Radar Tank Gauge Caution During the learning period fast filling emptying or turbulent surfaces can result in switching off and on the phase evaluation Subsequently observed measurement errors will disappear as soon as tank levels come back to areas measured by 7500 RTG previously with activated phase evaluation If the observed measurement errors are corrected by dip table entries the 7500 RTG will take care of these corrections and automatically adjust the index correction table Do NOT correct any settings in the basic calibration or the extended calibration Note Immediately after installation the 7500 RTG measures with the specified mm accuracy Until the level range has been completely covered by the medium setting up the correction table the maximum permissible filling speed is 100 mm level change min After this the fill speed has no limitation 6 3 Function pipe diam corr 032 only relevant for 7532 RTG 40 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 7500 RTG also has an automatic pipe inner diameter correction This adjusts the entered
