Abstract

A measuring arrangement for determining a chemical and/or physical, measured variable-especially a volume flow and/or mass flow-of a measured material flowing through a pipeline, wherein the measuring arrangement comprises a measuring transducer, wherein the measuring transducer includes at least one optical waveguide, which serves for producing, registering and/or transmitting measurement signals, and wherein the registering of the measuring signals in the optical waveguide occurs by means of a Fabry-Pérot sensor.
