Traditional water level sensors (such as Floaters and Optical sensors, which are floating on the surface of the water) can only measure two points inside the aquarium; the maximum and the minimum of the water level. The eK Level Sensor uses ultrasound to take continuous measurements of the changing levels of tank water. The system is very easy to set up and it also compiles and digitizes the changes in water level over time, so that you can have readily available, accurate data.
The sensor measures precise and continuous water level.
Mount the sensor parallel to the surface of the water.
