System example
The water level meter for water level change measurement (WLG series) is immersed in water, and the atmospheric pressure meter for atmospheric pressure change measurement (WLG-OOM) is installed on the ground.
After the measurement, insert the water level meter into the cradle connected to the PC and load the data to the PC. Accurate water level data is calculated by subtracting the changes in the atmospheric pressure.
