axis that is parallel to the first reference axis of the conduit.
3. The fluid monitoring device as claimed in claim 1, wherein the indicator ball travels along a third reference axis, wherein the third reference axis is parallel to the second reference axis and passes through the center of gravity of the conveyor belt along the length of the conduit.
4. The fluid monitoring device as claimed in claim 1, further comprises two movable arms, wherein each of the two movable arms is placed in a center of gravity of two pulleys of the conveyor belt.
5. The fluid monitoring device as claimed in claim 1, further comprises at least one light source placed adjacent to the two image capturing devices.
6. A method of monitoring fluid flow in a conduit, the method comprising:
determining, by a depth camera, a fluid level of a fluid in the conduit;
positioning, by two movable arms, a conveyor belt in contact with a surface
of the fluid based on the fluid level;
conveying, by the conveyor belt, an indicator ball at a rate proportional to a
flow rate of the fluid;
capturing, by two image capturing devices, plurality of images of the indicator ball when the indicator ball is in perpendicular line of sight of each of the two image capturing devices; and
monitoring, by a fluid monitoring device, the fluid flow in the conduit based on at least one of the plurality of images and the fluid level.
7. The method as claimed in claim 6, wherein monitoring the fluid flow comprises determining the flow rate of the fluid in the conduit based on each of the plurality of images.
8. The method as claimed in claim 7, wherein determining the flow rate comprises:
determining time difference between time at which each of the plurality of
images are captured; and
determining the flow rate based on the time difference and distance between the two image capturing devices.
9. The method as claimed in claim 7, wherein monitoring the fluid flow further comprises determining transferred fluid quantity based on the flow rate and volume data of the conduit;
10. The method as claimed in claim 9, wherein the volume data is determined based on radius of the conduit, length of the conduit, and fluid level of the conduit.
11. The method as claimed in claim 9, wherein monitoring the fluid flow further comprises determining presence of blockage inside the conduit based on at least one of the flow rate and the transferred fluid quantity.
12. The method as claimed in claim 12, wherein monitoring the fluid flow further comprises communicating at least one of the flow rate, the transferred fluid quantity or the presence of blockage to external devices.
13. The method as claimed in claim 6, further comprises illuminating inward side of the conduit by at least one light source.
