  • Subsea wellhead mechanical erosion detector
    Patent number: 5740863
    Abstract: A consumable probe is installed in an elbow zone of a well. The consumable probe is subject to ablation caused by abrasive particles suspended in the fluid being transported by the conduit. As the probe is ablated pressure sensitive chambers will be exposed and the pressure in the conduit will pressurize the pressure sensitive chambers and signal a readout station in a position remote from the location of the probe in the conduit.
