So here what my boss want me to do.
I got 2 Mixers (A, B)
These mixers can do 3 types of liquid (L1, L2, L3)
When the mix is done I need to pump the mixer (A or B) to one of these Storage Tanks (ST1, ST2, ST3 or ST4).
Here is the thing, in the best world I would have line and 3 flowmeters for each product (L1, L2, L3).
But my boss wants to use 1 pipe, 1 pump and 1 flowmeter for the 3 liquid.
Every time we use a new one we need to push all the liquid out with air or something to empty the more we can.
After this we going to clean the pipe with hot water.
Flush the pipe with air again.
And from there we would be ready for a new batch.
For the piping I would have 2 options: Going up with a 2" NPT pipe like 45 feet in the air or going straight for around 75 feet and coming down to the storage.
The other option I could see is to dig up the floor and put the pipe in the floor so basically from the pump it would go 2 feet down, then 75 feet straight and going 2 feet up to the storage tank.
That's prety much what my boss wants. I'm trying to work his idea, but a big problem I can see at the moment would be to push the liquid with air for cleaning or the batching liquid. If the pipe was on the floor I guess it could work, but 42 feet in the air? No way.
Also the pressure and everything to air blow the liquid I don't know much but I'm pretty sure it's not legal to use 100 psi like he would like to. I would need more info about this.
For the flowmeter I was thinking about a mass flowmeter because all the liquid will have a different mass.
So that's pretty much what I'm working on at the moment. If you have any suggestions or ideas for this application, let me know! Thanks.
