3 Device description
3.1 Functional principle
Devices of the type series AS 8 are display and control devices. The different
measurements and displays are defined via the variant selection.
The display unit is freely programmable after defining the variants. Program
using three buttons that are accessible after removing the front panel. For the
version with membrane keypad, the entry is made directly on the front panel.
Display and control units of the type series AS 8 process incremental input
signals from KRACHT flow meters and other transducers.
If the unit is operated with a flow meter that has one sensor, it is referred to
as single-channel sampling.
If the unit is operated with a flow meter that has two sensors, it is referred to
as two-channel sampling. The two-channel scanning facilitates a higher
measuring resolution and detection of the direction of the flow rate.
Two relays are always available for external subsequent processing. An an-
alogue output or a serial interface are available depending on the version.
Variants
Standard
The AS 8 standard version is a display unit for dynamic flow and volume
measurement.
The input signals are filtered in the unit, converted, and computed into the
physical sizes of flow rate or volumes.
