Gammapilot FMG50 Commissioning
Endress+Hauser 63
The value for the empty pulse rate of the measuring point is calculated in the Endress
+Hauser Applicator
4)
and entered here. With this patented process, the Gammapilot
FMG50 can calculate an absorption coefficient on the basis of the specific geometry of the
measuring point and therefore calibrate the density measurement.
Calibration density point 1:
1. The radiation is switched on and the beam path is filled with medium of a known
density. The calibration point should be as close as possible to the operating point of
the density measurement.
A0042212
The calibration can be performed by pressing the "Start calibration point 1"
button. The measurement then starts automatically and continues, at the very
maximum, for as long as has been configured for the calibration time. However,
the process can also be stopped manually by pressing the "Stop calibration"
button.
The calibration stops automatically as soon as a million pulses have been
totalized.
Alternatively, the pulse rate can also be entered directly.
For the "Next" button in the Wizard to be enabled, the value must, however, be
changed from the start value, at least temporarily.
2. With this calibration point, the density of the medium is entered in the "Density value
of calibration point" field.
This establishes the reference between the determined pulse rate and the density
of the product.
TIP: it is recommended to take a sample of the medium during the integration
and determine its density subsequently (e.g. in the laboratory).
TIP: it is not necessary to activate the density point as the density point is
activated automatically if only one point exists.
CAUTION: in the "Density" operating mode, it is essential to assign the lower limit
value (4 mA) and the upper limit value (20 mA) of the current output to the
density.
