P25: - - - a Selection of Echo within the measuring window FACTORY DEFAULT: 0
The measuring window is formed around the echo signal. The position of this measuring window determines the flight time for calculating of the
distance to the target (the picture below can be seen on the test oscilloscope).
a Echo in the window to be selected Note
0 With the longest amplitude Most frequently used
1 First one For liquids with multiple echoes within the measuring window
Some applications involve multiple ( interfering) echoes even within the measuring window. This parameter influences selecting the
echoonly within the measuring window.
EView2 setting: “Device Settings” → “Measurement optimalization” → “Selection of Echo within the measuring window.”
P26: - - - - Level elevation rate (filling speed) (m/h or ft/h)) FACTORY DEFAULT: 2000 m/h
EView2 setting: “Device Settings” → “Measurement optimalization” → “Level elevation rate (filling speed).”
P27: - - - - Level descent rate (emptying speed) (m/h or ft/h) FACTORY DEFAULT: 2000 m/h
These parameters provide additional protection against echo loss in applications involving very heavy fuming. Setting the correct value increases
the reliability of the measurement during filling and emptying.
The unit of the value is [m/h] if the metric unit system is selected and the parameters must not be slower than the fastest possible filling/emptying
rate of the employed technology.
EView2 setting: “Device Settings” → “Measurement optimalization” → “Level descent rate (emptying speed).”
Caution! In tanks with conical or pyramidal bottoms, the level change rate at the bottom of the tank increases significantly!
