Does anyone have what I refer to as a "mix-n-fill" tank in their shop? I will try to explain what I am talking about in case you refer to this as something different. We currently fill the tanks on our trucks with water, and then in a separate instance we will pump liquid fertilizer into those tanks. This has to be done each time the truck is empty. I would like to have say possibly a 1000 gallon (or larger depending on recommendations from you) that we could have in the shop that would allow us to mix the water and chemicals needed. Then we would be able to pump directly from here into the truck all at the same time. I know that there will need to be some form of an aggitation pump in the tank to keep the wwater and chemicals from separating. Do you have pictures of what you do? Do you know what type of pump would work for this scenario? Also, do you know where I can find a gauge that can go onto a pump hose to calculate the gallons of flow through the hose and into the pump? I know t hey have them for fuel tanks, but I have been told that the chemicals will corrode these particular gauges. Do they make them specifically for chemicals? Thanks in advance for your assistance!
