The Model S-4 weigh/fill system is very accurate and easy to operate. The semi-automatic scale has automatic tare, automatic feed and speed controls for both bulk and dribble feed rates, and automatic set points. The product flow from the hopper to the feed pan can also be controlled by an adjustable slide gate. By using a weigh hopper that drops the entire weight at once and an electro magnetic vibrator, the S-4 can be up to twice as fast as other weigh/fill systems, and have greater accuracy at higher speeds and lower net weights.

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.
