ABSTRACT:
Disclosed is a Test Point Monitor (TPM) remotely coupled to a Test Point Interrogator (TPI) for the purpose of measuring and communicating cathodic protection voltage values from an object of interest, generally an underground pipeline. The TPM automatically measures cathodic voltage records them in its memory. A technician is guided towards the TPM by a handheld TPI. The TPI includes a GPS function, and when the technician is in range of the TPM, the TPI will call for the stored TPM data. The TPM is adapted for storing in its memory past voltage readings, and transmitting current and past voltage readings to the TPI. The TPI will store data from several thousand such TPM units for download into a main database via direct connection to the database, via wireless transmission, or via the internet.
