I'm not sure I'm posting in the right category or even on the right forum but I need some guidance on building a simple signaling device. I want to make or buy a device that when installed on a piece of rental equipment a person can push a button and it sends a signal back to my office and...

If I have a KF Triation result using Columetric sampling method and my first sample is 59.22 and second is 60.65 and third is 22.03 what does this tell me about the water content of my fuel. The lab I used to use gave me a lamens terms definition.

Does the Caustic solution remain useable for the next tube or will it become less potent. Can I fill the pipe with water to flush the solution up and out into the containment bucket where I would remove it with something? Is there a way to neutralize the chemical?

If I use liquid Nitrogen would I be able to put in in the tube in large quantities? Could I suck it out after a few seconds and put it in the second and third tubes at a site. Since all tanks will be buried the same depth it would take the same amount of liquid to fill each riser. What would...

I am ok with leaving the bottom of the tube floating in the gas. I have rubber plumbers plugs that I can blow up to seal the tube. What I really need to know is how can I recover the Sodium Hydroxide and does the aluminum turn to gas or will I have a pipe full of melted aluminum and Sodium...

Depending on the solution, we could conceivably pre visit the sites with the solution as long as it did not interrupt the normal course of operation for the tank or the site.

Just to mention that removing the riser from the tank is an option but the cost associated with removing a 4'x4' chunk of concrete plus removing and shoring 3' of pea gravel backfill material not to mention permits and such is about 3k and then add the price of the new drop tube $1,500 and the...

These are 10 to 20k tanks at a regular gas station. New EPA mandates that we check the overfill protection on the tanks. The tanks are buried 3 to 4 feet in the ground thus the steel riser. The drop tube is an industry standard part that has been used for 50 years or more. It is basically an...

Any ideas on how I would remove an Aluminum drop tube from a gasoline or diesel tank? The tube goes thru a 4" steel pipe that extends 3' to 4' above the tank. The problem is that after years of being in the tank the aluminum has seized to the steel pipe. I am thinking about trying to melt the...
