摘要:
The present invention related to sensing device used for sensing the level of the liquid in a liquid storage system. The sensing device according to the invention is a non contact type and uses a float comprising a sensing device and a magnet. According to the level of liquid, the float assembly moves upwards or downwards and creates variation in air gap between the sensing element and a ferromagnetic member thereby obtaining output variations which is used to update the level of the fluid in the liquid storage from time to time.

A fluid level sensor assembly for monitoring a fluid level in a fluid collection canister of a medical waste fluid collection system. The fluid level sensor assembly includes a fluid level sensor configured for monitoring the fluid level in the fluid collection canister and a fluid level sensor cover configured for preventing direct contact between the fluid level sensor and a fluid in the fluid collection canister. The fluid level sensor cover includes a polymeric cap and polymeric sheath extending from the cap. The elongate tubular sheath surrounds an elongate probe of the sensor with the cap positioned at a base of a sensor body of the sensor to prevent direct fluid contact with the elongate sensor probe and the sensor body.

A sensor for measuring fluid level is provided that includes a float, which may be steel or another material that affects magnetic flux. The sensor further includes a housing defining a cavity configured to receive the float. The housing may be, but need not be, tubular, and the cavity may be cylindrical. At least one magnetic coil is wound to the housing along the cavity. The coil may be wound around the housing. The float is positionable in the fluid to move within the cavity in relation to fluid level.

The invention relates to a method for testing a container warning device of a compensation container (1), particularly for a hydraulic motor vehicle brake system. Said container warning device comprises a switching unit (7) with at least one reed contact (5) as a switching element. In order to be able to find all possible faults of the reed contact (5), a dynamic contact resistance and a transient response of the reed contact (5) are measured on the pre-assembled switching unit (7).

Bei einem Verfahren zum Überwachen der Qualität eines alkoholhaltigen Kraftstoffs in einem Lagertank (1), der einen Sumpfbereich (8) aufweist, wird die Dichte der im Sumpfbereich (8) des Lagertanks (1) befindlichen Flüssigkeit gemessen und mit vorgegebenen Werten verglichen, die die Dichte einer Wasser und Alkohol enthaltenden Mischphase als Funktion der Zusammensetzung charakterisieren.
摘要:
The invention refers to a device for visually indicating the liquid level inside a tank comprising a float partially immersed in said liquid and vertically movable in the tank, and a visualisation system of the level of said liquid, characterised in that said visualisation system comprises: a) an at least partially transparent visualisation container, suitable for being positioned outside said tank; b) a visualisation liquid; and c) a measurement tube in said tank around which said float slides, and in which a piston tightly slides and separates an upper part filled with said visualisation liquid and a lower part. Said piston is joined by magnetic coupling means to said float. Said piston moves said visualisation liquid into or out the visualisation container according to the vertical position of the float. An additional communication tube links said lower part to atmospheric air or to the upper part of the visualisation container filled with a service liquid having a specific weight lower than the on of said visualisation liquid.
