Water level meter integrated with a built-in data logger

Features

1. No cables
2. No need to atmospheric relief

• Water level meter integrated with a built-in data logger
• Lightweight and compact with an environmentally robust casing made of stainless steel
• A desired model can be selected from a range of 2 m to 50 m for highly accuracy measurement.
• The built-in battery ensures long-term measurement for approx. three years and can be replaced with a new one (the replacement work to be done by the manufacturer).
• Atmospheric correction is performed after measurement is made with an atmospheric measurement sensor.
• The measurement data can be retrieved easily simply by inserting the meter into the cradle (to be purchased separately).

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.
