Cerabar S/Deltabar S Level measurement (FF configuration program)
Endress+Hauser 9
!
Note!
1. For this level type, the measured variables %, level, volume and mass are available. → See
Page 40 ff.
2. You can also specify customer-specific units. See parameter descriptions for CAL_UNIT
(→ Page 34), HEIGHT_UNIT (→ Page 41), VOLUME_UNIT (→ Page 42) and MASS_UNIT
(→ Page 43).
3. The "Wet" calibration mode (LEVEL_ADJUST_MODE) is not available by means of the
FF operating programs. A kind of wet calibration can be carried out as follows:
– Select the "No linearization" option by means of the LINEARIZATION parameter.
– Select the "Level", "Volume" or "Mass" option, depending on the measured variable required,
by means of the PRIMARY_VALUE_TYPE parameter.
– Fill the tank up to the lower level point.
– The PRESSURE_1_AFTER_SENSOR/SENSOR PRESSURE parameter displays the pressure
present at the device. Enter the value displayed for the SCALE_IN parameter, EU_0
element.
– Enter the associated level value for the SCALE_OUT parameter, EU_0 element.
– Using the SCALE_OUT parameter, "Units Index" element, select a unit to suit the measured
variable.
– Fill the tank up to the upper level point.
– The PRESSURE_1_AFTER_SENSOR/SENSOR PRESSURE parameter displays the pressure
present at the device. Enter the value displayed for the SCALE_IN parameter, EU_100
element.
– Enter the associated level value for the SCALE_OUT parameter, EU_100 element.
12 Enter the tank height via the LEVEL_TANK_HEIGHT/
TANK HEIGHT parameter, here 4 m for example.
13 Enter the level offset via the LEVEL_OFFSET/ZERO
POSITION parameter, here 0.5 m for example.
14 Set the Pressure Transducer Block to the "Auto" block
mode.
15 If necessary, use the Analog Input Block to configure the
CHANNEL parameter (→ Page 67), L_TYPE parameter
(→ Page 69), XD_SCALE parameter (→ Page 73) and
OUT_SCALE parameter (→ Page 71).
16 Result:
The measuring device is ready for level measurement.
