Liquid Filler ControllerThis automatic liquid filler machine uses pneumatic system operation to measure liquids like paint. It uses BASIC Stamp to control a Load Cell based digital weigh scale indicator with 2 set points.

When the user places a container on the weigh-pan, a valve opens and product begins to flow. When the container has reached its target weight, the valve closes. In order to decrease the error of product remaining in-flight, sampling speed is fast (about 38 reading /sec).

Features: 5 digit display 00.000 Kg, 16 buttons keypad, AC load cell excitation, Zero calibration (performed after power up or manually using the keypad).
