Definitions
- the claimed invention relates to the field of measuring equipment, and in particular to methods of controlling the loading of railway tanks with liquid products, for example, oil, petroleum products, petrochemicals, food products and can be used to control the level of loading of railway tanks directly in the process of filling liquid products to exclude (warning) overflow or underfilling of tanks.
- liquid products for example, oil, petroleum products, petrochemicals, food products
- a known method for remote detection of commercial marriage of oil tank cars of rail transport which consists in inspecting them on the train, in which the tank filled with oil products are moved in the field of view of the thermal imager, get their thermal image, compare the outline image of the tank with its scale image from the database, on the thermal image detect the level of filling the tank, compare it with the required, and then judge the presence of overflow or underfilling of petroleum products (patent RU2340946C1, publ. 10.0b.200b).
- the yards
- a disadvantage of the known methods is that with their help you can only control the actual level of oil products loaded in railway tanks, ready for transportation. These methods can be used, in particular, by the security services of oil refineries in order to suppress the theft of petroleum products. It is also possible to identify inconsistencies between the data on the quantity of the shipped product indicated on the consignment notes and the actual quantity shipped. Using the proposed device can "facilitate" the claim work when receiving fuel in tanks, since information about underfilling will be obtained before opening the tanks, which is important when considering a claim in the future. Moreover, the error in determining the level of loading is quite large, since during the movement of controlled tanks the liquid level fluctuates.
- the quality of the thermal image is also affected by the uneven heating of tanks, glare of the sun, and precipitation.
- overflow which leads to exceeding the permissible load capacity of the tanks, it is necessary to uncouple them, which requires additional expensive shunting.

- the method of controlling the level of loading of railway tanks during the loading of liquid products is characterized by the fact that before starting loading of liquid products, the estimated level of loading (Hi) of the tank is determined based on the estimated temperature (t estimated) of the loaded product, fix the estimated loading level (Hi) of the tank using a loading level control device including a rod with a bar installed at the calculated loading level (Hi), which is placed inside tank for visual inspection of the time at which the level pour-product reaches the calculated load level (H 2) of the tank, the fixed bar, while in the process of filling in using thermal imaging device is carried out measurement of the actual temperature ⁇ YEKU-in) pour-product, while in the case of changing the actual temperature ⁇ 0 teK limiting) of the loaded product from the calculated temperature (t calculated) in the direction of increasing or decreasing, adjust the calculated loading level (N x ) of the tank.
- the testers device is made with a degree of protection IP54.
- the loading control device is placed on the drain valve of the tank.
- the measurement of the actual temperature (1: with y Tek-in) loaded product is carried out through the open neck of the tank.
- the actual temperature (t ° TeKymaH ) of the loaded product is measured by measuring the heating temperature of the wall of the boiler tank.
- the device for monitoring the loading level of railway tanks during liquid product loading includes a rod placed inside the tank with a bar installed at the calculated loading level ( ⁇ ) of the tank, and a thermal imaging device designed to control the temperature of the loaded product.
- a thermal imaging device is placed above the neck of the tank.
- the thermal imaging device is placed in such a way as to provide the ability to measure the temperature of the heating wall of the boiler tank.
