The problem of accurate loading of vehicles (railway cars, trucks, barges, etc.) has always been actual. Overloading a vehicle entails wear and tear and also shortens its service life. Underload increases the cost of transporting a unit of cargo. Significant are also fines, which are imposed by the regulatory authorities on the participants of transportation in connection with violation of the norms for loading vehicles.

For 20 years, the firm "Sweda, LTD" has been developing, serially producing and widely selling the hopper scales SWEDA VBA, which are used both in various technological processes and when loading bulk and liquid products into vehicles.
