After following the previous configuration steps the EchoFlo must
be calibrated. Table 1 below lists relevant information for both
EchoFlo models including the
“Slope”
and
“Offset”
values for sensors
configured over their
“Effective Sensor Range”
.

input
type from the
“I/O Module @ 2”
list. Click
“Continue”
and then
select the appropriate input
from which the named channel

6. Configuring an EchoFlo “Depth”
channel using FloCom
+
The EchoFlo is connected to a MACE Series 3 device by plugging the
pre-wired terminal strip into an I/O card within the device.
1.
Using MACE FloCom
+
software, connect to the device using the
serial port and configure the following settings:
• Enable
“Sensor power”
and select at least a 20 second warm up
time (a longer period may be required to record a stable reading
in some applications).
• Add an I/O module
NOTE: Refer to the relevant MACE Series 3 product manual for
detailed instruction on the above steps
