A system for measuring topography of the surface of a ground engaging tool is disclosed. The system may include a machine and the ground engaging tool. A phased array ultrasonic sensor may be associated with the ground engaging tool and configured to create ultrasonic pulses within the ground engaging tool. A communication device may be associated with the phased array ultrasonic sensor. A monitoring component may communicate with the phased array ultrasonic sensor via the communication device, and may be configured to receive signals from the phased array ultrasonic sensor and monitor the topography of the ground engaging tool.
