Step 4 - Sensor Configuration; Step 5 - Dimensional Entry - FlowLine EchoWave LG10 Series Quick Start Manual

STEP 4 - SENSOR CONFIGURATION

Configures the relays in terms of pump/valve operations and level alarms as well as the setting fail-safe for
relays and signal output.
STEP 5 – DIMENSIONAL ENTRY
Distance Mode (default): Output of sensor is based on the distance (height of liquid) in the tank. Any change
in liquid level will reflect linearly to the current output. The three values (Sensor Height, Probe Length and Fill-
Height) below set the 4-20 mA current span for the sensor. All values will be set in the units shown under
Height Units.
Height Units: Confirm units for use in Sensor Height and Fill-Height settings.
Sensor Height: Sets the location of the sensor above the bottom of the tank. It is based on the
distance from the Empty level position to the Top of the Threads of the sensor (see below).
Probe Length: Sets the physical length of the probe. It is based on the distance from the end of the
probe to the bottom of the mounting threads.
Maximum Fill-Height: Sets the location for 20mA. It is based on the distance from the Empty level
position to the Full level position (see below).
Minimum Fill-Height: Sets the location for 4mA. It is based on the distance from the Empty level
position to the bottom of the Probe plus 2" (The added 2" if due to the bottom dead band).

Loop Fail-Safe - Allows selection of
fail-safe current output if the sensor
looses echo confidence (LOST).
Note: Choose Hold Last Value
setting when your application level
either falls below the end of the
probe or rises above the Max. Fill-H
setting.
Output at Empty - Allows selection
of the orientation of the 4 to 20mA
output (4 to 20 mA or 20 to 4 mA).
Startup Condition – Allows
selection of the startup current
when power is first applied to the
sensor.
Probe Type – Allows selection of
the type of probe attached to the
feed-through. It is critical to select
the correct type of probe.
Dielectric Range - Allows selection
of the dielectric range, which sets
the amplitude threshold within the
sensor.
