SU91823A1 - Weighing fluid gauge - Google Patents

Description

In the known dispensers for liquid fuels, the metering is usually done in volumetric units, which does not ensure the determination of the exact weight quantity of the dispensed liquid fuels, which are known to have different specific gravities, depending on the fractional composition and temperature.

A feature of the proposed column is in its calibration device, which provides automatic change in the volume of liquid fuel in a measuring vessel, depending on the density of the fuel, and allows measuring the weight quantities of liquid fuel.

The device is made in the form of a float immersed in liquid fuel filling the constant volume chamber. The float is suspended at one end of the two shoulders; at the other end of this lever, a calibration ring is fixed at a certain height relative to the upper end of the discharge pipe, thus achieving a change in the volume of fuel filling the measuring vessel, depending on the degree of float immersion. Another embodiment of the proposed fluid gauge is associated with the use of a full immersion hydrometer as a float associated with a flexible filament with a calibration ring.

Figures 1 and 2 depict two forms of the proposed fluid-step.

This fluid meter is made in the form of two measuring vessels 1 and 2 interconnected with each other (Fig. 1) with drain pipes 3, the height of which is designed for the liquid with the smallest specific gravity and, therefore, for the largest volume of liquid supplied corresponding to the given weight. Between the measuring vessels / and 2 there is a chamber of a fixed volume, provided with a drain tube 4, inside which there is a float 6, illuminated to the inner ends of the double-arm levers 7; rings 8 are suspended to the outer ends of the latter; displacing liquid from the measuring vessels / and 2 in an amount corresponding to

Works as a liquid (;. Oshem.er as follows.

Liquid through a pipeline or by gravity through a pipeline enters simultaneously into one of the measuring vessels (/ or 2) and into the chamber 5 of a constant volume filled with liquid up to a certain level.

At the same time, the float occupies a certain position, depending on the specific gravity of the fluid, and by means of levers 7 sets the ring 8 to a certain position. The levers 7 are balanced by means of weights 12 and adjusting nuts IS.

Another embodiment of the liquid gauge differs from that described in that ring M (see Fig. 2), which displaces the liquid, is connected by means of a flexible thread J6 thrown over the roller 15 with a full immersion hydrometer 17.

The latter, depending on the specific gravity of the liquid, will accordingly rise or fall, and its movement will cause corresponding changes in the position of the ring 14, which will displace the excess amount of liquid through the drain pipe 18.
