It does away with clunky mechanical floats, and easily interfaces with electronic control systems. What differentiates this from our other eTape Liquid Sensors is the hard plastic jacket that makes it less susceptible to damage. The eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is
