Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for leak detection from a thief hatch. An example thief hatch includes a vent control stem coupled to first and second sealing plates, the first and second sealing plates to control fluid flow through the thief hatch based on translation of the vent control stem, and an indicator extending from the vent control stem to provide a visual indication of a condition of the fluid flow.
Claims20
A thief hatch, comprising:
- a vent control stem coupled to first and second sealing plates, the first and second sealing plates to control fluid flow through the thief hatch based on translation of the vent control stem;
- and
- an indicator extending from the vent control stem to provide a visual indication of a condition of the fluid flow.
A thief hatch leak analyzer apparatus, comprising:
- a thief hatch position analyzer to determine an expected flow of a fluid through a thief hatch based on a state of the thief hatch;
- a leak determiner to compare a detected flow of the fluid through the thief hatch to the expected flow of the fluid;
- and
- an alert generator to generate an alert when a difference between the detected flow and the expected flow satisfies a threshold.
