Abstract
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.
Claims30
A fluid sensor for sensing at least one characteristic of a fluid, the fluid sensor comprising:
- a sensing area;
- a sensing element configured to sense a characteristic of fluid located within the sensing area;
- and
- a mesh positioned around the sensing area, the mesh 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 sensing area.
A method of preventing gas bubbles in a sensing system for sensing a fluid contained in a tank, the sensing system including a sensing area and a sensor, the method comprising
- coupling a mesh to the sensing system, wherein the mesh covers the sensing area;
- allowing a liquid portion of the fluid to enter and exit the sensing area through the mesh;
- prohibiting a gas portion of the fluid entering the sensing area;
- and
- sensing a characteristic of the fluid contained within the sensing area.
A sensor operable to sense a characteristic of a fluid, the sensor comprising:
- a sensing area configured to contain the fluid;
- a filter covering the sensing area, the filter 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;
- and
- a transducer 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.
