摘要： A capacitive sensor assembly for measuring a level of fluent material in a container includes an electronics section for receiving and processing signals and an antenna probe operably associated with the electronics section. The antenna probe has an electrical conductor and an insulating layer that covers at least a portion of the electrical conductor. The electrical conductor is connected to the electronics section. An enlarged measurement portion is in turn connected to the electrical conductor for detecting the presence or absence of the fluent material. The enlarged measurement portion has a surface area that is larger than a surface area of the electrical conductor over an equivalent height or length to function as a first plate of the capacitive sensor assembly, with the fluent material to be measured functioning as a second capacitive plate. In this manner, a change in detected capacitance of the antenna probe is reflective of a level condition of the fluent material.

摘要： A transducer for determining the liquid level within a container that is subjected to at least partial solidification at or below a freezing temperature is provided. The transducer includes a mounting head adapted for connection to the container, a liquid level sensor adapted for extending into the container from the mounting head; and a heating unit extending through the mounting head. The heating unit is constructed of at least one tubular member that surrounds or encircles the liquid level sensor. Heated fluid from a fluid source is circulated through the at least one tubular member for heating the contents of the tank at least within the vicinity of the liquid level sensor. A fluid withdrawal tube can also be in close proximity to the at least one tubular member so that the contents of the tank surrounding the heating unit can be removed even when the remaining tank contents are in a frozen state.

摘要： A method of determining level of a liquid between empty and full conditions within a container includes: providing first and second elongate capacitors, each capacitor being independently capable of measuring the liquid level at least between the empty and full conditions within the container, with the second capacitor being longer than the first capacitor; determining first and second capacitance values for the first and second capacitors, respectively, based on the liquid level height; and dividing the first capacitance value by a difference between the second and first capacitance values to thereby obtain a liquid level value independent of the dielectric constant.

摘要： A transducer for determining the level of liquid within a container includes a mounting head adapted for connection to the container and a sensor assembly adapted to extend into the container. A housing of the sensor assembly has a hollow interior that is isolated from liquid within the container. A plurality of sensor elements are located within the interior. A float rod is pivotally connected to the housing and a float is connected to a distal end of the float rod. An actuator located outside the housing is operatively associated with the float rod for pivotal movement therewith. The actuator is operative to change an electrical state of at least one of the sensor elements to thereby indicate a level condition of the liquid within the container. A snap-fit assembly of the mounting head and sensor assembly is also disclosed.
