Product Solutions for Power Industry


Electric power is a fundamental necessity in all municipal and industrial endeavors. Power companies are relying more heavily on automation and control technologies to increase productivity, reduce costs and improve their safety standards. By remote monitoring and control technologies companies are able to prevent hazardous situations and improve their health and safety standards.


Automation and control systems are used throughout the industry gas turbine based power generation systems, to production and processing plants, and distribution and retailing of petroleum products, helping to raise efficiency, speed and performance of companies’ operations. With the aid of control, automation and monitoring technologies companies can monitor and report their activities with greater transparency and therefore improve processes and safety.

Application and Measurement Principle:

Boiler feed water is water used to supply (feed) a boiler to generate steam or hot water. The feed water must be specially treated to avoid problems in the boiler and downstream systems. Untreated boiler feed water can cause corrosion and fouling. Corrosive compounds, especially oxygen, must be removed by deaeration systems. OXYTRANS allows to measure and control O2 concentration with highest precision. Centec deaeration skids based on membrane and column technology are generally equipped with OXYTRANS for highly efficient process control.

An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O2 is present the energy is transferred from the indicator molecules to the oxygen. By detecting the red light, OXYTRANS determines the O2 content with highest precision.




Application and Measurement Principle:

In nuclear power plants the heat generated by a nuclear fission process is used to drive a steam turbine which generates usable electricity. When an atom of nuclear fuel (uranium) absorbs a neutron the uranium will fission into two smaller atoms (waste) and release 1 to 3 neutrons. The kinetic energy of the waste is used to heat the water for the steam turbine. The neutrons are used to fission the next lot of uranium atoms, so the process continues. Boric acid (H3BO3) is dissolved in the reactor coolant where it absorbs the neutrons and thus controls the speed of the nuclear fission process. The concentration of H3BO3 is determined with highest precision based on density measurement.

For density measurement, the liquid consisting of 2 components flows through a U-shaped tube. While the tube is electronically excited to oscillate at resonance, the oscillation frequency is observed. Any change in the fluid density has an impact on the detected signal and can thus be identified. Based on the correlation between concentration and density, the concentration is calculated and displayed.
