  • Coolant filter with coolant additive sensor
    Patent number: 6098575
    Abstract: A replaceable coolant filter assembly includes a housing, a filter element having and an end plate to define a fluid path through said filter and comprising a coolant additive sensor having a sacrificial sensing element disposed within said housing in contact with said fluid path. An electrical circuit connecting a microprocessor to the sensing element is grounded through the filter housing to an engine, the microprocessor being responsive to the opening of said sensing element circuit by corrosion an alarm device.

  • Resettable coolant additive maintenance sensor
    Patent number: 5647305
    Abstract: An engine coolant additive sensor comprises two sections, each made of dissimilar metals which have a single point of contact therebetween. A closed circuit is formed through this point of contact and such point is placed into the engine coolant. When additives become depleted in the coolant, corrosion of one metal takes place breaking the closed circuit and creating an indication that coolant additive maintenance is required. Once maintenance is performed, the point of contact is reestablished, resetting the circuit.
