I see. I can’t speak to downstreaming. I’m specifically talking about a softwash / 12V diaphragm pump application system here. But yeah, kind of confusing, especially if people refer to it two different ways. I appreciate the advice.
Can you give me your feedback on this tool I just created in Excel? I think it’s pretty cool, and anyone else’s thoughts are more than welcome!
Basically I put in all the formulas needed for a 3 valve softwash metering system. There are 7 variables you can adjust, based on your system or the system you want to try.
- SH concentration % (8, 10, 12.5)
- SH supply line diameter
- Water supply line diameter
- Soap supply line diameter
- SH valve degrees open
- Water valve degrees open
- Soap valve degrees open
It has 2 outputs, SH concentration of the mix (shown as %) and soap in the mix (shown in oz/gal). It’s pretty cool in my opinion. Because of all the variable, the system will pull more or less soap in, depending on how far you open the SH valve, and it all changes depending on what size supply lines you have, and of course what SH strength you are using.
So if someone wanted to calculate their softwash mixing ratios with 10% SH instead of 12.5, they’d just change the value. Or if they wanted to know how much soap you’ll pull in to your mix if you have a 4% SH strength, you can add in the numbers and get your answer. You can see how far to open each valve to get the desired mix.
I want to take this a bit further and have it reverse calculate, meaning you type in the desired outcome and it tells you how far to open each valve to achieve that SH strength and soap content. That’s a bit more difficult though lol.
