I have trucks that unload fluid into our system at some pressure and I would like to take samples throughout the unload process to characterize that load. Trucks often unload one after another without an operator present to change sample bottles. The fluid varies in type, and sometimes there will be lots of solids and gels in it which can plug small orifices. We charge on contaminants though so it's important we get these in our sample.

Does anyone know of a cost effective, off-the-shelf solution, or components, that is available that basically opens and closes a 1" valve at programmed intervals while a pressure switch is on, filling a bottle roughly the size of a pop bottle, and then once the pressure switch is off, move the bottle down the line so the next bottle can be filled? I'm thinking I would need room for about 20 bottles a day per unloading area and then have the operator reset it daily. Moving the bottle down the line is a luxury though, and I would weight that against the cost of having an operator change out bottles.

Another luxury I would also like to know if it exists, is a system that could label these bottles based on some very simple hmi data input.

If anyone knows of such an off-the shelf system, or knows what components could be put together to form this system I would greatly appreciate a point in the right direction!

Thanks,
Chad
