Radar-sensored limnigraphs are used to measure water levels in rivers, dams, lakes, irrigation canals, flood control, wastewater management, coastal design and environmental studies. The WLR-01 automatically records the water level in the desired recording range and can transfer data from the RS-232 port of Limnigraf to modems. USB port is used for data transfer to the laptop computers. The data logger can display excel and text files via computer program. This data can be viewed graphically through the program.
Ideal sensors for all applications in "flow" and "volume" measurement depending on "level" or level in water and wastewater treatment plants. Due to its compact design, it has shown the highest level of accuracy in contactless level measurements, especially in rivers, canals, dams and lakes.
The data logger's LCD instantly displays water level, date and battery values. Parameter values can be changed via the keypad, offset values and sensor gain can be adjusted. When the display is active, the first page shows the water level value of the first channel.
