Hopper Scales

Hopper scales manufactured by SME Tomsk Electronic Company are aimed for static weighing of bulk and liquid materials within process lines. Hopper scales are registered in the State Register of Measuring Tools and allowed for use in the Russian Federation and Republic of Kazakhstan.

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.
