eK Level Sensor
This sensor continuously and precisely measures water level without touching the water. Traditional water level sensors (e.g. floaters and optical sensors, which float on the surface of the water) can only measure two points: the maximum and the minimum points of the water within the aquarium. The eK Level Sensor uses ultrasound waves to take continuous measurements of the changing levels of tank water. The system requires minimal setup, and compiles and digitizes the changes in water level over time, so that you always have accurate, readily available data.
No need for constant adjustment
No unwanted algae
Instantaneous water level reading
Mount the sensor parallel to the surface of the water. The sensor will continuously and precisely measure the water level within your aquarium.
