System including a sensor configured to be disposed within a reservoir of a machine having moving parts that are lubricated by a liquid in the reservoir. The sensor is configured to obtain a measurement of the liquid that is representative of at least one of a quantity or quality of the liquid in the reservoir. The system also includes a device body operably coupled to the sensor. The device body has a processing unit that is operably coupled to the sensor and configured to generate first data signals representative of the measurement of the liquid. The device body also includes a transmitter that is configured to wirelessly communicate the first data signals to a remote reader.

Measuring sensor, in particular of a level of a liquid, in particular for the lubricating oil of an internal combustion engine, the sensor comprising a body with a longitudinal extension with at least one related intermediate portion having cylindrical symmetry with respect to said longitudinal extension and a bushing internally complementary to said intermediate portion, so that said body can freely rotate in the bushing with respect to said longitudinal extension and wherein the bushing externally comprises fixing means for fixing the sensor to an opening of a container of said liquid.

A level sensing apparatus (110) for attachment to a sounding tube to measure levels of content in a tank. The level sensing apparatus includes a housing (16) for enclosing components of the level sensing apparatus (20). These components include a transmitter and an antenna (18) operatively connected to the transmitter for directing electrical or mechanical waves in a direction away from the transmitter. The antenna is adapted to also receive electrical and mechanical waves. The apparatus further includes a sounding tube adaptor (32) sized for attachment to a sounding tube, and a connector assembly operatively attaching the housing to the sounding tube adaptor. The connector assembly enabling the housing to rotate relative to the sounding tube adaptor about a horizontal axis to expose an open end of the sounding tube. In use, the level sensing apparatus allows for pulse radar measurement of liquid levels in the tank. The housing may be rotated relative to the sounding tube to also allow for manual level measurements or sampling of the tank contents.

The invention relates to the field of measurement technology, and specifically to methods for monitoring the filling of railway tanks with liquid products, petroleum, petroleum products, petrochemical products, and food products, and may be used for monitoring the level to which railway tank cars are filled during the loading of liquid products itself in order to avoid (prevent) the overfilling or underfilling of tank cars. A method for monitoring the level to which railway lank cars are filled during the loading of liquid products is characterized in that, prior to beginning to fill a tank, a calculated tank loading level (H.sub.1) is determined on the basis of the calculated temperature (t°.sub.calculated) of a product to be loaded, the calculated loading level (H.sub.1) is marked with the help of a load level monitoring device, which device includes a rod having a bar which is mounted at the calculated loading level (H.sub.1), and which device is positioned within the tank. The next step involves visually monitoring the moment at which the level of the product to be loaded reaches the calculated loading level (H.sub.1) marked by the bar. During loading of the product, a thermal imaging device is used for measuring the actual temperature (t°.sub.current) of the product to be loaded, wherein the calculated tank loading level (H.sub.1) is adjusted if the actual temperature (t°.sub.current) increases or decreases relative to the calculated temperature (t.sub.calculated). A device for monitoring the level to which railway tank cars are filled during the loading of liquid products includes, positioned inside a tank, a rod with a bar, which bar is mounted at the calculated tank loading level (H.sub.1), and a thermal imaging device, intended for measuring the temperature of the product to he loaded. The technical result consists in increasing tank loading precision by monitoring the actual temperature of a product to be loaded, and adjusting a calculated loading level if the temperature changes relative to the calculated temperature.

An oil level gauge device in which an oil level gauge is inserted in a guide pipe communicating with an oil pan, is provided. In the oil level gauge, a cap having a plug configured to fit on an inner peripheral surface at one end portion of the guide pipe, and a flange integrally formed with the plug and abutted with the one end of the guide pipe, is provided. A groove extending from a deeply inserted side of the plug to an abutment surface of the end abutting the flange is formed in the inner peripheral surface. When the plug is fitted on the inner peripheral surface, a ventilation passage for communicating the inside and outside of the oil pan through the guide pipe is formed between the plug and the guide pipe by the groove.
