Monitoring critical cooling water and auxiliary circuits

Safe cooling water leakage monitoring and optimized electric steel making process

Inside a typical EAF (Electric Arc Furnace) there are water cooling circuits for the panels and walls, which have been installed to control process heat and to avoid thermal damage or destruction of equipment. These water circuits are critical points as a malfunction can alter not only the process but influence the furnace itself. In some cases, personnel may even be endangered. Control of the cooling circuit is both an operating and safety issue.

Safety leakage detection solution (LDS) according to IEC/EN 61511 (SIL Safety integrity level) and EN ISO 13849-1.

For more information go to " safety leakage detection".

Make your auxiliary circuits cost efficient

Monitoring and controlling the auxiliary circuits ensure electric steel making processes are reliable and result in production cost savings. Beside the electrical energy, natural gas, oxygen and slag-forming, additional parameters have to be measured.

Preferred instrumentation for auxiliary circuits

  • Robust and ultra-compact Coriolis devices Promass E or Vortex meter Prowirl for oxygen

  • TR15 temperature sensor and Cerabar PMP51 pressure transmitter

  • Direct mass flow measurement of gases with thermal flow meter t-mass 65F as flange version

  • Flow indicator for bulk solids Solimotion FTR20, where changes in the mass flow can be signaled by the 4…20 mA current output

Benefits of your measuring point

  • One competent supplier for initial measurement design, project design with supporting
    technical documentation, delivery and installation of the equipment

  • One supplier for all measurement points such as temperature, pressure and flow

  • Services and tools encompassing web asset management
