Abstract
The measuring tube of the in-line measuring device is lined internally with a liner. The liner is made of a polyurethane produced using a catalyst that contains metal-organic compounds. The metals that are brought into the liner and remain there are chemically, especially atomically, bonded to carbon chains formed in the liner. The in-line measuring device is thus especially suited for measuring drinking water.
