Hopper scales are aimed for weighing of bulk and liquid materials combined with control systems KV-03 or SD-03 and used for charge feeding lines in order to meter materials and setup continuous batchers. Hopper scales are automatically calibrated by a load cell.

|
Configuration of hopper scales is highly reliable - only quality components and the most advanced control system are used for them.
