arrow keys. Push the RIGHT arrow key to advance to the next space.
Option Description
SELECT CHANNEL Shows the channels to be configured.
MODULE NAME Sets the name of the module.
RESET DEFAULTS Sets the configuration menu to the default settings. All
sensor information is lost.
CHANNEL A–D Sets multiple options for the desired channel.
3. For each selected channel, use the arrow keys to select an option and
push ENTER.
Option Description
SENSOR NAME Changes the name that corresponds to the sensor on the
top of the measure screen. The name is limited to 4
characters in any combination of letters, numbers, spaces
or punctuation.
FLOW FORMAT Sets the flow units, the multiplier and the resolution.
LOW FLOW Sets the minimal level for liquid flow. If the flow goes below
CUTOFF this level, a warning appears.
VOLUME UNITS Sets the units for volume (e.g., liters).
Option Description
TOTALIZER Sets the totalizer volume to Auto (default) or Manual.
MODE
TOTALIZER Resets the totalizer volume. Appears only if the totalizer
RESET mode is set to Manual.
FILTER Sets a time constant to increase signal stability. The time
constant calculates the average value during a specified
time—0 (no effect, default) to 60 seconds (average of
signal value for 60 seconds). The filter increases the time
for the sensor signal to respond to actual changes in the
process.
SELECT Sets the tee-mount sensor type.
SENSOR
SET SENSOR Sets the tee size and material. These settings are
dependent on each other.
LOG SETUP Sets the time interval for data storage in the data log—5,
FLOW 30 seconds, 1, 2, 5, 10, 15 (default), 30, 60 minutes.
LOG SETUP Sets the time interval for data storage in the data log—5,
VOLUME 30 seconds, 1, 2, 5, 10, 15 (default), 30, 60 minutes.
SERIAL NUMBER Sets the serial number of the sensor, limited to 16
characters in any combination of letters, numbers, spaces
or punctuation.
Calibrate the sensor
About sensor calibration
The sensor characteristics slowly shift over time and cause the sensor to
lose accuracy. The sensor must be calibrated regularly to maintain
accuracy.
During calibration, data is not sent to the datalog. Thus, the datalog can
have areas where the data is intermittent.
Calibration procedure
Note: If the controller is powered on when the paddle wheel sensor is not connected,
the calibration history is deleted.
