Abstract: A terminal, for use with a phreatic surface measurer having a tape measure with at least one sensor at one end of the tape measure, includes a flexible protection element that substantially surrounds the tape measure, and a coupler between the flexible protection element and the sensor, where the flexible protection element protects the tape measure along a part of its length without substantially impeding its flexibility. Optionally, two elements can be used and connected to each other by a connector. Also optionally, a breakaway feature can allow the replacement of terminals or portions thereof.
