One of two methods can be selected for this. Rel. threshold The measured value is equivalent to the point where the intensity of the echo reaches the adjusted relative threshold.
- Page 21 IFL 70x IQ Commissioning Setting Selection/values Explanation With this setting, the echo to be evaluated Echo selection is determined. The echo is automatically identified according to the criterion that was set. Topmost echo The topmost echo (from the surface of the water) is used for calculating the mea- sured value.
