The AMETEK Float Switch family is made up of model series F8300, 610XXX and 8TJ143XXX. These devices open or close an electrical circuit at a predetermined level of liquid. They have been developed primarily for use in aircraft fuel and lubrication tanks but are equally suited for many industrial applications in remote and non-accessible locations where liquid level control is important. Various installation modifications of the unit can be used to determine when a tank is filled to capacity, to indicate when a specific amount of liquid has been expended, or to indicate when a predetermined level has been reached.
