2. Installation
•The Atrato must be installed in a positive pressure system. Ensure that
there is sufficient back pressure on the flowmeter to keep any gas in
solution.
Back Pressure >500mbar plus two times the liquid vapour pressure
backpressure
•Locate the flowmeter in a sheltered position away from falling water.
•Care must be taken to ensure that the end fittings on the meter are not
stressed during use. Ideally, flexible tubes should be used.
•Ideally the meter should be installed with straight lengths of tube either
side for a distance of 10 pipe diameters upstream and 5 downstream.
•Install the device well away from valves, regulators, bends and other
components that could cause excessive turbulence on the fluid
entering or leaving the meter.
•If necessary, use spacer blocks and mounting clips to raise the pipe
work centre line 58mm above the surface.
•It is good practice to use upstream and downstream isolating full bore
ball valves to facilitate easy meter installation or removal.
•If push-in 3/8” John Guest fittings are used, clip the pipes to the
mounting surface 300mm upstream and 150 downstream.
•If there is any chance of air passing through the system, mount the
Atrato in a vertical pipe with the flow in an upward direction. Otherwise,
air can remain trapped in the meter and affect its performance.
•The Atrato is not recommended for pulsating flow. Any pulsations must
be damped to less than 10Hz to prevent aliasing of measurement.

8 Titan Enterprises Ltd ©2021 Atrato_Instruction_Manual_0322
®
Using suitable fixings, mount the connection box onto a rigid surface with the cable entry
preferably at the bottom.

9 Titan Enterprises Ltd ©2021 Atrato_Instruction_Manual_0322
®
The flowmeter should be clipped into place with the terminal screws positioned at the lower
edge. Note that the rubber strip covering the terminals on the meter will not seal if water is
persistently present in this area. Ensure the meter is not pressure washed. The Atrato can
easily be dismounted by inserting a screwdriver under the mounting clip and gently unclipping
it to release the main body. The PG9 thread can be either connected to suitable flexible conduit
or may be fitted with the supplied cable gland.
Position flow meter to prevent gas lock in measurement tube

3. Electrical
WARNING:
The Atrato is designed to be powered from either USB or external DC power.
When connected to both supplies, there is potential for damage to the flow meter
from ground loops or direct shorting of any non-isolated power supplies. The user
must ensure the 0V from the USB and the negative terminal of the DC supply are not
at different voltages, by correct earthing or isolation.
The Atrato can be programmed using the USB connection via a computer.
The Atrato can operate solely on USB power via the computer or a high quality USB2 power
supply (e.g. RS 9076255 5V 5W supply), the meter display will function, as will the relay and
pulse outputs (require target power).
For full functionality, including the analog outputs, 15-24VDC external power is required.
The unit will work with systems from Windows XP onwards.
The maximum connector cable size is 2.5mm (22-14AWG); for ease of assembly we
recommend 1mm maximum. Care should be taken when terminating the wires as the
conductors should be stripped to 4 to 5mm maximum and the wire ends must be pushed fully
into the connector before tightening. These cables pass through a slot cut in the aluminium
housing. Please ensure that no bare conductors are in contact with the surface of the
connector strip prior to closing the housing.
NOTE: The Titan Interface Software allows the user to test the outputs from the flow meter.

4.3. User Settings Tab
4.3.1. Calibration Settings
Units: A drop down menu offers the choice of - Litres, ml,
gms, kg, US gallon, Imperial gallon or Custom units i.e.
blank.
Note that the Custom Units setting will be equivalent to Litres
if no modifications are made to scale factor.
Rate (units per): This is the time base for the flow rate and
has the option of Second, Minute or Hour.
Scale Factor Adjustment: This allows the user to adjust or
tune the calibration flow value if required.
Density: The flowmeter is fundamentally a volumetric device,
but a density figure can be entered here if one of the mass
units is selected. Caution must be used however, as there is
no temperature/density correction.
Cut Off: Flow values below this level will be set to zero.

18 Titan Enterprises Ltd ©2021 Atrato_Instruction_Manual_0322
®
4.3.2. Display Appearance
Decrease Total for -ve flow: The meter will not register
negative flow on its outputs unless this box is checked.
For reverse flow the rate will show a “-”sign before the rate
and the total will be reduced accordingly.
One of the transistor outputs (PNP or NPN on Pin 6 or 7)
are configurable to give a logic level when reverse flow is
detected.
Once selected, the totaliser will adjust with the negative flow
and the NPN and PNP outputs will give a pulse output in
proportion to reverse flow seen.
The analog pins will give an output if scaled appropriately.
4.3.3. LCD Options
Display Mode: Allows user to select from:
• Rate –The display will show flow rate only.
• Total –The display will show total flow only.
• Both –The display can be cycled from rate to total
using the Left-Hand button on the Atrato or the left
button in the “Flow Details” window.
The Total can be Reset at any time on the display
model by pressing the Right-Hand Button when the
Total is being displayed. Alternatively, a remote
input can be used if either pin 6 or pin 7 has been
utilised.
• Batch –By choosing batch mode the Relay can be
switched and utilized (via external equipment) to
control flow to deliver a fixed-sized ‘batch’ of fluid.
In batch mode the Left-Hand button is used to Start
or pause the batch, and the Right-Hand button is
used to Reset or ‘prime’ the system for the next
batch after the current batch has been delivered.
For more detail see Relay section.

Rate DP Position: Use the drop-down menu to choose the
default decimal point position.
Total DP Position: Use the drop-down menu to choose the
default decimal point position.
If the decimal point is set too low and the display value
exceeds the setting capacity the display will auto-range.
Viewing Filter: This prevents the display, flow switches and
analog outputs from jittering with irregularities in the flow by
averaging the results over a short amount of time. The
increments are arbitrary with the degree of damping
approximately doubling with each level. At level 5 the
display may take up to a minute to accurately reflect any
changes in the flow.
NOTE: This filter affects the Flow LCD display and the
analog outputs only.
Flow Switch alarms operate using the Filtered Flow
It has no effect on the NPN and PNP outputs which report
the unfiltered flow reading.
4.3.4. External Connections:

Pin Assignments:
The options for each PIN are: Not Used Input or Output
Each of the PIN Assignments can be configured as
either an input or an output function.
The operation to modify PIN 6 and PIN 7 is identical
within the software, with the exception of the type of
transistor pulse output:
•PIN 6 is PNP, whilst PIN 7 is a NPN type.
The options for each PIN, are:
Not Used Input or Output
NOTE: These instructions are the same for PIN 6 and PIN 7 with the exception of the transistor
wiring and operation.
For example: For PIN 7 (NPN) the idle state is switch ‘open’ which will be a high Volt output if
there is a pull-up in the circuit. PIN 6 (PNP) would be the opposite, at zero Volt.
Output
If Output is selected the output options are:
•Pulse
•Single/ Dual flow alarm
•Reverse Flow
Pulse:
Enter the number of pulses per unit volume
required. This figure can be adjusted to suit the
application and the flow range required from the
meter.
The maximum output frequency is 1000 Hz so care
must be taken to ensure that this pulse rate is not
exceeded.
Example Wiring for NPN and PNP pulse outputs:
NOTE: Best practice is to place Pull Resistor up near target device
