APPARATUS FOR MEASURING AND RECORDING ELECTRICAL RESISTANCE WITH A RECORDING DEVICE. PRODUCT COMPRISES OF A MONITORING DEVICE USED IN CONJUNCTION WITH SAND PROBES, (CLASSIFIED SEPARATELY), WHICH ARE USED TO DETECT SAND PRODUCTION AND EROSION FOUND IN OIL AND GAS PIPELINES. THE SAND LOG IS CONNECTED VIA A FIELD CABLE TO A FIELD INTERFACE UINIT, WHICH COMMUNICATES WITH A PC, EQUIPPED WITH PROPRIETRY SOFTWARE. THE SAND LOG MEASURES AND RECORDS THE ELECTRICAL RESISTANCE OF THE ELEMENTS THEREBY ALLOWING THE PC TO CALCULATE THE EROSION.
