An apparatus for measuring deposits in pipelines is disclosed. The apparatus consists of a fluid immersible body being sized and shaped to be insertable into a pipeline to at least partially block a flow of fluid past said body in said pipeline. Most preferably, the body is made from a compressible foam portion surrounding a fluid tight electronics chamber. Attached to the compressible body are sensors to measure a thickness of any deposits on the inside of the pipeline. The sensors are connected to data storage means to record the measurements. In a preferred embodiment, the thickness is detected by proximity sensors which sense the proximity of the metal pipe wall. The device is most preferably used for measuring wax deposit thickness. In another embodiment of the invention, there is provided a method for measuring wax deposition rates in pipelines comprising passing the apparatus for measuring deposit thickness through the pipeline on a first occasion, passing the same apparatus through the pipeline on a second occasion, and comparing the measured thicknesses to calculate a rate of change of deposit thickness over time. An another embodiment of the invention, there is provided a method of measuring deposits in pipelines comprising placing a sensing device in the pipeline, passing the sensing device through the pipeline, measuring the deposits in the pipeline and recording the measurements of the deposits in an electronic format.
