Average The measuring range filter is used for the adjustment to
slower working devices or for a continuous output of the
analog output.
Menu point 2.3 for velocity and
Menu point 2.4 for density.
Storage Adjusted values are confirmed by pressing the ENTER-
button. Leaving the menu level by pressing the ESC-
button. All changes are automatically stored and the new
values are set as standard.
Suggestion for the Calibration Procedure:
Step 1 Input of the requested throughput value of the final value of the measuring range
in menu point 2.2
e.g.: 20mA = 20000 Kg/h
Step 2 Input of the requested density value of the final value of the measuring range in
menu point 2.1
e.g.: 20mA = 800 Kg/m³
Step 3 Alignment of the minimum density value with empty pipe.
min = 0 kg/m³ in menu point 3.5
Step 4 Alignment of the maximum density value by complete filled pipe (e.g. 800 kg/m³)
in menu point 3.6
Step 5 Input the diameter of the pipe in menu point 2.5
Step 6 Conveying of the product on maximum throughput rate over a constant time
interval (e.g. 10 min.). During this time period the throughput must not change.
Step 7 Measurement of the throughput quantity by weighing.
Step 8 Calculation of the correction factor by differentiation
Value measured
Correction factor = -------------------------
Value weighted
Step 9 Correction of the measured value by entering the correction factor in menu
point 2.6
