Terminal Connection Detail
Power
The Flow Monitor can be powered from mains AC or from a DC
source/battery and where a backup DC power source is connected it will
automatically take over in the event of AC power failure; DC will
automatically power the unit. When AC returns it will switch back.
FlowPulse Sensor
The FlowPulse sensor should be installed and connected, in accordance with
the FlowPulse manual.
Wire the FlowPulse sensor to the Flow Monitor sensor terminals, as on the
previous page.
Relay Outputs
The two relays can be programmed to a variety of alarm & control functions.
The relay contacts are all rated at 2A at 240V AC. All connections should be
such that the short circuit capacity of the circuit to which they are
connected, is limited by fuses rated so that they do not exceed the relay
rating.
Current Output
This is an isolated active mA output of 4 - 20mA or 0 - 20mA, with an option
of a passive mA output. The load should not exceed 1K.
RS485 termination switch
By default, this is switched off, to enable RS485 termination both switches
need to be switched to the ON position.

There are two main operating modes for your Flow Monitor, Run Mode and
Program Mode. There is also a Test Mode, used for checking the set-up. All
modes are now described.
Run Mode
This mode is used once the Flow Monitor has been set up in program mode.
It is also the default mode that the unit reverts to when it resumes operation
after a power failure.
When the Flow Monitor is switched on for the first time, it will attempt to
initiate the FlowPulse sensor and will display a message similar to
“Update….” and follow by parameter number. All relays by default are
switched off and once the FlowPulse is initialised, the display will show the
current flow or velocity and the measurement unit.
After programming is complete, any relays that are set will operate when the
measurement reaches the relevant setpoint.
LED’s
There are two LED’s that can be seen through the lid of the Flow Monitor
enclosure, which will indicate the operational status of the relays whilst in
RUN mode, as follows:
LED 1
LED 2
RUN MODE

Program Mode
This mode is used to set up the Flow Monitor or change information already
set. You must use either the on-board keypad (standard) or alternatively the
unit can be set up with a Handheld Calibrator (optional), which must be
connected to the Flow Monitor via the RS 232 Serial Interface.
Entering a value for each of the parameters that are relevant to your
application provides all the programming information.
How to Access Program Mode
To enter program mode, you simply enter the passcode, via the keypad,
followed by the ENTER key. The default passcode is 1997, so you would
press the following:
There are two means of editing parameters, directly or using the menu
system. Each is now described.
Using the Menu System
The menu system has been designed to make the changing of parameters
very simple. There are two levels of menu: Main Menu and Sub Menu.
On the display there is a line of text that shows the menu system. Pressing
the arrow keys scrolls the display between the top-level menu items, (as
shown below, starting at Quick Setup).

As you press the cursor keys to scroll left and right between these, you can
press ENTER at any time to select it and take you to the sub-menu. Each of
these options, along with their sub-menus is described in Chapter 5,
Parameter Guide. When you move down into the sub-menu, you can scroll
round using the arrow keys, press ENTER to go to the required section of
parameters.
Once you have reached the relevant section, scroll through the parameters,
and enter the necessary information. To enter the information, use the
numeric keys and press ENTER and you will see the message “Saved!”. If you
press CANCEL, then no change will be made, and the message
“Unchanged!!” will be displayed.
When you have finished, press CANCEL to go back to the previous level.
When you have reached the top level, then the Flow Monitor will ask for
confirmation before allowing you to go back into run mode. This is done by
pressing ENTER at the display prompt.
Directly Editing Parameters
If you already know the number of the parameter, that you wish to look at or
edit, simply type the number in at any time while you are in the menu
system. Thus, if you are in either the menu or sub-menu level by pressing a
numeric key, you can enter the parameter number directly and jump straight
there. You cannot type a parameter number whilst at parameter level, only at
one of the two menu levels.
When you are at a parameter, the text line rotates automatically displaying
the parameter name, number, the applicable units and the maximum and
minimum figure you can enter. The top line shows the value you are setting.
Once you have accessed a parameter, you can either just look at it, or
change it.
Once a parameter has been changed, press ENTER and you will see the
message “Saved!”. If you press CANCEL, then no change will be made, and
the message “Unchanged!!” will be displayed.
TIP: You can jump straight to the last parameter you edited, by
pressing the +/- key when you first enter program mode.
Page 24
FLOWMONITOR INSTRUCTION MANUAL
24
Test Mode
Test mode is used to simulate the application and confirm that all
parameters and relay setpoints have been entered as expected. During
simulation, there is a choice of whether the relays will change state (hard
simulation) or not (soft simulation), but the LED’s will always change state to
indicate that the relay setpoints have been activated, and the mA output will
change. If you wish to test the logic of the system that the relays are
connected to then select hard simulation, but if you do not want to
change the relay state, then select a soft simulation.
There are two simulation modes, automatic and manual. Automatic
simulation will move the velocity up and down between minimum velocity
and maximum velocity, whereas manual simulation will allow you to move
the velocity up and down using the arrow keys.
To enter simulation, first go to program mode. Then, using the menu
system, select menu item ‘Test’ then sub-menu item ‘Simulation’. Simply
change the value of the parameter P980 to one of the following:
1 = Manual soft simulation
2 = Automatic soft simulation
3 = Manual hard simulation
4 = Automatic hard simulation
To return to program mode, press CANCEL and test mode will end.
When in manual simulation, by default test mode will move the flow or
velocity by 0.25 steps. Altering the increment (P981) will change this value.
In automatic mode, the rate at which the velocity moves up and down is set
by the increment (P981), and the rate (P982) in minutes, which can be
changed to make the flow or velocity move up and down faster. E.g. if
increment (P981) is set for 0.25 and rate (P982) is set to 1 min then the
flow or velocity will increase or decrease at a rate of 0.25/min. To make the
simulated flow or velocity move slower, decrease the value in increment
(P981) or increase the value in rate (P982). To make the simulated flow or
velocity move faster, increase the value in increment (P981) or decrease the
value in rate (P982).

Using the RS232 Serial Interface
The RS232 serial interface is used to program the Flow Monitor and obtain
information using a PC or other computer equipment. To do so, the settings
for control are as follows: baud rate 19200, 8 data bits, no parity, 1 stop.
The device should be connected to the RS232 Interface via the RJ11
connector as shown in Chapter 2 Installation.
Parameter Defaults
Factory Defaults
The date (P931) and time (P932) in the Flow Monitor were set at the factory,
but may need checking or amending if, for example the application is in a
time zone other than GMT, see Chapter 5 Parameter Guide for full details.
Once you are satisfied with the installation, you can proceed with
programming for the intended application. It is sensible to program all of
the required parameters at the same time. The system will be then set-up.
Important Notice
When first installing the Flow Monitor, or subsequently moving or using the
unit on a new application, before proceeding to program the unit for its
intended application it is recommended that you ensure that all parameters
are at their default values by completing a Factory Default (P930).

its default, by pressing the hot key, whilst in program mode.
Application Parameters
Operation
P102 Mag Threshold
This parameter sets the sensitivity of FlowPulse sensor. The Mag Threshold
value sets the required level of signal above the minimum signal before the
FlowPulse decides it is seeing flow. The default is set at 1600 which means
that the FlowPulse must see a signal strength of at least 16 above the
minimum signal before it decides there is flow.
Default = 1600
P104 Damping
This parameter sets the damping of the FlowPulse unit. The value of the
damping sets the amount of flow readings it uses to create an average flow.
The default is set to 24, meaning the average of 24 readings will be used as
the flow value.
Default = 24
P105 Averaging
This is the number of averaging to perform on the reading – this is
independent of the damping process.
Reducing this will increase flow sampling rate at the expense of
measurement stability.
Default = 6
P108 Cal Factor
This parameter sets the calibration factor for the FlowPulse unit in
percentage. The FlowPulse is designed to give a repeatable flow value.
However, if the value being read by the FlowPulse does not meet the flow
value that is expected the Cal Factor can be used to modify the output.
Default = 100%

P110 Pipe Diameter
This parameter sets the internal pipe diameter of the pipe that the FlowPulse
is connected to.
Default = 0.1 metre
P111 Noise Adapt Threshold
This parameter defines the difference between the minimum value of the
trace and the normal floor before a trace is considered to have a raised
noise floor due to noise.
Default = 800
P113 Step Response
The step response allows Flow Pulse to temporarily bypass damping and
track any sudden change in flow commonly encountered during the
beginning and end of a pumping cycles.
OPTION
DESCRIPTION
0 = Off
No Effect
1 = On (Default)
Step Response is enabled
P115 StepResThres
The Step Response Threshold is the change in flow required for the normal
damping to be bypassed. The range of the step response threshold is:
Min = 22, Max = 426 Default = 60
426 relates to the ‘Flow High’ value.
The higher the step response threshold, the larger the jump in flow needs to
be before damping is skipped.
P120 Minimum Flow Cut-off
This parameter multiplies the units of flow by 23 on the horizontal axis of the
flow trace. E.g. if the parameter is set to 2300, then the corresponding flow
index would be 100. The Flow Pulse via the Flow Monitor will not report any
flow unless the flow indicator exceeds 100 on the flow index.
Default = 740
Page 35
PULSAR MEASUREMENT
35
P121 Step Limit
This parameter sets the limit on any sudden change in the flow reading
between measurements, even while damping is being bypassed by step
response.
P128 TrackThrAdd
This is only activated when noise floor is raised, such that the noise floor is
more than P111 away from the normal floor without flow. This causes the
flow to be tracked at a lower flow index so that compensation can be
applied.
Min = 20, Max = 2000 Default = 400
P134 Particle Density
This parameter is used to set the type of material being measured in the
pipe that the FlowPulse is attached to.

(P830) Output Range) and 100% of the operational span (20mA), but you
may wish to have the output represent a section of the operational span. For
example, the application has an operational span of 6 m/s but output is to
represent 0m/s (0 or 4mA dependant on (P830) Output Range) to a level
of 5 m/s (20mA). If so P834 (Low Setpoint) should be set to 0.00 m/s and

for example accept less than 2mA, yet you want to use the 0-20mA range.
Default = 0.00mA
P837 Output High Limit
This parameter sets the highest level that the mA output will rise to, the
default is 20 mA, but you can override this if the device you connect to
cannot for example accept more than 18 mA, yet you want to use the 0-20
mA range. Default = 20.00mA

Trim
P838 Output Low Trim
If the device you are connected to is not calibrated, and not showing the
correct low value (reading), then you can trim it using this parameter. You

correct high value (reading), then you can trim it using this parameter. You
can either type in the offset directly or use the arrow keys to move the
output up and down until you get the expected result (reading) on the
device that is connected.
Failsafe
P840 Output Fail-safe Mode
This parameter determines what happens to the output in the event of the
unit going into fail-safe mode. The default is to do the same as the system
fail-safe (P808), but this can be overridden to force the output to an
independent fail-safe mode as follows:
OPTION

Test Parameters
Simulation
P980 Simulate
Test mode is used to simulate the application and confirm that all
parameters and relay setpoints have been entered as expected. During
simulation, there is a choice of whether the relays will change state (hard
simulation) or not (soft simulation), but the LED’s will always switch
according to how the relays have been programmed, and the output will
change accordingly. If you want to test the logic of the system that the
relays are connected to then select a hard simulation, but if you don’t want
to change the relay state, then select a soft simulation.
There are two simulation modes, automatic and manual. Automatic
simulation will move the velocity up and down between minimum and
maximum velocity and activate the relay and/or corresponding LED at the
programmed setpoints, if you wish to change the direction of the velocity
movement at any time this can be done by using the arrow keys. In manual
simulation, using the arrow keys will allow you to move the velocity up and
down as required. The choices for you to enter are as follows.
1. Manual soft simulation
2. Automatic soft simulation
3. Manual hard simulation
4. Automatic hard simulation
To return to program mode, press ‘CANCEL’ and test mode will end.
P981 Increment
By default, simulation mode will move by 0.25 steps in manual simulation
and by 0.25/min in automatic simulation. Altering the increment can change
this value.
P982 Rate
In automatic mode, the rate at which the measurement will move up and
down is determined by the Increment (P981) and the time, Rate (P982)
which can be changed as required. To increase the rate at which the
measurement moves increase the Increment (P981) or decrease the Rate
(P982). To decrease the rate at which the measurement moves decrease the
Increment (P981) or increase the Rate (P982).

P983 Test Max
This parameter determines the maximum of the simulated measurement
values.
Default = 1000
P984 Test Min
This parameter determines the minimum of the simulated measurement
values.
Default = 0
Hardware
P991 Hard Test
When this parameter is selected, the unit will test the following in turn:
• LED’s. Watch them change colour as shown on the display and
press ENTER if they operate as shown.
• Relays. Press a numeric key, corresponding to the number of the
relay you wish to test, and the relay will change state each time the
key is pressed. If you press any other key, other than a valid relay
number, then the test will end.
• Segments. All the segments on the LCD are lit up so you can see if
they all work. Press ENTER to end the test.
• Keys. You should press each key to confirm it works, with a counter
showing how many more keys remain un-pressed. Be sure to press
the CANCEL key last as this will show if all keys were pressed or
not. If they were not, then an error message is displayed.
P992 Output Test
This parameter will allow you to force a specified current on to the output to
test any equipment that it is connected to. The figure you enter will be
generated by the output.
P993 Relay Test
Press a numeric key corresponding to the number of the relay you wish to
test, and the relay will change state each time the key is pressed. If you press
any other key, other than a valid relay number, then the test will end.

CHAPTER 5 TROUBLESHOOTING
This section describes many common symptoms, with suggestions as to
what to do. If the issue persists, please contact your local Pulsar distributor.
SYMPTOM
WHAT TO DO
“No Sensor” message displayed.
Check power supply. Check wiring to
FlowPulse sensor.
“P102 Fail” message is displayed
Check that the correct Device Address
(Modbus ID) for the FlowPulse has been
entered into P142 of the Flow Monitor.
This can be checked by connecting the
FlowPulse to FlowPulse PC to check the ID
set on the sensor.
Current velocity reads zero, but you
know there is flow movement.
Ensure FlowPulse sensor is mounted
correctly and in accordance with chapter 2.
LED’s change colour at relevant
relay switch points but relays do
not change state.
Check supply to unit and ensure voltage
selector set to correct position.
