trode wires and the flowmeter
can indicate totally random val-
ues. To avoid this situation, the
sensor can be equipped with
checking electrode and con-
verter with full pipe check mod-
ule. The module continuously
checks if the checking electrode
is immersed in liquid. If it is not,
an error message will be dis-
played and zero flow rate will be
indicated. The checking elec-
trode is connected to terminal 1.
This electrode cannot be retro-
fitted and should be con-
sidered on initial order.

Batching
Batching mode is used for
control of external equipment
( valves, pumps) in order to
measure repeatedly the preset
volume (batch). It is not recom-
mended for batching of very
small volumes. The period of
one batch has to be min 30 s.
Electromagnetic flowmeter
FLOMAG3000 has very sophis-
ticated batching functions. It
enables simple batching with
manual starting but also fully
automatic batching by remote
control.
Batching process is divided
into 4 phases. Single phases
are distinguished on LCD by a
symbol in square brackets. Up-
per line shows remaining vol-
ume in ml to the end of the
batch. Bottom line shows help
for manual batch control.
Phase 0 - Stop
During phase 0 outputs are
inactive, no batching runs, wait-
ing for start of the batching
process. Manual start is real-
ized by holding button
3
and
simultaneous pushing of button
4
or from outside with the help
of module E in Batch Start
mode. During that phase the
batch volume is set. To enter
edit mode it is necessary to
hold button
2
and simultane-
ously push button
4
.
Phase 1 - Hold
Phase 1 temporary batch in-
terruption. Outputs give signal
for interruption of the batch
(close valve, switch off pump).
Counted batch could ve contin-
ued again by manual start
choosing Restart or from out-
side with the help of module E
in Batch Start mode. It is possi-
ble also to abort the batch by
choosing Reset or from outside
with the help of module E in
Batch Stop mode.
Phase 2 - Run
During that phase runs the
measuring of the batch (valve is
open, pump is running). This
mode can be interrupted using
Phase 1 (Hold) activated manu-
ally or with the help of module E
in Batch Stop mode. It is possi-
ble also to abort it choosing Re-

Module G1
Module H1
Module G1 is a GSM modem
enabling sending by SMS mes-
sages on preset numbers, in
preselect intervals (or on re-
quest) inforamtion about the
status of the flowmeter and the
measured values. Detailed de-
scription of the module func-
tions is given in a separate
document.
Module H1 is Bell 202 mo-
dem, extensioning the function
of modules A6 and A7. It en-
ables data communication
through current loop with a pro-
tocol compatible with HART
(only Universal Command). As-
signing the variables of the
flowmeter is following:
PV - Flow rate [ l/s ]
SV - Current flow rate [ l/s ]
TV - Total [ m

/h ]
QV - Total volume - [ m
