Deltabar M 4...20 mA HART Commissioning
Endress+Hauser 35
Description
8 a. The hydrostatic pressure for the lower calibration
point is present at the device, here "0 mbar" for
example.
b. Select the "Empty calib." parameter.
c. Enter the volume value, here "0 l" for example.
Menu path: Setup → Extended setup → Level →
Empty calib.
P01-FMX21xxx-05-xx-xx-xx-029
P01-FMX21xxx-05-xx-xx-xx-030
Calibration with reference pressure (wet calibration)
1 See table, Step 10 .
2 See table, Step 8.
3 See table, Step 9.
9 a. The hydrostatic pressure for the upper calibration
point is present at the device, here "400 mbar" (6
psi) for example.
b. Select the "Full calib." parameter.
c. Enter the volume value, here "1000 l" (264 US
gal) for example.
Menu path: Setup → Extended setup → Level →
Full calib.
10 Enter the density of the medium, using the "Adjust
density" parameter, here 1 g/cm
3
(1 SGU) for example.
Menu path: Setup → Extended setup → Level →
Adjust density
11 If the process uses a medium other than the medium on
which the calibration was based, the new density must
be specified in the "Process density" parameter.
Menu path: Setup → Extended Setup → Level →
Density process
12 Result:
The measuring range is set for 0 to 1000 l (264 US gal).
0 l corresponds to an output current of 4 mA.
1000 l (264 US gal) corresponds to an output current of
20 mA.
