It took me a while to discover this thread, most of the co2 system build threads were in the equipment section.
Well, I got my regulator assembly stand built today. I used 3/4" acrylic for the base and 1/2" acrylic for the supports. I flat sanded all the edges with a very slight roundover and flame polished it. I am really pleased with how it came out.
Now I need to work on the electrical. Hoping to make the wiring discreet enough that it is not an eyesore. I will probably use Cat5 cable between the solenoids and the plug socket that will be tucked under the primary regulator.
I will be putting dosing reservoirs inside the cabinet so I will have enough room for any combination of dosing pumps and ph controllers for up to 4 tanks. I know I will have two sets here. Will probably have the other ones at their respective tank locations as they are farther away.
Sorry about the low quality pics, I am running low on photo space.
nice build, good looking multiple output system.
flow meter as measuring device, your option is limited. Instead of dywer, try brooks instrument sho-rate flow meter, you are looking for the one with a number on the flow adjust valve cap, best number is "1", any number bigger than 3 or mark "M" "H", or "L" are not the one you need, so the only options are "1", "2", or "3".
Trying to go next level. Just my style right? I have become obsessed with electronic flow controllers like the sierra side track mass flow controller. These are available in 0-100 and 0-200 cc/min options. Looking for some feedback on what I have found. @jeffkrol
I am looking forward to hearing from you in particular, because you have a great grasp of technical details. This is the link to the Sierra side track flow controller instruction manual.
I did a quick read-over of the connections and it seems to me that a simple potentiometer is required to adjust settings as illustrated on page 2-7 and 2-11, and a +15v, -15v and a common ground are the power requirements. a flow meter could easily be used to confirm the output flow and I could adjust the potentiometer accordingly.
Am I missing something here? Could it be that simple?
you don't need a mass flow controller to control the flow rate, because I think you still need a digital input unit to connect to the controller, and when you start looking for a digital input/control unit, I think you will back off from the idea....
But you are correct we can use a mass flow controller as a bubble counter(metering device), some controller are metering only, with digital display build in. I own two of them since 2012, bought them around $50 each, new, one aalborg 0-50 sccm, another is omega, I think it is 0-200 sccm. I tried them in 2014, both work really good but not for CO2, so the flow rate is a reference but does not represent the exact figure.
I need to update my metering valve selection thread, had all the info ready about more suitable metering valves and solenoids, but failed to do so in 2014 before I took a long break from PT.
