8.6.11 Auto tank height
FCT. 3.5.1 AUTO TANKH.
With this function the height of the tank can be determined
by the BM 70 A/P itself, provided the following conditions
are met:
•
The tank has been completely drained for at least 2
minutes.
•
The tank bottom has good reflectivity (not suitable for
dished and tapered bottoms without reference plate).
•
The functions Fct. 3.1.3
(extension), Fct. 3.1.5 (distance piece) and Fct. 3.1.6
(stilling well) must previously have been correctly set.
•
If the tank is taller than 30 m, the approximate tank
height must previously be set manually with Fct. 3.1.1,
as otherwise the measuring range will not suffice to
locate the bottom.
After pressing the → key the display shows the currently
measured value for the tank height. Press key
inquiry "SURE NO" now appears. If you are not sure
whether the measured value coincides with the true tank
height, reject the value by pressing key
If the measured value seems plausible for the tank height
and you wish to store it, change the option to "SURE YES"
by pressing key ↑, and then press key
