2.4.4 Optical data interface
An optical interface according to IEC 62056-21 with serial bit, asynchronous data
transmission is located on the front of the FLOWSIC500.
The interface can be used to read out data and parameter settings and to configure the
FLOWSIC500.
2.5 Totalizers
2.5.1 Device status and totalizers used
Various volume totalizers are fitted on the FLOWSIC500 depending on the configuration.
Meter V is used in the configuration as gas flow meter. If the gas flow meter has a
malfunction, the measured volume is also recorded in the error volume counter errV.
A gas flow meter Vm, a base volume meter Vb and a total volume meter Vbtot are used in
the configuration as gas flow meter with integrated volume conversion (device option). If
malfunctions occur, the measured values are not recorded in the base volume meter Vb,
but the converted volume is recorded in the malfunction volume encoder totalizer errVb.
Authorized users (user level “Authorized user”) can reset the error volume counters → p. 98,
§5.2.11.
2.5.2 Reverse flow
The FLOWSIC500 is designed as unidirectional and has a configurable zero-flow cutoff
which is factory set to a value of 1 m
3
(35 ft
3
) as default.
The totalizers are stopped during reverse flow and this volume is counted in a separate
buffer totalizer. When normal operation resumes, the buffer totalizer is first computed with
the flow rate.
The totalizers are first incremented again after the reverse flow volume has passed
through.
During reverse flow, the meter first switches to malfunction when the preconfigured buffer
volume has been exceeded. An error message is output on the device.
The zero-flow cutoff (measuring threshold for low flow rate) and the buffer volume (limit
value for reverse flow volume) can be adjusted with the FLOWgate
TM
operating software
during commissioning (→ p. 73, §4.3.2.3) or, after commissioning, in the “Warning” area in
the “Parameter Modification” menu.
