Abstract

The invention concerns a device (1) designed to be fixed at the outlet of a tube (2) or pipe delivering a fluid, characterized in that it comprises means for displaying the flow rate and means for displaying the outlet temperature of said fluid.

Claims

1. Device to be inserted at an outlet of a tube or a pipe delivering a fluid, comprising means for displaying a flow rate and means for displaying the outlet temperature of said fluid, said flow rate and temperature display means being constituted by same element, said temperature and flow rate display means comprise a propeller and said propeller being made from a material reacting to variations in temperature.

2. Device according to claim 1, wherein the means for displaying the flow rate and the temperature of the fluid are located in the outlet axis of the fluid.

3. Device according to claim 1, further comprising a substantially cylindrical body adapted to receive the means for displaying the flow rate and the temperature of the fluid.

4. Device according to claim 3, wherein the cylindrical body presents a transparent display window.

5. Device according to claim 4, wherein the cylindrical body is totally transparent.

6. Device according to claim 4, further comprising means for filtration, for treatment of the fluid or reagents to pollutants contained in the fluid.
