Sensors, systems, and methods for measuring fluid perturbation are provided. One system includes a sensor module, a data management system, and a control system. In operation, data representing fluid is generated and recorded on the sensor module. During generating and recording, the sensor module is preferably partially submerged in a conductive fluid. The sensor module transmits the data representing fluid to the data management system in response to receiving data representing a record request from the data management system. Next, the data management system operates on the received data representing fluid to convert the data representing fluid into data representing fluid perturbation. Then the data management system stores the data representing fluid perturbation and transmits the data representing fluid perturbation to the control system. The control system stores the data representing fluid perturbation and displays the data representing fluid perturbation.
