Volume Conversion Device EK260

4.2 Application as high flow display device

The EK260 possesses an integral high flow display function with nationally certificated
type approval. Permissible values are:
the maximum volume at base conditions flow per measurement period within one
-
month
VbMP max,
the maximum volume at base conditions flow per day within one month VbDy max,
-
the maximum actual volume flow per measurement period within one month
-
VmMP max,
the maximum actual volume flow per day within one month VmDy max.
-
These maxima of the last 15 months can be saved in the monthly archive 1 (ArMo1).
The content of this archive can be called under the "Archive list" (→ Chapter 3.6, page 37).
The arising maxima of the current month can also be checked:
VbMP max and VbDy max in the "Standard Volume (Volume at base conditions) list"
-
(Chapter 3.1, page 23),
VmMP max and VmDy max in the "Actual volume (volume at measurement conditions)
-
list" (Chapter 3.2, page 25),
At the end of each month the "arising maxima" of the month just finished are written to the
latest data record of monthly archive 1. Along with this, the oldest data record is then
deleted so that monthly archive 1 always includes exactly 15 months.
The "end of the month" can be defined, i.e. it occurs on the first day of each month at an
adjustable time. As standard, this month boundary (= day boundary) is set to "06:00
hrs." and can be called up via the serial interfaces under the address "2:141" and changed
with the supplier's lock open, if entries are still free in the calibration logbook ( → page 42).
Any full hour of the day (0 to 23 hrs.) can be set.
As standard, the measurement period MPer is set to "60 minutes" and can be recalled in
the "Archive list" (Chapter 3.6, page 37) and changed with the calibration lock open.
Practical and normal values are 5, 10, 15, 20, 30 or 60 minutes.
