* Stable detection will not be possible in the following cases. Confirm detection capability with the Sensor installed before
actual application.
1. If the specific inductive capacity or the specific electric conductivity of the liquid is too low, the liquid position may not be
detected since this sensor is a capacitive sensor.
2. If the quantity of liquid is too low or the change in quantity is too low in comparison to the change in liquid level because
the pipe is too thin or the walls of the pipe are too thick
3. If there is a viscous film on the inner pipe wall, large quantities of foam or air bubbles, or excessive buildup of dirt on
the inner pipe wall
