Operation
In the status register all messages since the last manual clearing are
collected. Here, you can also see what has happened, for example, since
the last station inspection. The messages can be cleared at the device
(Serv. -> Status -> Clr).
Only alarms and warnings ( chapter 8.2) are displayed in status registers.
VbMP – Maximum measurement period counter Vb in the
6.4.3.4
current month
The maximum time stamp is displayed in the following line after moving the
cursor to the value "VbMP".
The maximum values from the past 15 months can be requested in the
monthly archive 1 (see chapter 6.4.4 "Admin" register (Administrator).
VbDy – Maximum measurement period counter Vb at the
6.4.3.5
current day
The time stamp for the maximum value is displayed in the following line
when moving the cursor
e value "VbDy".
The maximum values from the past 15 months can be requested in the
monthly archive 1 (see chapter 6.4.4 "Admin" register (Administrator).
Qb – Flow at base conditions
6.4.3.6
Current flow at base conditions (standard flow rate)
Qb = Qm C
with
The maximum inaccuracy of the displayed value roughly corresponds to
the maximum inaccuracy of the Qm.
For the alarm, the Qb is calculated with the replacement values of the
disturbed measurements.
Qm – Actual flow rate
6.4.3.7
Current actual flow rate (measurement flow rate)
The measurement inaccuracy of the displayed actual flow rate is
dependent on whether a pulse transducer or encoder is connected:
If a pulse transducer is connected:
For a maximum pulse interval of 15 minutes (at least four pulses per hour)
and
cp.I1 1, the measurement inaccuracy of Qm is maximum 1%. For a pulse
