1. Introduction
This Quick Start Guide describes the installation of the EchoFlo and
interfacing with a Series 3 FloPro or HydroMace 3000.
The EchoFlo system consists of four components:
• TheEchoFloultrasonicsensors(1.25mor2.5mrange)
• TheViton®Gasket
• TheUSB®congurationinterface(Fob)
• EchoCalsoftwareenablingyoutocongureyourEchoFlo
IMPORTANT: The minimum version of EchoCal required to communicate with the EchoFlo is Version
5.17.0 The version number is displayed on the EchoCal program banner. The latest version of
EchoCal is available for download from www.macemeters.com

2. Communicating with EchoFlo
EchoFlocommunicateswithEchoCalusingaUSB®interface called a Fob.
1.InstallEchoCalonyourcomputerbydoubleclicking
“MaceInstallerverX.X.X” icon and following the prompts.
ECHOCAL SYSTEM REQUIREMENTS: Windows® XP, 10 MB hard drive space, 256 MB RAM,
One USB® 2.0 port, Internet connection.
2.Connectthered,green,whiteandblackwiresfromEchoFlointothe
correct terminals on the Fob. Tighten the screws on the terminals and
plug your Fob into the USB®port of your computer.
WARNING: Before plugging the Fob into your computer’s USB®
port, you MUST install EchoCal on your computer.
WARNING: Once EchoFlo is
congured, DO NOT touch
the white wire to positive (+).
Doing so can cause permanent
damage to the unit.

A typical ow measuring application in a
partially full, closed pipe is shown below.
TheMACEEchoFlo(mountedonthetopof
thepipe)measuresthedepthandaMACE
Doppler sensor (2” insert) measures velocity.
Together, these two sensors are connected
to a Series 3 FloPro that calculates, records
and displays the resultant ow rate.

4. Position and Mount
Positioning and mounting EchoFlo is critical to the sensor performing
correctly. EchoFlo should always be mounted perpendicular to the
liquid in the pipe or tank, clear of any obstructions in the beam path.
Not doing so will result in poor performance.
Mounting Guide
IMPORTANT:
1. Do not mount at an angle
2. Liquid should NEVER enter the deadband
3. Mount at least 2” from the side wall
4. When pipe mounting, always install such that the bottom of the
pipe is within the sensor’s range
5. Do not mount where obstacles will intrude on 2”beam width
6. Do not mount in a vacuum
7. Never screw directly into the pipe or tank, ALWAYS use a
NON-METALLIC tting
8. Always use an adapter with the minimal height possible

clicking “Wiring Diagram”.
NOTE: Be sure to record the“Sensor Height” and “Fill Height”
before exiting EchoCal as these will be needed during the
calibration process.
3. Conguring EchoFlo
1.Startfromthetopofthe“Cong”areaofEchoCal and work to the
bottom, choosing the selections that are applicable.
NOTE: If the sensor is already congured
with a Frequency output and it needs to
be changed to a Voltage output (or vice
versa) click“Clear Screen”.
2.Allcongurationsettingsmustbeselected

the height.
Stand Pipe:
Use a stand pipe when
surface foam or turbulence
are present. Use a 2”
diameter pipe or larger
with a length that runs the
distance of the span. Cut
a 45º notch at the bottom
and a 1/4” hole within 2”
from bottom of the sensor
face.

WARNING: Once EchoFlo is congured, DO NOT touch the
white wire to positive (+). Doing so can cause permanent
damage to the unit.
1. The maximum cable run is 30m (66ft).
2. Three-core shielded instrument cable should be used for
extended cable runs.
3. A waterproof terminal box should be used when
extending the cable.
4. The USB Fob will ONLY operate through the standard
cable length of 1.2m (48”).
NOTE: Ensure that the cable attached to the EchoFlo is not
permanently terminated so that it can be accessed for any
future conguration changes.
NOTE: The remaining sections of this guide describe the
detailed wiring, conguration and calibration of an EchoFlo
with a MACE Series 3 device.

7. Calibrating an EchoFlo“Depth”
channel using FloCom+
AfterfollowingthepreviouscongurationstepstheEchoFlomust
be calibrated. Table 1 below lists relevant information for both
EchoFlo models including the “Slope” and “Oset” values for sensors
conguredovertheir“Eective Sensor Range”.
TABLE 1: EchoFlo Slope and Oset Values

3. The “Channel name” dialogue
box will appear. Enter a channel
“Name”intothetexteld
(16 character maximum). This
“name” will also be displayed on
theSeries3devicemainLCDif
enabled.Click“Continue”.
2. Select “Congure Channels” and click
“Add” and the “New Channel” dialogue
box will appear. Select the “Depth”
channel type and click “Continue”.
4. In the “New channel” dialogue
box highlight the “I/O Module”
option from which the named
channel will receive its value.
Click“Continue” and a new
dialogue box will appear with
the available input types listed.
5. Select the “Frequency” input
type from the “I/O Module @ 2”
list.Click“Continue” and then
select the appropriate input
from which the named channel
will receive its value.
6. In this example the channel
named “EchoFlo Depth” will
be calculated using a sensor
attached to “I/O Module @ 2”
on “Digital input #1”.Click
“Continue” to complete the new
channel.
6. The “Congure channels”
dialogue box will re-appear
with the new channel listed.

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congure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

8. Safety
1. Installation should be undertaken by properly trained sta
2.SupplyvoltageshouldNEVERexceedamaximumof24VDC
3. Make sure the sensor is chemically compatible with your
application
4. Design a fail-safe system that accommodates the possibility of
sensorand/orpowerfailure.
5.Thissensorshouldnotbeusedinclassiedhazardous
environments
The Slope and Oset values of the installed EchoFlo are dependent
on the “Fill Height”asenteredduringtheEchoCalconguration
procedure.
NOTE: The following calculations are based on the EchoFlo
being congured with a frequency output.
Manually calculating Slope
Slope = Fill Height ÷ Sensor Span
Sensor Span: Is the dierence between the sensor output at the top
of the “Fill Height”(2000Hz)and the sensor output at the bottom
(976Hz).ThefrequencyoutputofanEchoFlohasaspan
of1024Hz.
Manually calculating Oset
 Oset=-(SlopexSensoroutputatzero)
Metric example - you wish to calculate the slope and oset for an
EchoFlothathasbeenconguredwitha“Fill Height” of 0.75m (75cm).
Thefollowingcalculationswillprovidethesensor’sslopeandoset:
Slope = 0.75 ÷ (2000-976)
= 0.75 ÷ 1024
= 0.00073
Oset = - (0.00073 x 976)
= - 0.71484
US example - you wish to calculate the slope and oset for an EchoFlo
thathasbeenconguredwitha“Fill Height” of 30”.
Thefollowingcalculationswillprovidethesensor’sslopeandoset:
Slope = 30 ÷ (2000-976)
= 30 ÷ 1024
= 0.02929
Oset = - (0.02929 x 976)
= - 28.59375
NOTE: Be sure to record the relevant “Slope” and“Oset”
values.
Calculating the EchoFlo Slope & Offset
The “Oset adjust” functionisusedtonetunethedepthreading
whenever the sensor is deployed.
1.Click“Oset adjust” from the
“Edit channel” dialogue box and the
“Channel oset adjust” dialogue box
appears. The “Current value” from the
sensor is displayed at the top of the
window and is updated approximately
once per second.
2. To adjust the “Current value”, enter your current measured value
in the “Corrected value” eld.
3.Clickonthe“Apply” button to calculate the new “Oset”
parametervaluefortheassociatedchannel.Clickingonthe“Cancel”
button terminates the procedure without altering the oset value.
WARNING: When calibrating a depth channel, measurements
should ALWAYS be carried out from the BOTTOM of the
channel/pipe to the top of the water level
1. In the “Congure
channels” dialogue box
click “Edit” and the “Edit
channel” dialogue box will
appear. Enter the relevant
“Slope” and “Oset” values
as determined using the
previous calculations.
