SU29995A1 - Liquid Anemometer - Google Patents

Description

This invention relates to aerodynamic liquid anemometers with a manometric tube. In the proposed liquid anemometer, in order to mark the highest rise in the level of the liquid in the manometer tube, the internal cavity of the last CGG is 5, changing its color when wetted with the liquid contained in the α-tube of the anemometer.

The drawing shows a vertical section of the manometric part of the anemometer.

The proposed liquid anemometer consists of head and gauge parts. The head section is a conventional pitot tube, fitted with a vane, rotating around a vertical axis and mounted in the direction of the wind. The manometric part consists of a vessel A with a hermetically sealed graduated glass tube screwed into it-B.

Dynamic pressure is transferred to vessel A through port C; the static pressure is transmitted to the graduated tube B through its upper end. The inner surface of the tube is covered with a thin layer of a substance that stains in contact with the liquid poured into the vessel A. Depending on the wind speed, the fluid in the tube rises more or less high and its maximum lift will be represented by the length of the colored part of the tube.

The subject matter of the invention.

Aerodynamic liquid anemometer of the type with a manometric tube, characterized in that, in order to mark the highest level rise of the liquid in the manometric tube B, the surface of the inner cavity of the latter is covered with a layer of substance that changes its color when it is wetted with I and contained in the tube I of the anemometer.
