ABSTRACT:
A paraffin monitor apparatus responsive to changes in resistance includes a plurality of paraffin sensing means which are placed in a liquid medium containing paraffin. The paraffin sensing means are housed in a non-metallic, hard material having a plurality of channels so that each paraffin sensing means has at least one surface substantially in conformity to a surface of the non-metallic, hard material. A predetermined length of tubing is affixed to the non-metallic, hard material, and a plurality of wires, each of which passes through a channel of the non-metallic, hard material and the tubing, connect with corresponding paraffin sensing means. An adapter affixed to the tubing permits insertion of the non-metallic, hard material and a portion of the tubing into a pipeline containing a flowing liquid medium having paraffin. A manually operative switching device connected to the paraffin monitor apparatus and to the plurality of paraffin sensing means by the plurality of wires allows selection of pairs of paraffin sensing means to be connected to the paraffin monitor apparatus so as to monitor paraffin buildup at different locations in the flowing liquid medium.
