LevelGuard® Liquid Level Pump Switch Sensor

CHALLENGE

Methode was asked to develop a more reliable way to prevent basement flooding due to the inaccuracies and failures of standard float switches, commonly used in residential sump pumps.

SOLUTION

placeholder

Methode's team designed a sensor switch that uses field-effect technology to monitor fluid levels within residential sump and sewage pits. LevelGuard® is a software free, solid state pump switch that turns your sump or sewage pump on and off. The field-effect of a touch cell detects any conductive mass (water) entering or changing the field and activates the pump evacuating the water from the pit. The field-effect sensor emanates through any dielectric substrate such as glass or plastic. Field-effect touch cells can be easily integrated in any kind of application and are the perfect sensor solution for fluid level control.

STORY

Dissatisfied with industry standard float switches, homeowners requested a more reliable means of preventing basement flooding. Methode's design team addressed owners' concerns and developed the LevelGuard® solution. With the market's first high-current pump control, LevelGuard utilizes patented field-effect sensing technology. Including upper- and lower-level fluid-sensing limits, thermal protection and easy installation mounting features, the solid-state solution met the challenge and surpassed competing float switch alternative 7 to 1 in independent testing.
