For example, they are stored in pails that rise to the top of the tank.

However, when performing measurements using the various conventional measuring instruments as described above, the following problems occur.

That is, for example, a steel tape measure 1, a water test rod 4, and a temperature measurement device 7 each weighing 1.9Kg, 2.6Kg, and 1.5Kg, plus the weight of a pail can of 1.2Kg, which has a total weight of 7.2Kg, is transported to the top of the tank. This requires a great deal of effort.

Furthermore, since measurements are carried out by handling three things: the steel tape measure 1, the water test rod 4, and the temperature measuring instrument 7, there is a drawback that the measurements are laborious and time consuming. Incidentally, it takes 10 to 15 minutes to measure white oil (gasoline, light oil, etc.) and 20 to 30 minutes to measure black oil (A heavy oil, C heavy oil, etc.).

Therefore, in view of the above-mentioned conventional problems, the present invention aims to reduce weight and improve ease of handling by integrating a measuring section, a water testing section, and a temperature measuring section into a single device. The purpose is to

<Means for Solving the Problems> For this reason, the tank tape measure of the present invention is a tank tape measure consisting of a measuring tape and a weight connected to the tip of the measuring tape, in which the weight is Consisting of a water test rod made of a hollow body having weight and a thermometer disposed and supported in the internal space of the water test rod,
