Nuclear power plants - cooling circuits
In a nuclear power plant, water circuits are heated up by nuclear fission of the radioactive material. Most modern reactor types employ primary and secondary cooling circuits, whereas the secondary circuit is used to steam power turbines for electricity generation.
For an efficient, safe operation of such secondary cooling circuits, FLEXIM offers the ideal flow metering solutions.
Conventional flow meter technologies such as orifice plates / differential pressure meters tend to drift due to the abrasive and corrosive medium and technologies such as magnetic inductive devices (MIDs or "Mag-meters") require complete plant shut downs for their installation or replacement.
FLEXIM’s FLUXUS flow meters offer a highly accurate measurement with long-term stability, without the need for invasive pipe installation. Due to matched and paired transducers as well as sophisticated digital signal processing, the measurement system does not drift. Furthermore with no pipe cutting or welding required during installation, process interruption is totally unnecessary and potential leak path risks are minimized.
By making use of FLEXIMs WaveInjector transducer mounting fixture for extreme temperatures, even flow measurements at up to 400 °C / 750 °F hot pipes are possible without any limitations.
Temporary inspection of existing metering systems or currently unmeasured points is also possible with our range of portable flow meters.
FLEXIMs clamp-on flow meters are approved by major nuclear power plant operators. References can be sent upon request.
