Measured value no. Indicates which value from the OTT SVR 100 will be
recorded on this channel. Average flow velocity = 1,
Current flow velocity = 2, Sensor tilt angle = 3,
Flow direction = 4, Signal quality index = 5,
Vibration index = 6

; for measured values average flow velocity, cur-
rent flow velocity, sensor tilt angle, flow direction, signal
quality index and vibration index.

Concurrent Mode
☑
: instead of SDI-12 standard measuring mode (
M!
)
uses concurrent measuring mode (
C!)
).
This allows simultaneous measurement with multiple sen-
sors on a bus line (the sensors respond to a measure-
ment command without a service request). The sensors
must support version 1.2 or higher of the SDI-12 stan-
dard. Further information about Concurrent Mode can
be found in the SDI-12 standard; see "www.sdi-12.org".
This mode is useful if several sensors with a longer mea-
suring time and identical sample interval are connected
to a bus line.
䊳
Instantaneous value
☑
: If the OTT netDL If the OTT netDL receives an instan-
taneous value request (using LCD display and jog shut-
tle), it sends a command to start a current measurement
to the OTT SVR 100. Until this measurement is complete,
the LCD display uses the last measured value (or the last
instantaneous value displayed if this is more recent).
This is indicated by an "s" after the channel number
(sensor number) in the display. After completion of the
measurement, the new measured value appears with no
additional indication.
☐
: For an instantaneous value request, shows the last
measured value from the sensor (measured value from
last sample interval). This is indicated by an "s" after the
channel number (sensor number) in the display (see also
"OTT netDL IP data logger" operating manual, Chapter
9.1). This setting is not required on an OTT SVR 100.

Assignment of further measured values from the
OTT SVR 100 – that are not recorded on this channel –
to virtual terminals.

Notes:
䊳
Therefore, six channels on the OTT netDL are necessary to record all measured
values from an OTT SVR 100. The first channel contains the
SDI-12 Master
or
OTT SDI RS485
function block as the input signal. The second channel contains
a
vir tual sensor
(V02) as the input signal.
