18. A method of operating a monitoring system, the method comprising:
lowering an insert into a housing via a running tool;
emitting acoustic waves via a transmitter coupled to the running tool;
detecting portions of the acoustic waves via a receiver coupled to the housing;
receiving, from the receiver and at one or more processors, sensor signals indicative of the portions of the acoustic waves;
transforming, using the one or more processors, the sensor signals from a time domain into a frequency domain to generate a transformed signal;
comparing, using the one or more processors, a magnitude of the transformed signal to a threshold; and
determining, using the one or more processors, that the insert is in the landed position in the housing in response to the magnitude of the transformed signal exceeding the threshold.
