7. A method for monitoring tubing conditions during feeding into a conduit comprising:
feeding tubing into the conduit via a tubing feed system comprising:
an injector head that directs the tubing into the conduit,
disposing a tubing measuring device between the injector head and the conduit; and
monitoring the condition of the tubing with the tubing measuring device comprising:
a collar configured to be fitted around the tubing; and
a plurality of sensors comprising:
a plurality of ultrasonic transducers,
wherein the plurality of ultrasonic transducers continuously measure a thickness of the tubing,
wherein the plurality of ultrasonic transducers continuously monitor for defects, and
a plurality of fingers oriented radially inward from the collar, wherein the plurality of fingers continuously measure the outer dimensions of the tubing, and
a computer system configured to:
receive data continually from the plurality of sensors, and trigger an alert based on the data received from the sensors.
