Zusammenfassung:	An ultrasonic sensor probe (100) and controller (109). The controller (109) is operationally configured to determine and display wet and dry status of each of a plurality of ultrasonic sensors (156) positioned in the barrel (123) of the probe (100). The controller (109) may change the status of a sensor (156) from wet to dry or dry to wet if certain conditions are met, such as the sensor (156) consistently indicates the new status over multiple readings or over a predetermined period of time. The controller (109) preferably includes a two-wire output capable of producing a stepped analog or digital signal that indicates the fluid level in a container in which the probe (100) is positioned.
