Abstract

An apparatus includes a body and a fluid sampling conduit disposed within the body. The body is configured to be disposed within a pipe flowing a fluid. The fluid sampling conduit is configured to obtain a sample of the fluid flowing in the pipe. The apparatus includes an odometer wheel coupled to the body and an elastomeric ring surrounding at least a portion of the body. The elastomeric ring is configured to remove material disposed on an inner wall of the pipe as the apparatus travels through the pipe. The apparatus includes a solid sampling subsystem coupled to an external to the body. The solid sampling subsystem includes a capsule, an inlet valve, and a tubing. The inlet valve, when opened, allows at least a portion of the material removed from an inner wall of the pipe to flow through the tubing and into the capsule.

First claim

What is claimed is:

1. An apparatus comprising:
a body configured to be disposed within a pipe flowing a fluid, wherein the body comprises:
a first plate;
a second plate; and
a cylindrical housing extending from the first plate to the second plate;

a fluid sampling conduit disposed within the body, the fluid sampling conduit configured to obtain a sample of the fluid flowing in the pipe, wherein the fluid sampling conduit is disposed within the cylindrical housing and extends from the first plate to the second plate, the fluid sampling conduit comprising a first open end at the first plate and a second open end at the second plate;
an odometer wheel coupled to the body, the odometer wheel configured to measure a distance traveled by the body within the pipe based on rotating while contacting an inner wall of the pipe as the apparatus travels through the pipe, wherein the odometer wheel is coupled to an arm at a coupling point on the arm, the arm coupled to and extending from the body, the odometer wheel configured to rotate about the coupling point;
an elastomeric ring surrounding at least a portion of the body, the elastomeric ring configured to contact the inner wall of the pipe and remove material disposed on the inner wall of the pipe as the apparatus travels through the pipe; and
a solid sampling subsystem coupled to and external to the body, the solid sampling subsystem comprising:
a capsule;
an inlet valve coupled to the capsule; and
a tubing coupled to the inlet valve, wherein the inlet valve is configured to, when opened, allow at least a portion of material removed from the inner wall of the pipe by the elastomeric ring to flow through the tubing and into the capsule.

2. The apparatus of claim 1 , wherein the solid sampling subsystem comprises:
a housing coupled to the first plate, the capsule disposed within the housing; and
an outlet valve coupled to the capsule, the outlet valve configured to control flow of material out of the capsule.

3. The apparatus of claim 2 , wherein the arm comprises a first segment and a second segment connected to each other by a joint configured to allow rotation of the second segment about the joint in relation to the first segment, the first segment coupled to the first plate.

4. The apparatus of claim 3 , wherein the elastomeric ring is a first elastomeric ring surrounding a first portion of the cylindrical housing, and the apparatus comprises a second elastomeric ring surrounding a second portion of the cylindrical housing.

5. The apparatus of claim 4 , comprising an inertial sensor, the inertial sensor comprising at least one of a gyroscope sensor, an inclinometer, or an x-y-z accelerometer.

6. The apparatus of claim 5 , wherein:
the fluid sampling conduit is a first fluid sampling conduit, and
the apparatus comprises a second fluid sampling conduit disposed within the cylindrical housing, the second fluid sampling conduit extending from the first plate to the second plate, the second fluid sampling conduit comprising a first open end at the first plate and a second open end at the second plate.

7. The apparatus of claim 6 , wherein:
the odometer wheel is a first odometer wheel,

the first segment of the second arm is coupled to the first plate.

8. The apparatus of claim 7 , wherein:
the capsule is a first capsule,
the outlet valve is a first outlet valve,
the inlet valve is a first inlet valve,
the tubing is a first tubing, and
the apparatus comprises:
a second capsule disposed within the housing, the second capsule having an internal pressure less than atmospheric pressure;
a second outlet valve coupled to the second capsule, the second outlet valve configured to control flow of material out of the second capsule;
a second inlet valve coupled to the second capsule, the second inlet valve configured to control flow of material into the second capsule; and
a second tubing disposed along the second arm, at least one end of the second tubing coupled to the second inlet valve.

9. A method of using the apparatus of claim 1 , the method comprising:
measuring, by the odometer of the apparatus disposed within a pipe, a distance traveled by the body within the pipe;
obtaining and storing, by the fluid sampling conduit of the apparatus, a sample of fluid flowing in the pipe;
removing, by the elastomeric ring of the apparatus, material disposed on an inner wall of the pipe; and
obtaining and storing, by the capsule of the apparatus, at least a portion of the material removed from the inner wall of the pipe.

10. The method of claim 9 , wherein obtaining the sample of fluid occurs at a first location along the pipe, and measuring the distance traveled by the body within the pipe is repeated at the first location.

11. The method of claim 10 , wherein obtaining the portion of the material removed from the inner wall of the pipe occurs at a second location along the pipe, and measuring the distance traveled by the body within the pipe is repeated at the second location.

12. The method of claim 11 , comprising:
measuring, by an inertial sensor of the apparatus, a change in inertia of the apparatus within the pipe; and
determining a location of the body within the pipe based on the measured distance and the measured change in inertia.

13. A system comprising:
a pipe configured to flow a fluid; and
an apparatus configured to be disposed within the pipe, the apparatus comprising:
a body;
