Products within this category are used to measure or detect a fluid or material level within a container, commonly through the use of a buoyant element containing or connected to a switch of some type, but in other cases through the use of ultrasonic, optical, or other techniques. Outputs produced by these devices may be variable to allow a quantitative measurement of fluid/material level, or a simple binary indication of whether or not the level is in excess of some fixed value.
