Usage: When measuring, insert the ruler body of the special ruler for star counting of the tank car into the cap of the tank car,
gently place the beam on the measuring position designated by the cap, let the ruler body immerse in the liquid, and then use
the ruler body for measuring the tank car. Lift the ruler and read the scale value of the liquid trace displayed on the ruler
surface. This value is the distance between the width of the tank car and the page inside the tank car, that is, the space height.
Precautions:
1. Measure the tank car after the liquid level is stable.
2. The beam of the special ruler for tank car measurement is placed on the cap mouth, and once it contacts with the cap mouth,
it can be read.
3. Don't wipe the used special ruler for tank car measurement at the upper end of the tank car cap.
4. Don't wipe the special ruler for tank car measurement with chemical fiber and items that are easy to generate static electricity
to prevent static electricity.
