Sensor Data -
Zero Point
AUTO - OOS
Use this function to view the current zero-point correction value for the
sensor.
Zero-point correction is determined and set at the factory.
User interface:
Max. 4-digit number: –1000 to +1000
Factory setting:
Depends on nominal diameter and calibration
Sensor Data -
Nominal Diameter
AUTO - OOS
Use this function to view the nominal diameter of the sensor. The nominal
diameter depends on the size of the sensor and is set at the factory.
User interface:
2 to 2000 mm or 1/12 to 78"
Factory setting:
Depends on the size of the sensor
Sensor Data -
Measuring Period
AUTO - OOS
Use this function to view the measuring period. The duration of the
measuring period is calculated from the rise time of the magnetic field, the
brief recovery time, the integration time and the empty pipe detection
time.
User interface:
Max. 4-digit number: 10 to 1000 ms
Factory setting:
Depends on nominal diameter
!
Note!
The system checks the time entered and sets the measuring period which
is actually used internally to a plausible value. If you enter 0 ms, the
system automatically computes the shortest time.
Simulation -
Measurand
AUTO - OOS
Use this parameter to activate the simulation of the volume flow/mass
flow.
Options:
OFF
VOLUME FLOW
MASS FLOW
Factory setting:
OFF

Caution!
• The measuring device cannot be used for measuring while this
simulation is in progress.
• The simulation acts independently of the position of the jumpers on the
I/O board (
→
see Operating Instructions for Proline Promag 55
FOUNDATION Fieldbus, BA126D).
• The setting is not saved if the power supply fails.
!
Note!
Active simulation is relayed to downstream function blocks or higher-
order process control systems by means of the status UNCERTAIN of the
output value OUT (AI Block).
