Often times we fill smaller containers from tote tanks using a ball valve connected to a nozzle and using a weight scale with a person operating the release and shut off of the valve. Is there a better way to do this? Perhaps a combination of weight/load sensors (to make sure container is filled to the desired amount) wired to a solenoid valve (to shut off valve). Just a thought experiment not sure how one would go about automating this?
Just wanted to show the valve and nozzle setup. The liquid for my actual application was Isopropyl Alcohol which has a density of 0.79 and specific gravity 785 kg/m³. It is also flammable so something that doesn’t need electricity to actuate would be ideal.
