This home made water pressure gauge measures the air pressure. It took me a long way to work out how to make one. There is little information on them, I suppose this is because they are so simple. I was sure that there must be more too them. It is just a tube on a board with markings up the side. You put water in the U bend and mark the place that the water falls as "0" You then measure and mark out notches up the side every 1/2 inch. You label them 1,2,3 etc.
To start with I thought that the end of the tube needed to be blocked to get an accurate reading. This was incorrect. More research unveiled that it should be unblocked and the u bend should be slightly deeper. This is taking a pressure reading.
