An apparatus and method for producing a substantially uniform bond line thickness by utilizing a crosshatch, grid pattern, or spacers of like patterns in a receptacle of a transducer housing. Certain embodiments include a housing configured to retain a transducer. The housing includes an annular wall and a receptacle adjacent to the wall. The receptacle has a member configured to allow radiation to pass through it. The member has a first surface and a second surface. The spacers on the first surface are configured in a grid pattern to maintain uniform spacing and a uniform bond line thickness between the transducer and the member. The bond line is further controlled by the depth of the spacers, which are configured to maintain a generally constant bond line thickness.

A sensor operable to sense a characteristic of a fluid. The sensor includes a sensing area, a filter, and a transducer. The sensing area is configured to contain the fluid. The filter covers the sensing area. The filter is configured to allow a liquid portion of the fluid to enter the sensing area and substantially prohibit a gas portion of the fluid to enter the sensing area. The transducer is operable to output a pulse of sound through the liquid portion of the fluid contained within the sensing area, receive the reflected pulse of sound, and output a characteristic of the fluid based on the received pulse of sound.

A fluid sensor for sensing at least one characteristic of a fluid. The fluid sensor includes a sensing area, a sensing element and a mesh. The sensing element is configured to sense a characteristic of fluid located within the sensing area. The mesh is positioned around the sensing area. The mesh is configured to allow a liquid portion of the fluid to enter and exit the sensing area, and substantially prohibit a gas portion of the fluid to enter the channel.

Systems and methods for defrosting sensing components in fluid sensing system. In one embodiment, the invention provides a defrosting system that includes a sensing system. The sensing system includes a sensor operable to sense a characteristic of the fluid in a tank. The defrosting system includes a fluid pickup line spaced apart from the sensor, and a fluid return line. The fluid return line includes an output. The output is positioned to direct fluid onto the sensing system. In one embodiment, the defrosting system further comprises a pipe configured to provide the fluid to a system external to the tank. The fluid is heated by heat generated by the external system and directed onto the sensing system at least partially defrosts fluid contained within the sensing system.
