Operation

6.4.3.2 Values from Main tab

Vb – volume in base mode, see chapter 6.4.2.1
VmT – Total volume in operating mode, see chapter 6.4.2.2
p – gas pressure, see chapter 6.4.2.3
T – gas temperature, see chapter 6.4.2.4

6.4.3.3 K – Compressibility ratio factor

The compressibility ratio factor calculated is used to calculate the volume in base conditions.
The EK205 supports several equations to calculate the compressibility ratio factor. The
equation to be used is determined by the directives and standards applicable for the usage
area of the device. It can also be set when ordering or commissioning (



Setting the operating

6.4.3.4 C – conversion factor

The currently determined factor for converting the volume in operating mode to basic mode.

6.4.3.5 SReg – status register (total)

All messages since the last manual clear are collected in the status register. Here, it can be
seen what occurred since the last station inspection, for instance. The reports can be deleted
on the device (

Serv.

Clr

).

In the status tabs, only alarms and warnings (see chapter 8.2) are displayed.

6.4.3.6 VbMP



– maximum measurement period counter Vb in the current month

The time stamp of the maximum is displayed in the following row when moving the cursor to
the VbMP



value.

The maximum of the past 24 months can be queried in the monthly archive 1 (see chapter
6.4.4 Admin tab (administrator).

6.4.3.7 VbDy



– maximum day counter Vb in the current month

The time stamp of the maximum is displayed in the following row when moving the cursor
to the VbDy



value.

The maximum of the past 24 months can be queried in the monthly archive 1 (see chapter
6.4.4 Admin tab (administrator).

6.4.3.8 Qb – flow at base conditions

Current flow at base conditions (standard flow rate).
Qb = Qm



C

with

Qm

= actual flow rate

C

= conversion factor

The maximum imprecision of the value displayed corresponds roughly to the maximum
imprecision of Qm.
For alarm, Qb is calculated with the replacement values of the disrupted measurement
values.
