Liquid Filler Machine
Liquid Filler Machine by Mohamed Refky
Mohamed Refky used the BASIC Stamp® 2 module to control a Load Cell based digital weigh scale indicator with 2 setpoints. This indicator is used in filling-by-weight applications. This liquid filler machine uses pneumatic system operation to measure liquids like paint.
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).
Brief specifications:
- 5 digit display 00.000 Kg
- 16 buttons keypad
- AC load cell excitation
- Zero calibration is performed after power up or manually using the keypad.
