Embodiment Construction

[0029] In the following, refer to figure 1 A first advantageous embodiment of a fluid sensor protection assembly 1 , designated below as "assembly 1 ", is described.

[0030] The assembly 1 can especially be used in a tank 3 for a solution 4, preferably a urea solution, such as Diesel Exhaust Fluid (DEF). Tank 3 is indicated by a dotted line. The assembly 1 may be provided with a fluid sensor 5 indicated by a dashed line. The assembly 1 and the fluid sensor 5 can together form a fluid sensor system 7 according to the invention.

[0031] The fluid sensor 5 can in particular be a mass sensor which is suitable for analyzing the mass of the solution 4 in the tank 3 . The fluid sensor 5 is preferably an optical sensor or an ultrasonic sensor. In the alternative, the sensor technology can be of any other type or combination of different types.

[0032] The assembly 1 comprises a housing 9 for receiving the fluid sensor 5 . Preferably, the housing 9 is also adapted to support a...

Abstract

The invention relates to a fluid sensor protection assembly for protecting at least one fluid sensor of a fluid sensor system against air bubbles and / or particles, in particular for protecting at least one urea sensor of a urea sensor system. In order to effectively protect the fluid sensors of the sensor system while being easy and cost-effective to manufacture, the assembly of the invention comprises a housing for receiving at least one fluid sensor, comprising a bottom wall and a top wall spaced apart from each other in the vertical direction, the bottom wall The wall is provided with at least one lower flow opening and the top wall is provided with at least one upper flow opening, the lower and upper flow openings being covered on the outside of the housing by lower and upper cover members respectively, each cover member being vertically aligned with the corresponding flow opening Spaced apart and provided with at least one outer flow opening, at least one continuous flow channel extends between at least one lower outer flow opening and at least one upper outer flow opening.

Description

technical field [0001] The invention relates to a fluid sensor protection assembly for protecting at least one fluid sensor of a fluid sensor system from gas bubbles and / or particles, in particular for protecting at least one urea sensor of a urea sensor system. Background technique [0002] Fluid sensor systems and corresponding sensor protection assemblies are known in the prior art and are commonly used in fluid tanks, especially in fluids such as urea solution (Diesel Exhaust Fluid, "DEF") for cleaning diesel engine exhaust. gas fluid tank. Other types of fluids in which the sensor protection assembly and fluid sensor system according to the present invention may be used are oil-based fluids. Fluid sensors are usually used to monitor certain properties of fluids to analyze the quality of solutions. However, certain situations may negatively affect the measurements. The first problem may be that some fluids tend to generate air bubbles during the movement of the tank. ...
