Abstract: A resistive liquid level/temperature sensor and transmitter (50) including low voltage impedance measurement circuitry to convert three impedance values into indications of the temperature and the levels of two (16, 18) different liquids (e.g., oil and water) located within a storage tank (14). A resistive chain network (40, 42) including a plurality of series connected resistors (R1... R5) and a corresponding plurality of reed switches (R1... R5) extend longitudinally through a liquid level sensing probe (10) that is dipped into the liquids in the tank.
