Improve the safety of your steel production with our dedicated measurement and software offering
High temperatures, molten metal and heavy loads – steel production puts a lot of stress on both man and machine. So it is only natural that safety and availability are one of the top priorities for steel plant managers. Not only to prevent potentially deadly accidents from happen but also to make sure that production in an extremely competitive landscape never stops. For that you need robust measurement equipment that provides reliable data as well as smart control solutions.
Comply with functional safety standards IEC/EN 61508 (process hazard categorisation known as SIL – Safety Integrity Level) and IEC/EN 61511 (process safety using instrumentation known as Safety Instrumented Systems) in accordance with EN 13849 with process experts who guide you every step of the way in selecting the best-fit, industry-optimised instrumentation, service and solution package from our complete portfolio based on more than 60 years of experience.

Safe, robust and precise water leakage monitoring
Malfunctions in water circuits can be very dangerous to both equipment and personnel. Regardless of the cooling circuit type, principles for leaking detection are as follows: the inlet and outlet flow rates of a cooling circuit are measured by means of suitable flow meters, either electromagnetic or ultrasonic. The inlet and outlet temperatures are also acquired from sensors mounted in close proximity to the flow meters. Our system uses separate temperature sensors to achieve maximum accuracy

Electromagnetic flow meters are typically in use for the circuit flow rate measurement. Their physical principle is based on Faraday’s law of induction where a voltage is induced in a conductor moving in a magnetic field. In electromagnetic measurement, the flowing medium corresponds to the moving conductor. The induced voltage is proportional to the flow velocity and is detected by two measuring electrodes and transmitted to the amplifier. Flow volume is computed on the basis of the pipe’s diameter. A constant magnetic field is required for accurate measurement. This principle of measurement is important not to install the flow meter so close to the Electric Arc Furnace’s electrical field. The flow meter can with stand in an external electric field of 90 Gauss (9.10³ tesla). The flow meters are developed to show more process values than ever. All of them are available on a digital network.
Assignable measured Variables on the current and frequency outputs: Volume flow, Mass flow, Corrected volume flow, Flow velocity, Conductivity, Corrected conductivity, Electronic temperature, Temperature,
In a furnace leakage detection application we can see added value in using temperature measurements to support the control. This can serve as an additional temperature in-line to confirm if the independent temperatures are correct, temperature is a critical measurement in this application. In addition, conductivity can be a water quality measurement that can be related to concentration and possible scaling in the line. If your lines became restricted because of blocking/calcification the cooling system will not work optimally and can cause serious plant shut downs and production loss.
To help you verify if anything goes wrong in-line, you can use the Proline’s Heartbeat Technology.
