A device was designed, built, calibrated, and installed in a small shallow lake for the detection and measurement of water movement at low velocities in natural environments. The device used sets of typical strain gauges in a full‐bridge configuration positioned orthogonally with respect to each other and in an array to receive multiple signals. Standard analog to digital detection and recording, via simple computing techniques, was used. This article also reports the first directly measured slow flow directionality of shallow water movement in the three coordinate system and its conversion to cylindrical and spherical systems.
