12" eTape Liquid Level Sensor + extras _ARD_SHIELD_SERIAL power managementThe eTape Liquid Level Sensor is a solid state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. The eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed. This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid.
