A highly accurate and multi ranged centre zero voltmeter in conjunction with current interrupters to measure voltage gradients in the soil along the pipeline route. Localised changes in measured gradients indicate increased current flow and by deduction this usually means a coating defect is present. The accuracy of the instrument and the skill of the operator allows detailed investigation of the location and the collected data can be interpreted to categorise many defects along the route and prioritise on coating repairs.
