A recently granted patent (Publication Number: US11913908B2) discloses a system designed to monitor wear on well equipment components exposed to erosive fluid flows during operation. The system includes a wear transducer with a metal coupon and an ultrasonic sensor that transmits and receives signals to estimate wear. The ultrasonic sensor is housed within the metal coupon and includes a transmitting crystal, a receiving crystal, and a layer of acoustic gel for accurate wear measurement.

Furthermore, the system incorporates a controller to analyze data from the ultrasonic sensor and estimate the amount of wear on the well equipment component. The patent also describes a method for coupling the wear transducer to the equipment, exposing it to erosive fluid flows, and using ultrasonic signals to estimate wear. The method includes measuring the time between signal transmission and reception, detecting changes in the metal coupon's length, and predicting the remaining duty cycle for the equipment based on wear estimates. This innovative system aims to enhance maintenance practices and prolong the lifespan of well equipment components exposed to harsh operating conditions.
