Total Flow
Measurement
As well as averaging measurements to display flow rate, the flowmeter totals all
measurements divided by the measurement period to compute a totalized flow. This is
written to the display at the same configured intervals as for flow readings.
The units of measure for total flow can be configured independently of flow rate.
The accumulation of the total flow is affected by the configured Low Flow Cutoff and
High Flow Cutoff value values. Smaller and larger flow rates, respectively, never
contribute to the total.
Pressing the
CLEAR
soft button zeros the total accumulated flow if this option has been
enabled by the configuration.
Should the flowmeter experience a power loss or be restarted by entry into
Setup Mode
,
it will preserve a recent value of the total flow and restore this when next entering
Run
Mode
. In
Run Mode
, the Total Flow will be saved to non-volatile memory every ten
seconds. On entering
Run Mode
, the initial value of the Total Flow will be the most
recent value stored. Any fluid that flows while the flowmeter is not in
Run Mode
and
after the value was last recorded is not included in the total. Only one total is saved, so
that the same total will be restored even if the active
Configuration Set
is changed or
configuration changes are made. To clear the total to zero, you must enable the clear
function and press the
CLEAR
soft button as described above. Either the Model S2
display, the Model S3 display or theCommunications Board must be fitted, and the clear
total function must be enabled in the
Factory Configuration
, to zero the total value.
The top line of the
Run Mode
screen shows the status of the measurement process. On
the far left is shown the active
Configuration Number
, active
Measurement Mode
and the
Transducer Separation Distance
. In the center is shown the
Goodness of
Measurement
index. On the right is shown the
Speed of Sound
in the fluid (if in
transit time mode).
