Abstract
The present invention is a system and method for determining the onset of scale in a pipeline carrying a petroleum liquid. A source provides electrical energy to a heating element in a housing adapted to fit in the pipeline. The housing also encloses a sensor for sensing the temperature of the petroleum liquid and providing a corresponding electrical signal. The housing is arranged with the heating element and the sensor in such a manner that there is heat transfer to and from the petroleum liquid so that as scale starts to coat the housing it affects the transfer of heat.
