Abstract: A fluid level indicator strip measures the level of water in a closed receptacle containing a volume of fluid within an impermeable liner. The strip is a flexible, thin and impermeable elongate strip having a first pressure sensing part disposed vertically within the receptacle on the surface of an inside wall and a second visual display part disposed on the same wall outside surface. The first and second parts are connected by a third horizontal part. Each pressure sensor is electrically connected to a direct opposite and corresponding visual display. In one embodiment the pressure sensors are piezoresistive. In another embodiment the visual displays are LEDs.
