Method for installing function monitoring means in a flow machine installation

1. A method for installing temperature monitoring means in a steam turbine installation, wherein the temperature monitoring means are formed by at least one thermochromic coating, the method comprising: selecting at least one component of the steam turbine installation whose temperature is to be monitored; selecting a predetermined thermochromic coating for the component whose temperature is to be monitored; applying the thermochromic coating on the component whose temperature is to be monitored; using the thermochromic paint as thermochromic coating; and applying the thermochromic paint to at least one component of the steam turbine installation, which component is to be monitored with respect to the through-flow of process fluid therein.

2. The method according to claim 1 , wherein the thermochromic paint is applied to at least one pipeline as the component to be monitored with respect to the through-flow of a process fluid therein.

3. The method according to claim 2 , wherein at least one monitoring portion is selected at the pipeline whose through-flow is to be monitored before applying the thermochromic paint, and wherein the thermochromic paint is applied exclusively to the at least one monitoring portion.

4. The method according to claim 3 , wherein at least one monitoring portion is selected which is located directly adjacent to a shut-off device installed in the pipeline.

5. The method according to claim 1 , wherein thermochromic paint is applied to at least one of a steam pipeline and one drainage pipeline of the steam turbine installation.

6. The method according to claim 1 , wherein the at least one thermochromic paint is selected from a group of thermochromic paints which exhibit different colors in different temperature ranges.
