1.5 Areas of application
The
essential
area of application
is the
recording and metering of flow rates
for custody transfer in natural gas flow measurement technology
.
The device can be delivered in two different versions of the software, each with a
separate approval as:
x
Status flow computer for natural gas (
ERZ2004-DI
)
x
Calorific value flow computer for natural gas (
ERZ2104-DI
)
Both variants can access the following for the K coefficient calculation:
k = constant, ideal gas, GERG88 S set A, GERG 88 S set B,
GERG 88 S set C, AGA NX 19 L, AGA NX 19 H, AGA 8 Gross Meth. 1,
AGA 8 Gross Meth. 2, GOST 30319.2, AGA 8 (1985),
AGA 8 92DC + AGA 10, AGA 8 (2017), GERG 2004, GERG 2008,
AGA 8 92DC + ISO20765-1, GOST 8.662-2009, GOST 30319.3
The ERZ2000-DI diction is superordinate and applies for both variables in the fol-
lowing text.
The special factory setting and sealing (
see chapter 1.5.2 Seal diagram for de-
vices with
MID approval
) is used for operation in custody transfer. In the process,
the function of the device must conform to the approval identified on the type plate.
Therefore, a subsequent modification of the device type is blocked.
Note
Modification of the device type is only possible under the supervision and
control of an officially recognized inspection authority or calibration offi-
cial. Then the necessary seals are also applied after the modification.
1.5.1
Use in gas measurement technology
The ERZ2000-DI is not intended for use in explosion-prone areas. However, it can
operate sensors and other devices in explosion-prone areas.
Only operate the ERZ2000-DI in fault-free and complete condition.
If you make technical changes to the device, safe operation can no longer be
guaranteed.
