A method of detecting accumulation of material deposits within a fluid flow conduit includes providing, by a controller, an excitation signal to a heating element of the fluid flow conduit. The method includes obtaining, by the controller, thermodynamic data of the fluid flow conduit in response to providing the excitation signal, where the thermodynamic data includes heat flux data, diffusivity data, time data, temperature differential data, or a combination thereof. The method includes determining, by the controller, an amount of material deposits based on the thermodynamic data.

Systems and methods for detecting the presence of deposits in fluid flow conduits

A sensor for detecting material deposits in a fluid flow conduit includes a body and an array of pairs of temperature sensors disposed within the body, where each pair of temperature sensors is spaced a distance apart along a primary flow direction of the fluid flow conduit.
