    Abstract: A remote terminal unit for use in monitoring a metallic pipeline can take an electrical measurement at the pipe and transmit the measurement in a modulated signal to a main measurement unit located along the pipe and distant from the remote terminal unit. The electrical measurement is taken at regular time intervals between a reference electrode electrically connected to the pipe and a coupon composed of a sacrificial corrosion material in order to monitor the pipe for possible corrosion. The electrical measurement is modulated with a low frequency carrier signal for transmission along the pipe, eliminating the need to take the measurements directly at physical locations along the pipe.
