5-6-10 : Setting drop out
This function is used to set the drop out value for the pulse output. The pulse output
will be cut off at this point to avoid flow pulsation in range values close to zero, thus
preventing incorrect totalization of the flow rate.
Pulse counting pauses when the flow rate reaches this preset percentage of the set range.
The low flow cutoff function affects the drop out function of the MagneW Two-wire
PLUS+. Please refer to the following table describing how the drop out function of the
MagneW Two-wire PLUS+ works.
Drop out function of the MagneW Two-wire PLUS+
LFC: Low flow cutoff, DO: Drop out
Setting range: 0 to 10%
Default: 2%
Set drop out in accordance with the following procedure:
Area
LFC setting value > DO
setting value
LFC setting value < DO setting
value
Pulse output When the flow rate is less than
the LFC setting value, the pulse
output is fixed to zero (does not
generate pulses). When the flow rate is less than the
DO setting value, the pulse output is
fixed to zero (does not generate
pulses).
Built-in counter
(Totalized
value) When the flow rate is less than
the LFC setting value, the
totalized value is not counted up. When the flow rate is less than the
DO setting value, the totalized
value is not counted up.
