CLASS 42: Instruments.

The leakage meter is used to measure the leak tightness of liquids on a fixed Automatically display the scale when the liquid level changes or remains constant.

The sampling, as well as the subsequent spindling of the sample, as it was usual up to now, is avoided.

Two swimmers Sch / and ScIi ₁₁ are combined with one another; they can be made of wood, glass, metal, etc.

While Schwimmer Sehn swims constantly on the surface, Schwimmer Sch /, which is weighed down by the weight ρ , shows the tightness of the liquid by its relatively lower or higher level, like the common spindles.

The level fluctuations are reflected in the same way by the two floats through the toothed racks St / and St _n , through the toothed wheels Z ₁ and Ζ //, and through the shafts W ₁ and W _n supported in the bearings L ₁ L ₁ and L1, L α transferred to the scale S, _n and the pointer S ₁ .

In this case, the scale and the pointer will rotate in the same way, the position of the pointer opposite the scale will therefore remain the same.

The shaft W ₁₁ is a hollow cylinder through which the shaft W _{1 is} passed.

If boiling or for any other reason changes the tightness of the Liquid, this is indicated by the deflection of the pointer on the scale.

The zero point of the scale is for liquids which are specifically heavier than water at the tightness of the latter and to adjust the lowest liquid level; at specific For lighter liquids, this must be done at the highest liquid level.

A round box with a pane of glass k, which is attached to the wall of the vessel, encloses the pointer and scale.

In boiling and flowing liquid, both swimmers are provided with one on the vessel attached guide.

Whether the swimmers are on top of each other, as assumed in the drawing, or next to each other are arranged is the same; the same can be said of the transfer of motion to the scale and done on the pointer in a way other than that by toothed gear and hollow shaft.

Furthermore, with a similar arrangement of the float, the height of the float remains the same Surface of the liquid, the fault will be canceled out by the changing Temperature of the liquid is caused in the leakage measurement.

In this case, both swimmers are weighted and swim under each other the surface; one of the swimmers is within the solution to be examined, the second, however, in a vessel filled with the pure solution liquid, which closes is located within the solution to be investigated. This causes both liquids, the solution and the solution liquid have the same temperature.

Claims (1)

The scale is set in the same way as indicated above, using the im Water or liquid in solution. If the temperature rises or falls, so both the scale and the pointer will move uniformly in the same direction; increases or if the concentration of the solution falls, this is only indicated by the pointer to be brought. Pat τ claim: A density meter for liquids, in which the display device on a Swimmer is built, on whose scale a second swimmer by his higher or lower level indicates the tightness of the liquid. For this purpose ι sheet of drawings.
