Description
Volumes added up at current (temperature and pressure) conditions.
Z26: If the characteristic correction is deactivated, A05 is not visible
and cannot be adjusted.
If a characteristic correction is activated, this characteristic curve
correction is deactivated from 0 up to this value A05.
Starts and stops a volume flow measurement
Sets the volume flow rate to 0
With the meter factor (pulse value), the corresponding operating
value flow is calculated from the signal frequency of the sensor ele-
ment in the meter electronics.
The meter factor must be calibrated at the factory so that a direct
meter display in cubic meters.
Note
A change of this adjustment takes place in the responsibil-
ity of the operator.
After any change to the meter factor, calculation takes place
with the new value immediately.
The uninfluenced signal frequency of the sensor element is available
at the HF output. The frequency range can be determined from the
meter factor K and the minimum and maximum operating volume
flow of the meter according to the formula:
