Abstract:
1. A method for measuring at least one physical magnitude of cooling fluid flowing in an individual cooling element circuit of a cooling element in a metallurgical furnace having a plurality of cooling elements provided with respective cooling element circuits, the method comprising: feeding cooling fluid to a supply header for distributing cooling fluid and for feeding it to the cooling element circuits of the cooling elements, feeding cooling fluid from the supply header to the cooling element circuits of the cooling elements, selectively conducting cooling fluid from the cooling element circuit of each cooling element to a collection header alternatively either through a survey line or by-passing the survey line, receiving cooling fluid from the cooling element circuits of the cooling elements at the collection header for collecting cooling fluid from the cooling element circuits of the cooling elements, measuring flow of the cooling fluid flowing in the supply header, sequentially conducting cooling fluid from the cooling element circuit of each cooling element in turn to the collection header through the survey line, measuring the flows of cooling fluid flowing in the survey line, summing the measured flows of cooling fluid in the survey line, to provide a total return flow, and calculating a difference between the total return flow and the measured flow of the cooling fluid flowing in the supply header, to provide a flow loss.
