Are you saying temperature makes the level itself move around on the tape, or it actually changes the level reading?
Just curious as I had a stick on above the cabinet near the landing gear switch that worked great for years until I sold the unit. I also had the large bubble level on the front pin box that could be read from the mirror. Loved that one, as it gave me immediate notice if the site was level left to right or if I had to drag out the pads to put under the tires.
Temperature does have an effect on bubble levels.
Years and years back when I was first starting out in construction I had set up a transit to shoot elevations for a foundation pour. There was a surveyor on the job site and when I was breaking for lunch he told me to put the cover on the transit. I asked him why and he came over and told me that as the sun moved across the sky and hit the transit it would change the bubble.
He then took his finger and held it just above the glass and to one side of the line and darned if the bubble didn't start to move towards his finger. He told me this was because of the heat from his finger. When he took his finger away the bubble went back to its original position.
