Model S-4 Automatic Scale System

Model S-4 Automatic Scale System with Floor Stand

The Model S-4 Table Top stand model is built to accommodate situations were floor space might be limited. It's the exact same machine as the Floor Stand model, but shorter! We like to call it the "Perfect Coffee Filling Machine!"

  • Self-adjusting controller

  • Controller range up to 75lbs.
  • Supply Hopper cap. 3.5 cu.ft. (equivalent to 5 five-gallon pails)

  • 120V 60Hz (240V 50Hz option)
  • Handles all dry bulk from powders to large parts
  • Can be used with all bags and rigid containers

  • On-the-fly, self-adjusting bulk & dribble speed control
  • Up to 800 fills/hour


The Model S-4 Semi-Automatic Scale System is a great first step to take your business from hand scooping to automation. Your bulk product is placed in the supply hopper at the top of the machine. The S-4 uses an electromagnetic vibratory feeder to move the product from the supply hopper to the weigh hopper where it is weighed. When the target weight is reached, the Controller stops the feeder, and the weigh hopper opens automatically or with the foot switch to dump your product into your container. A new fill cycle is started and your filled bag may now be sealed.

Example: To run a relatively free-flowing product into a 1lb. package, the product is loaded into the hopper, and the total weight is set at 1lb. After starting the first fill cycle with the foot pedal, the controller will automatically switch into "learn mode" for the first cycle. During this time the controller tests the flow characteristics of the product and decides the best speeds and durations for bulk and dribble. The controller will automatically change the vibratory feed from bulk to dribble and stop the scale at 1lb. The bag is removed and sealed. Each successive container is now filled by placing it under the funnel and depressing the foot pedal.
