maximum permissible filling speed is 100 mm level
change / min. After this, the fill speed has no limitation.
Function"pipe diam. corr." (032) (only relevant for FMR532)
For level measurement in stilling wells, radar systems require highly precise pipe inner diameter
data. An mm-exact level measurement cannot be guaranteed for deviations from the actual stilling
well inner diameter of more than ± 0.1mm to the value entered in the function group "
basic setup "
(00) . The errors which occur as a result are linear and can be corrected with a dip table containing
at least two entries. The Micropilot S also has an automatic pipe inner diameter correction. This
adjusts the entered stilling well inner diameter (input in the function group "
basic setup " (00) ) to
the actual values. However, this presupposes that the value entered in the function group
"
basic setup " (00) matches the actual pipe inner diameter accurately as possible. The user-defined
value entered in the function group " basic setup " (00) can be corrected with this value. Then,
switch on the " pipe diam. corr. " (032) function, after a level change of at least 5 m has occured
since start-up. The pipe diameter, which the instrument determines automatically, will then be
transmitted to the "
pipe diameter " (007) function..
!
Note!
Only if the "
pipe diameter " (007) function has changed its value, it is necessary to perform a
" history reset " (009) and to delete the dip table after activation of the " pipe diam. corr. " (032)
function. Otherwise the level change of 5 m has not yet been exceeded. The " pipe diam. corr. "
(032) function must be deactivated again and the procedure should be repeated at a later point of
time.
