Display of the mains frequency for the flow-
meter primary. Selections only available for
„Older Model".
Display of the type of flowmeter primary
connected.
Display of the flowmeter primary size.
Selections only available for „Older Model".
Display of the reference voltage value only
for „Older Model", see type tag on the flow-
meter primary. Not displayed for Model
10D1422.
Display of the max. possible flow range . Au-
tomatically selected from the flowmeter size
selection.
Flow range end value for forward and
reverse flow directions. Flow range end val-
ue range can be set between 0.5 and
10 m/s.
Response time, after 1τ the displayed
value has reached 63% of its actual value
(after 5τ).
Applies to the values displayed and all
outputs. The switch point has a built in
hysteresis off 0.1 % .
Information!
Only if the meter pipe is completely filled will
a correct measurement be made. The func-
tion "Detector empty pipe" can be used to
continuously monitor this condition. If the
fluid level drops below the electrode level,
then all outputs can be automatically set to
zero. Thereby erroneous pulses and indica-
tions can be avoided when the meter pipe is
empty. When the meter pipe is full, the error
message „empty pipe" is turned off and the
systems returns to normal operation.
Turn the empty pipe detector on or off. Not
available for meter sizes:
1 mm 1/25 in
1.5 mm 1/17 in
2 mm 1/12 in
3 mm 1/10 in
4 mm 5/32 in
6 mm 1/4 in
8 mm 5/16 in
Information!
Empty pipe detection is not available for
flowmeter primaries with preamplifiers.
