11.2.13 Group SENSOR DATA
Function description SENSOR DATA
All sensor data such as the calibration factor, nominal diameter etc. are set at the factory.
"
Caution!
Under normal circumstances these settings may not be changed because changes affect numerous functions of the entire
measuring system, and the accuracy of the measuring system in particular.
Please contact your Hauser service organization if you have any questions on these functions.
K-FACTOR The current calibration factor of the sensor appears on the display.
Display:
e.g. 100 P/l (pulse per liter)
!
Note!
The K-factor is also given on the nameplate, the sensor and the calibration protocol
under “K-fct.”.
K-FACTOR
COMPENSATED The current compensated calibration factor of the sensor appears on the display.
The following are compensated:
• The temperature-dependent expansion of the sensor (see Page 96).
• Diameter jumps in the inlet of the device (see Page 97).
Display:
e.g. 102 P/l (pulse per liter)
NOMINAL DIAMETER The nominal diameter of the sensor appears on the display.
Display:
e.g. DN 25
METER BODY TYPE MB The type of meter body (MB) of the sensor appears on the display (
→
Page 108).
Display:
e.g. 71
!
Note!
• Use this function to specify the nominal diameter and the sensor type.
• The Meter Body Type MB is also given on the parameter printout and the type plate.
TEMPERATURE
COEFFICIENT The temperature effect on the calibration factor appears on the display. Due to changes in
temperature, the meter body expands differently, depending on the material. The
expansion has an effect on the K-factor
