With a production average of 90 tons/hours, the facilities in Calarasi production data:

• electric furnace - transformer power 100 MVA
• ladle furnace - transformer 50 Mw/nominal capacity 100 tons / 90 tons liquid steel per heat
• continuous casting machine - round bars Ø 148 - 260 mm; rectangular blooms 350x260 mm
• production average - capacity 90 tons/hour

Solution
Dozens of trucks enter and exit the facility in Calarasi every day. The client needed to have an accurate database about what vehicles enter, what are carrying, what is their weight.
The client wanted a solution to automatically collect number plates pf trucks on the wighh system to the internal ERP (SAP) eliminating the possibility of fraud and for an exact inventory.
Two heavy weight industrial weighing machines were installed at the location. One for the entrance, the other for the exit. Each truck entering the production plant is weighed to determine the quantity of metallic waste to be melted and transformed in pipes.
Each of the weighing machines has 2 LPR cameras Mobotix M24-LPF. One of the camera will record the license plate for the trailer and the other will record the number plate of the tractor head, as it is known they can have different license plates.
Metrici LPR offered also low-pass filters for the cameras for a better IR detection. All 4 cameras were connected at a Metrici Towersys 110 server.
