About the FarSight
The FarSight is a non-contacting velocity sensor. The sensor provides
reliable flow velocity measurements using short pulses of micro-waves,
which are transmitted by an enclosed antenna. When reflected off a moving
surface, the signal experiences a shift in frequency characteristics. The
reflected signal is captured by the on-board microprocessor via the antenna
and analysed to determine the velocity.
The FarSight's compact and versatile design allows easy installation.
Housed in a robust enclosure coupled with a fully encapsulated microwave
antenna, it provides an effective fit-and-forget flow velocity solution.
PC software is available to allow setup and run diagnostics using MicroFlow
PC via a RS 485 connection. The FarSight is compatible for use with Pulsar
Measurement’s, FlowCERT, Velocity Interface and Ultimate controllers to
obtain velocity readings. The FarSight can also be retrofitted to replace
existing in-process contacting sensors. Overall, the device has outstanding
stability, accuracy, and repeatability.

Location
When choosing a location to mount the bracket and FarSight, note the
following:
• For optimum readings, it is recommended that the FarSight should be
positioned at an angle between 30° and 50° (45° being optimum) to
the surface of the material being measured.
• The mounting surface must be vibration-free.
• The ambient temperature should be between -40ºC and 80ºC.
• Ensure that the Pulsar Measurement Controller is installed in a “Safe”,
non-hazardous, area.
Mounting
For the best results, it is highly recommended to use the FarSight angled
bracket, which is available from your Pulsar Measurement distributor, which
will ensure that the FarSight can be correctly installed. The bracket can be
used if the FarSight sensor is to be mounted on its own in a specific location
or along with a Pulsar Measurement dB transducer. Please see ‘Angled
Mounting Bracket’ for dimensions of this bracket, please note that the
drawing is not to scale.
‘Mounting sensor to a bracket’ illustrates how you would install the sensor
to one of Pulsar Measurement’s angled brackets.
The bracket has 4 holes allowing mounting to a vertical surface by using
suitable fixings, or to a pole by using U-bolts.

Mounting Sensor to a Bracket
Mounting the sensor to a Pulsar Measurement 45° bracket (or optional
variable angled bracket) is done via an adapter and M20 nut, as shown in
the diagram below (Pulsar Measurement 45° angled bracket used in
example):
For correct installation, we recommend that the adapter or BReezTM is
threaded on the cable, and carefully screwed onto the FarSight before fitting
to the bracket. This will reduce the risk of any ’twisting’ in the cable.
Ensure that the sensor is tightened, and the dot is in the correct position.
Important Information
When fixing the sensor to the adapter, ensure that care is taken when pulling the
sensor cable through. And once attached to the adapter, and the M20 nut is
tightened, the green dot should be central to the movement of flow as shown in
Fig.4.

When the FarSight is mounted on the bracket with dB series level
transducer, the level measurement is made directly below the sensor where
the velocity measurement is taken from the water surface in view of the
FarSight. As these are different locations, it is important to have a uniform
channel shape when measuring flow via the Area*Velocity method.
Ideal installation for the FarSight would be when it has been installed to
monitor the flow moving towards the sensor. By default, FarSight reports a
positive reading when installed in this position.

CHAPTER 3 LOCATING THE FARSIGHT
For optimum accuracy install the FarSight where the flow is not turbulent,
and the flow direction is towards the sensor. An ideal location for the sensor
is in the centre of a long straight channel. Vertical drops, baffles, curves, or
junctions can cause the velocity profile to be distorted.
The FarSight sensor requires surface ripples to be present to provide a
reliable measurement. If there are no surface ripples within the sensors field
of view under any flow conditions, an alternative measurement point should
be found, or ripples created.
Locating the FarSight
• If the width of the channel exceeds 3m. Multiple FarSight sensors are
recommended to be used in conjunction with the Ultimate Controller.
• Ensure that there is an unobstructed path between the sensor and the
surface of the moving liquid being measured.
• Position the sensor at a height of 1m above maximum liquid level or up
to two times the channel width from the minimum liquid level, whichever
is greater. As shown below:
• A = Minimum 1m above Maximum Liquid level.
• B = Maximum 15m above Minimum Liquid Level.
B
A
Max Liquid Level
Min Liquid Level
FarSight
Page 26
FARSIGHT INSTRUCTION MANUAL
26
In the instance where there are vertical drops, baffles, curves, or
junctions, the sensor should then be positioned to aim at a straight part
of the channel, at a minimum distance that is at least five times the
width of the channel before a bend. Examples of positioning the sensor
are shown in the below diagrams.
Important Information
If the maximum width of the channel exceeds 3m, you may require more than
one FarSight sensor for your application, please consult Pulsar Measurement for
assistance.

Installing the Sensor
• The Sensor housing is designed to accept a 1-inch BSP/NPT female
threaded coupler for pipe or conduit.
• Ensure that the sensor is positioned at an angle between 30 - 50° to
the surface of the measured application, as this will achieve the best
results. An example of this is shown in the diagram below:
• When using one of the Pulsar Measurement Angled Mounting
Brackets, secure the bracket using the correct size screws/bolts/Ubolts (12mm diameter thread).
• Fasten the Breez
TM
adaptor to the FarSight, and then fix the 20mm
thread of the BreezTM to the bracket with the slotted nut. CAUTION:
Extreme over-tightening may crack or cause damage to the unit
or bracket.
• Position the sensor so the green ‘dot’ that is shown on the label
between the two green arrows is on the top of the device and is
central to the movement of flow in the channel.
• If desired, the sensor cable may be extended up to a maximum of
500m. Install the sensor cables in grounded metal conduit. Do not
run-in cable trays or duct banks with variable frequency drives or other
high voltage sources.
• When connecting multiple FarSight sensors for use with the Ultimate
controller. Ensure that all wiring in any junction /connector box is
correct.

• The sensor can be positioned to obtain readings following the
direction of the flow. Or it can be positioned to measure the
oncoming flow as seen below:
Preparation for Operation
Before switching on, ensure that the following is checked:
✓ FarSight is mounted correctly and is secure.
✓ All wiring is correct to a Pulsar Measurement controller.
✓ The power supply is correctly installed.
General Maintenance
There are no user serviceable parts inside FarSight. If you experience any
problems with the unit, then please contact Pulsar Measurement for advice.
To clean the equipment, wipe with a damp cloth. Do not use any solvents on
the enclosure.

CHAPTER 4 UNDERSTANDING HOW THE FARSIGHT WORKS
To set up and obtain flow readings using the FarSight, it is advised to do this
using a Pulsar Measurement controller.
Measuring streamflow / open channel flow
The calculation of flow using Area x Velocity is only possible when the
FarSight sensor is used as part of an integrated system with either FlowCERT
or Ultimate Controllers.
The calculation for the determination of discharge/flow in open channels
consists of different factors:
• Velocity of the liquid in the channel.
• Depth of the liquid in the channel.
• Cross sectional channel dimensions.
The flow is then calculated using the formula Q = V x A(h)
Where: Q = Flow rate
V = Velocity
A(h) = Area at head
Once the controller and the FarSight have been powered up, you can now
begin to program the controller to work effectively with the FarSight device.
On the Velocity Interface and the FlowCERT, the display provides different
levels of runtime information and a simple, progressive menu system in
program mode.
On the Ultimate Controller you can allocate up to 2 AUX displays to show
different levels of run time information.
Page 30
FARSIGHT INSTRUCTION MANUAL
30
FarSight Protocol
The FarSight uses a unique protocol to Pulsar Measurement’s noncontacting velocity sensors, which enables it to automatically work with the
Baud rate of any appropriate Pulsar Measurement controller that it is
connected to.
To enable the FarSight protocol to work successfully, please ensure that
the controller’s power is disconnected when connecting or disconnecting
a sensor the sensor.
Once the sensor is connected to the controller and power is restored to the
device, after a short period of time, the FarSight will automatically detect
and adjust its protocol and Baud rate to match that of the appropriate
Pulsar Measurement controller.
Page 31
PULSAR MEASUREMENT

CHAPTER 5 SETTING UP THE FARSIGHT
This chapter explains the quickest way in which to get your FarSight sensor
working with the Pulsar Measurement controllers that the sensor operates
with.
FlowCERT Setup
1. Install and connect your FlowCERT controller as outlined in the FlowCERT
user manual.
2. Install and connect your FarSight sensor to the FlowCERT as described in
Chapter 2 - FlowCERT Wall Mount of this manual.
3. Power up the unit and enter program mode by keying in ‘1997’ and
pressing Enter to set-up an application for ‘area velocity’. This can be
done by choosing option 4 in Quick set-up or directly changing P700 to
4 = ‘Area velocity’.
4. Continuing with the Quick setup, you now need to select the Primary
Measuring Device (PMD) for your application from the options displayed
on screen.
5. Once you have selected your application you will then be asked a series
of questions, which are answered by selecting the appropriate option
you require. For further information on the Quick set-up of a FlowCERT
please refer to Chapter 6 Quick Set-up Guide in the FlowCERT user
manual.
6. Once you have selected area velocity, set P130 ‘Device Mode’ to 2 =
‘Speedy’ (‘Velocity’ in Ultra firmware versions 7.4.4 and onwards) to
enable the velocity parameters.
7. To change the maximum flow velocity of your application you will need
to set P683 ‘Maximum flow velocity’ to the desired value (in m/s)
8. To change the minimum flow velocity of your application you will need
to set P682 ‘Minimum flow velocity’ to the desired value (in m/s)
9. All other velocity parameters can be left at their default values or can be
adjusted to suit the application, i.e., ‘P688 Gain’ and ‘P684 Damping’ can
be altered to the value range outlined in Chapter 7 – Parameter Listing
and Descriptions of this manual.
10. When a level transducer is also connected, to view the instantaneous
flow velocity measurement on the auxiliary display of the FlowCERT,
P815 ‘Auxiliary Source’ should be set to 1 = Velocity.
Page 32
FARSIGHT INSTRUCTION MANUAL
32
The auxiliary display will then alternate between displaying the flow
units and the current flow velocity. Please note that the instantaneous
flow velocity cannot be displayed in the auxiliary display when the resettable totaliser is selected.
11. If no further changes are required, return to run mode and after a short
time the flow readings from the FarSight will be displayed on the
FlowCERT screen.
Velocity Interface setup
1. Install and connect your Velocity Interface controller as outlined in the
Velocity Interface user manual.
2. Install and connect your FarSight sensor to the Velocity Interface as
shown in Chapter 2 - Velocity Interface of this manual.
3. Power up the unit and enter program mode by keying in ‘1997’ and
pressing Enter to begin setting up the unit for measurement.
4. If you wish to change or view the velocity measurement units, set P130

CHAPTER 6 MICROFLOW PC
The software that accompanies the FarSight can be used to setup, test,
obtain and record readings from a sensor. To utilise the features of the
software, an RS485 connector, which is available from Pulsar Measurement
(as shown below), is required to communicate between the sensor and your
machine.
If a Pulsar Measurement controller is installed, common setup parameters
can be programmed directly from the controller, such as ‘Gain’ and
‘Damping’. This chapter outlines how to install the software onto your
machine and how to use it with your FarSight.
Software installation
Insert the USB that accompanies the FarSight sensor into your PC/Laptop. If
you do not have a USB on your laptop, then this software can be
downloaded from the Pulsar Measurement website:
https://pulsarmeasurement.com/downloads and choose Software and select
to download Microflow PC from the list which will then be downloaded onto
your machine. When setting up the RS485 connector for the first use, the
necessary drivers for it to operate correctly with your OS will be installed
from your installation of the MicroFlow PC software from the USB
accompanying the sensor, or the software can be downloaded from our
website for free. Once downloaded, a shortcut icon will be created onto
your Desktop for ease of use. Double click on this icon to launch the
program.
For optimum installation insert your RS485 connector to your PC whilst
installing the drivers, where your PC should assign it to a Com Port.
Or if you have an internet connection, upon inserting the USB of the RS485
connector for the first time, Windows updates should install this onto your
computer for you. Once the driver’s installation has completed, remove the
RS485 connector from your machine. Your RS485 connector is ready to be
used when a connection to MicroFlow/FarSight PC is required.
Page 37
PULSAR MEASUREMENT
37
Using MicroFlow/FarSight PC
To connect to the software using the RS485 connector, power to the sensor
can be obtained from the compatible Pulsar Measurement controller is
connected to.
With the two FarSight RS485 cables removed, connect the Red wire with the
Red crocodile clip on the connector, to the Orange (RS485+) wire of the
FarSight. And connect the Blue wire with the Black crocodile clip on the
connector to the White (RS485-) wire of the FarSight, as shown below:
Once the sensor is connected to the RS485 connector, insert it into the
PC/laptop ready for use, and ensure that your sensor is switched ‘ON’ to
enable the software to communicate with the sensor.
If you know the Com port that the RS485 connector is assigned to, please
select Setup > Serial Port to enter the Com port number to the device.
Once you have selected the correct Com port number, selecting ‘Connect to
device’ will allow the software to connect to the RS485 connector Com port.
If the Com port number was not known, unchecking Use Setting under
Serial port will search for and connect to it automatically.
After launching the program and connecting to the FarSight, the application
name will change to FarSight PC. The device parameters will be
automatically extracted once a connection is established. Once connected
you can now view the information received from the sensor on the
Software’s individual tabs: Flow, Flow Record, Trace and Parameters.
Important Information
Ensure that power to the controller/sensor is switched ‘OFF’ before removing
cables and any connection is made.

Flow Tab
The above picture is the default screen of FarSight PC, which is the Flow tab.
The dial on the left displays the reported flow velocity (up to 6m/s), which is
in metres per second. The numerical display near the Velocity label shows
the Reported velocity flow rate (in bi-directional mode the velocity moving
away from the sensor will be indicated as a negative value) in different
volume and time units. The values displayed on the right also appear on the
PC software’s other tabs to help diagnose the information seen on the
individual tabs. Below the Reported Velocity, there are two dropdown boxes
where you can adjust the values to read different measurement units and/or
time units. Measurement units can be changed to either metres, millimetres,
or feet. The time units can be changed to seconds, minutes, or hours. The
default for distance and time units is m/s. Provided below are the various
options shown under the Flow tab:
Page 39
PULSAR MEASUREMENT
39
Velocity (Reported Flow Velocity)
The reported flow velocity is the flow reading reported by FarSight displayed
in the larger numerical box near the Velocity label. It can show positive or
negative flow value depending on the selected direction for reported flow.
Refer “Chapter 7 - Configuration parameters” for more information.
Inclination
This indicates the angle (with the horizontal axis) at which the FarSight is
mounted.
Signal Strength
The signal strength gives an indication of the actual strength of the velocity
signal detected. A level of higher than 70% is desired for reliable operation.
Stability
The stability level is an indication of the consistency of flow reading, as
derived from the combination of signal strength and statistical fluctuations
of the flow reading. A high level of stability would indicate optimum
condition, and relatively healthy flow within the channel and indicate higher
levels of repeatability and better flow tracking. The stability does not
necessarily indicate the accuracy of the flow reading, as this is subject to
calibration.

manual.
Page 45
PULSAR MEASUREMENT
45
Trace Tab
This displays the diagnostic traces from the sensor when the trace button is
activated or when replaying a saved file. The vertical axis is related to the
signal strength, while the horizontal axis is related to the detected flow.
Since the trace for FarSight includes bidirectional data, the toward
directional trace is from the flow index 0 to 126, whereas the away
directional trace is from the flow index 127 to 253.
When a signal is received, the ‘green square indicator’ will move down
from 15 on the vertical axis. The further the ‘green square indicator’ moves
from 15, the larger the strength of the received signal. During flow
condition, the ‘green square indicator’ will normally be within the range of
25 to 80. Under no-flow conditions the ‘green square indicator’ will remain
at 15.
When a flow is detected in the toward direction, the ‘red circle indicator’
(Toward index) will move horizontally from left to right (0 to 126) to indicate
toward flow detection, whereas when a flow is detected in the away
direction, the ‘red circle indicator’ (Away index) will move from right to the
left (253 to 127) to indicate away flow detection. Both the ‘red circle
indicators’ should stay at 0 under no-flow conditions and move along the
horizontal axis when flow is detected.
Toward Flow
Away Flow
Page 46
FARSIGHT INSTRUCTION MANUAL
46
Under flow condition, the line should still approach and flatten out at just
below the signal index 15 line (By default).
If the trace remains flat or the indicators struggle to remain stable during
flow, then increase the ‘Gain’ (P102) setting.
You are also able to see the current velocity measurement obtained by the
sensor in the chosen volume and time units selected.
Parameter Tab
This tab enables the user to change parameter settings in the FarSight
sensor. It is important to note the following to ensure that the sensor is
correctly programmed.
Upon every connection to the sensor, FarSight PC will synchronise the
values on the Parameter tab to that currently stored on the sensor, including
the Modbus ID of the sensor. Changing a parameter can be done in one of
two ways:
1. Selecting the parameter and then entering/choosing a value from the
options available when highlighting the box.
2. Using the Manual Setting parameter box.
Page 47
PULSAR MEASUREMENT
47
The option for manually setting the parameters can be done by utilising the
Manual Setting terminal on the parameters tab, as shown below:
All parameters can be queried by entering the parameter address in the
Parameter field and then clicking on the Query button. The FarSight will
then reply with the current value of that parameter.
For setting a parameter, both the Address and Value must be entered
before clicking on the Set button. ‘User’ will show the value you have
changed in the manual setting box. And ‘UI’ will appear when changing a
parameter via one of the parameter dropdown selection boxes. The
appropriate access levels are required for setting parameters. After
changing any parameter, the ‘SAVE’ button must be clicked to send and
save the new values to the device. If the change is not successful, then the
values that are shown on the Parameter tab will reflect the current
parameter value on the sensor.
Important Information
Ensure that the correct parameter/register number is known before making
changes to any of the parameters and their values.
Page 48
FARSIGHT INSTRUCTION MANUAL
48
The values need to be valid and within the allowed range for that parameter
change to be successful. Please refer to ‘Chapter 7 Parameter listing and
Descriptions’ in this manual, on the parameters available and the range
each one can be set between. If a parameter has been incorrectly set,
highlighting the ‘Default’ box, and selecting any of the options from the
drop-down list will display that parameters default box. This shows the
parameter number, its current value, and the default value of that individual
parameter. Select ‘OK’ and then ‘SAVE’ to store that value.
If the FarSight is being controlled simultaneously on both FarSight PC and
RS485 via Modbus interface, the values on the Parameter tab will not be
instantly updated on FarSight PC if a parameter change is instructed via the
RS485 Modbus.
Page 49
PULSAR MEASUREMENT
49
CHAPTER 7 PARAMETER LISTING AND DESCRIPTION
Parameter Access
All the FarSight sensor parameters have factory default values which the
user receives upon first use, or when the sensor is reset. The parameters
consist of two main types: Output parameters and Configuration
parameters.
Output parameters are read only and cannot be set by the user. Examples
are the stability and signal strength. Configuration parameters can be
queried and set, there is also an associated access level required for setting,
either ‘User’ or ‘Service’. Upon connection to a sensor, the access level is
defaulted to ‘User’.
The parameters are always stored and entered as whole numbers, please
refer to the individual parameter for its individual value range.
The naming syntax for the parameters is with a prefix of ‘P’ before the
address. For example, a parameter at address 102 is “P102”. The
value/content of the parameter is delimited by a colon “:”, such that
“P102:20” indicates that the parameter at address 102 has a value of 20.
The terms “parameter” and “register” are used interchangeably as the
parameter number is the actual address of the storage register.
The parameters on the FarSight can be accessed using either:
• The parameters tab on FarSight PC.
• Modbus RTU communication protocol (RS485).
It is recommended that only one method of access is used at any point in
time.
Page 50
FARSIGHT INSTRUCTION MANUAL
50
Output parameters
Using a Modbus Master, output parameters can be polled using Read Input
Registers. For example: To view the flow velocity, you would read register
(parameter) addresses 30020 and 30021.
Toward Flow Velocity P20 and P21
The current flow velocity in the toward direction (flowing towards the unit)
can be read from registers 20 and 21, in the following format:
P20 contains the whole number part of the flow reading, while P21 contains
the fractional part of the flow reading. P21 is stored as a whole number
from 0 – 999 (allowing a fractional representation of 0.001 to 0.999).
Away Flow Velocity P30 and P31
The current flow velocity in the away direction (flowing away from the unit)
can be read from registers 30 and 31, in the following format:
P30 contains the whole number part of the flow reading, while P31 contains
the fractional part of the flow reading. P31 is stored as a whole number
from 0 – 999 (allowing a fractional representation of 0.001 to 0.999).
P22 Signal Strength
This is a ‘read only’ parameter and gives you the current signal strength in a
percentage, from 1 to 100.
P23 Stability
This is a ‘read only’ parameter and gives you the current stability in a
percentage, from 1 to 100.

Changing this to ‘Fast’ will
automatically calibrate
parameters in the FarSight
sensor to track
measurements faster. This
is recommended for
Pumped flow. ‘Slow’ is
recommended when there
is natural flow, as
measurements will be
tracked at a slower pace.
River mode is
recommended for river
applications. Instant would
be suitable for Battery
Loggers. The fastest to the
slowest response is as
follows: Instant, Fast,
Medium, Slow, River.

7 – This resets all FarSight
parameters to their
default values. (It does
not affect any mA Trims
applied).
If using the FarSight on an application where flow type is changed
to ‘Fast’, this will reduce the damping to obtain better results. If
there is natural flow and ‘Slow’ is chosen, then damping is
increased to obtain better results.

Saving & Loading parameters
For a device where parameters are heavily customised, the user may wish to
replicate such customisation on a second device. Saving and loading
parameters can be used to avoid having to set-up the parameters
individually again:
1. Connect FarSight PC to the first device, then select System->Save
Device Parameters.
2. A confirmation message will appear, and the parameters saved to a
file within the default folder (use Info > Data Folder Path to see the
folder location). The filename is prefixed by “ParamFarSight-”
followed by the date and time.
3. Connect the second device to FarSight PC, to load the parameters
on to. Select ‘System > Load Parameters to Device’, then choose
the parameter file to load.
4. The unit will disconnect from the software, and a message box will
appear asking to confirm the parameter change, and once
completed another message box will appear informing you that the
parameters have been loaded onto the sensor correctly.
5. Once the parameters have been loaded onto the sensor, it will
automatically re-connect to the FarSight PC software, where you
are able to see the new parameter values.

Firmware Upgrade
Ensure that any customised parameters are saved before any firmware
upgrade is undertaken. Firmware upgrades are performed in ‘Bootloader’
mode. Note that all flow measurement and output operation will be halted
when the sensor is in the ‘Bootloader’. Please follow these steps:
1. Please ensure that the sensor is connected to a PC via the RS485
port. Prior to reprogramming, you will need the firmware file, and
the COM port number of the RS485 connector.
2. Establish a connection to the sensor, and it is advisable to save any
customised parameters before beginning an upgrade.
3. You will require Service access to switch the device into Bootloader
mode, and to activate Bootloader control.
4. First place the device into bootloader mode by selecting System >
Switch Device into Bootloader.
5. Select System > Bootloader control, which will launch the
Bootloader interface. As seen in Fig.9.
6. Once connected click ‘Load Hex file’ and choose the firmware file
you are using to upgrade the sensor.
7. Click ‘Erase-Program-Verify’ and wait for the process to finish.
8. When the ‘Verification Successful’ message is displayed, click ‘Run
firmware’ and the Bootloader Interface will close.
9. Select the ‘connect’ button on the software, and the sensor will
reconnect to FarSight PC with the new firmware installed.

Important Information
If the sensor does not connect to the device within 40 seconds, it will resume its
normal operation with its current firmware.
Do not switch off supply to the unit or close the software during the firmware
upgrade.

CHAPTER 8 TROUBLESHOOTING
This section describes many common symptoms, with suggestions as to
what to do. If the issue persists, please contact your local Pulsar
Measurement distributor.
SYMPTOM
WHAT TO DO
FlowCERT/Velocity
Interface/Ultimate shows ‘Lost
Comm’
Check power supply. Check wiring to the
FarSight sensor. If sensor has been
connected to a new unit, then it may
require power cycling to sync with the
controllers Baud rate.
Currently the velocity reads zero,
but you know that there is flow
movement.
Ensure that the sensor is mounted correctly
in accordance with Chapter 2.
Current velocity reading is
higher/lower than known
movement of flow
Check that the sensor is mounted correctly.
Adjust the Gain (P102) or Damping (P109)
parameters to obtain correct
measurements.
Unable to connect to FarSight PC
Check that wiring to the RS485 connector is
correct. Close FarSight PC, cycle power on
the sensor re-open FarSight PC and retry
connection.
The velocity is not moving to the
correct flow peak index/the flow
peak index is jumping between
peaks.
Adjust ‘P125 Response’ to match your
requirements (Refer Chapter 7).
FlowCERT reading is not showing
the negative reported flow velocity.
FlowCERT parameter ‘P682 Min Velocity’
should be adjusted to show negative flow
reading.
FlowCERT reading is incrementing
slow on the display.
Adjust ‘P687 Stability’ on the FlowCERT
controller, to a smaller number than 12, i.e.,
8.
