Hi silvarblade,
I just can't imagine a sealed water tank. There has to be at least a vent hole for the air to escape when the tank is filled with water. It shouldn't be a big problem to drill two holes through the lid to extend two thin stainless steel wires into the tank to measure the water level.
You can do the same fitting a dome on top of the tank with a ping pong ball inside a PVC hose which activates a switch if the tank is full to the top. I used that method closing the drainage valve from my garden to the nearby "Khlong" (flood control canal) if the water level in the Khlong is higher than the water level in the garden around the house. To seal the switch from water you can use an ordinary prophylactic or if you can get it use a rubber diaphragm.
