1. Description
FlowVis Digital is the latest and most signicant upgrade to date to the renowned FlowVis family. By adding Digital functionality
to the already unrivaled accuracy and exibility of FlowVis ow meters, users will now experience even greater functionality, ease
of use, and precision. Unique features such as Pool Turnover Rate and an ability to set ow rate alarms, will further enhance the
industry’s most respected ow meter.
FlowVis Digital employs a patented electronic design to accurately measure the ow rate. A remote digital display, housed in a
NEMA 4X corrosion proof enclosure, displays the ow rate in both a numeric value as well as in a bar-graph format.
Even with the ability to install FlowVis in tight spaces and with almost zero straight pipe requirements, it can sometimes be dicult
to install the device in a location that makes it easy to read. FlowVis Digital solves this problem by allowing you to install a Digital
readout in a user accessible location.
In addition to greater installation exibility, the Digital upgrade will also eliminate the possibility of experiencing a parallax error
issue when reading the standard FlowVis.
Note: Parallax error can be caused by not looking at the FlowVis scale squarely – akin to a passenger in a car looking at the
speedometer and seeing a dierent reading to the driver. Additional details relating to this, can be found in the FlowVis Operating
Manual.
Using the ‘Advanced Setup’ features, FlowVis Digital can be interfaced with other systems such as heaters, chemical feeders and
UV units, so that they will only operate above a user-dened ow rate. When using this option, it will be necessary to include the
Auxiliary Interface Unit with your purchase.
FlowVis Digital also includes a 4-20 mA output that can be interfaced to Variable Frequency Drives, such as H2ow’s
Eco-Flow in order to achieve constant ow control.
2. Compatibility
FlowVis Digital is designed to be included (as an option) with any new FlowVis installation. Alternatively, it can be retrotted to
an existing FlowVis – regardless of the size or model. For retrot installations however, it is important to take careful note of
sections 6.1 and 6.2 of this manual.
3
a) Electrical: FlowVis Digital utilizes a 100-240VAC to 12VDC power supply that needs to be plugged into a
standard receptacle. The power supply cord should be rmly inserted into the receptacle, and a plug restraining clamp
should be added, if any of the FlowVis Digital’s outputs are being interfaced to other equipment such as VFD’s, Heaters,
Chemical Feeders or any safety related equipment.
b) Mechanical: The FlowVis Digital sensor housing should only be secured to the FlowVis lid using the two extra long 1”
(25mm) stainless steel Phillips head screws provided.
3. Safety information
WARNING
ALL CONNECTIONS MUST BE MADE BY A QUALIFIED ELECTRICIAN. ELECTRIC SHOCK CAN CAUSE
SERIOUS INJURY OR EVEN DEATH.
IMPORTANT INSTALLATION NOTE Installers should read the section ‘Advanced Setup’ prior to
installation. This section details the need for a Windows-PC with internet connection to complete an advanced setup.

6. Pre-installation
This section only applies to FlowVis models that are 2.5” and below OR, FV-3 (DN80) and FV-4 (DN100) that were provided prior to
November 2020. This section covers two scenarios for installing the FlowVis Digital system:
a) Install FlowVis Digital to a new OR existing FlowVis unit for 1.5”/DN40, 2”/DN50, or 2.5”/DN65 pipe. If this section applies
to you, please refer to Installation section 6.1 before proceeding to Installation section 6.3.
b) Install FlowVis Digital to a 3”/DN80 or 4”/DN100 FlowVis that was manufactured before November 2020. If this section
applies to you, please refer to Installation section 6.2 before proceeding to Installation section 6.3. If your FlowVis
3”/DN80 or 4”/DN100 was manufactured after March 2020, please proceed directly to Installation section 6.3.
Note: To conrm the manufacturing date of your FV-3 (DN80) or FV-4 (DN100), look at the 2-digit code on the side of the FlowVis lid
and conrm that it is equal to or greater (later) than HT18. For example HT18 is greater (later) than HT17. If the code on your FlowVis
lid is less than (before) HT18, a new, compatible lid assembly will be required. Please contact H2ow for assistance in determining
the appropriate lid assembly for your installation.

7. Installation
6.1. Replacing the apper & indicator assembly in
1.5”(DN40) 2” (DN50) and 2.5”(DN65) installations
For the FlowVis Digital (FV-D) to function on FlowVis
models DN40, DN50, and DN65, it will be necessary to
replace the Flapper and its attached red indicator with
the one provided in the FlowVis digital (FV-D ) packing
box (see Fig.1.4 on page 4) - regardless of whether the
FlowVis unit itself is new or already installed. This is a
simple procedure that will take less than 2 minutes;
however, it is important to reassemble the unit exactly
as shown below.
Spring legs location tabs
Procedure:
1. Release each of the two spring legs from the location tabs - this will
remove the tension from the spring. See Fig.2.3 above.
2. Slide the Hasteloy pivot pin to completely remove it from the lid.
3. Discard the existing gray Flapper with its attached red indicator.
4. Pay attention to the orientation of the spring when reassembling the unit.
5. Install the new Flapper and Indicator following a reversal of the
disassembly procedure. Note, you may nd it easier to place the spring’s
legs over their location tabs before sliding the pin.

Installation cont.
6.2. Installing FlowVis Digital to an existing 3”(DN80) or 4” (DN100) FlowVis
1. Remove the screws from the existing lid of the FlowVis unit and remove the lid
assembly.
2. It is not uncommon for the FlowVis lid to be retained by a vacuum
suction after the 8 screws have been removed. Under no circumstances
should you try to leverage the lid o with a screwdriver or similar
device. Instead, momentarily open a valve that is either upstream or
downstream to release the vacuum.
3. Ensure that the new lid assembly has a code on the side of the lid that
is equal to or greater than HT16. For example HT16 is greater (later) than HT15.
4. Ensure that the o-ring on the underside of the new lid assembly is
undamaged, lubricated with silicone (such as Boss 820), and is in-place
without twists.
5. Carefully lower the lid onto the Tee, making sure that the o-ring stays in
place. Also make sure that its orientation is correct; the top of the FlowVis scale
should be toward the direction of ow.
6. Referring to Fig.2.5 (right), identify the required side of the FlowVis to mount
the FlowVis sensor, ensuring that the sensor is fully seated and the screw holes
line-up with those on the FlowVis lid assembly.
7. Place 6 of the 8 FlowVis screws in the lid assembly, and use the 2 longer screws
provided with your FlowVis Digital (Fig.1.3 on page 4) in the holes for the
sensor. Do not tighten.
8. Using a hand Phillips-head screwdriver, slowly tighten the screws in a diagonal
pattern, per the diagonal sequence shown in Fig.2.6. Do not fully tighten one
screw before proceeding to the next, i.e., pull them down slowly multiple
times to avoid stressing and cracking the lid. Screws should be tightened to a
nal torque of 25 in./lbs. or 2.8 Nm. Disclaimer: Under no circumstances should
the screws in the FlowVis lid assembly or sensor be tightened with an electric
screwdriver in the ‘drill’ setting. This can result in a cracked lid or sensor and will
void the product warranty.
9. Proceed to section 6.3 to complete the installation of your FlowVis Digital.

6.4. Sensor/blue light is ashing
A blue LED is visible when looking at the sensor. A ashing blue LED indicates that the FlowVis does not have a magnet installed.
All FlowVis models that are 3”(DN80) and larger that were manufactured after November 2020 had this magnet installed. If
your application involves a unit that is ≥ 3” (DN80), and the sensor light is ashing, it is apparent that your FlowVis unit was
manufactured before this date. Please contact Dryden Aqua to nd a solution. If your FlowVis model is for a 2.5”(DN65) or smaller,
and the blue sensor light is ashing, please install the replacement apper/indicator that was included in the FlowVis Digital
shipping box (see section 6.1 of this document).
Installation cont.
6.3 Installing FlowVis Digital to a new or existing FlowVis
PLEASE NOTE: If you are installing FlowVis Digital to either, a) an existing 1.5”(DN40), 2x2.5”(DN50/65), please refer to
section 6.1, or b) an FV-3(DN80 or FV-4(DN-100) that was manufactured before November 2020, please refer to section 6.2 of
this manual before proceeding with section 6.3.
1. Check the contents of your FlowVis Digital box to ensure that they comply with the components shown on page 4
of this document
2. Unless previously done in section 6.2, remove the two FlowVis lid screws that will align with the hole mounting tabs
for the sensor (refer to Fig.2.5 on pg. 7).
3. Mount the sensor, ensuring that it is fully seated and the screw holes line-up with those on the FlowVis lid assembly (see
Fig.2.5).
4. Place the 2 extended screws provided with your FlowVis Digital (Fig.1.3 on page 4) in the holes for the sensor and
using a hand Phillips-head screwdriver, slowly tighten the screws. Do not fully tighten either screw before proceeding
to the next, i.e., pull them down slowly, multiple times to avoid stressing and cracking the sensor. Screws should be
tighteneed to a nal torque of 25 in./lbs. or 2.8 Nm. Disclaimer: Under no circumstances should the screws in the
FlowVis lid assembly or sensor be tightened with an electric screwdriver in the‘drill’setting. This can result in a
cracked lid or sensor, and will invalidate the product warranty.
5. Mount the FlowVis Digital Display enclosure in a location that is: a) convenient for viewing, b) close enough to the
FlowVis ow meter for the sensor cable length (including any extension cables you may have purchased), and c)
close enough to a 100-240VAC receptacle to allow the power supply to connect. Note: The power supply output
(12VDC) cable has a total length of 10 feet / 3M, but can be extended up to a total length of 24 feet / 8M. It is essential that
its polarity is maintained. Good electrical practices should be used when extending this cable.
6. f ) Connect the Power Supply low voltage (12VDC) output to the Display (see wiring diagrams on pages 9 & 10).
7. g) Connect the Sensor to the display using either the standard-length cables provided or the extension cable (if
purchased).
8. Disclaimer: The sensor-to-display cables MUST NOT be cut or spliced in any way. Doing so will invalidate the
FlowVis Digital product warranty. If these cables are longer than needed, we suggest coiling the excess cable
and tying with a zip-tie.
9. h) Plug in the Power Supply and ensure that the Digital Display illuminates and the blue light on the sensor is on (not
ashing). If the blue light is ashing, please refer to section 6.4.
10. i) If being used, connect 4-20 mA output to external equipment such as a VFD (see Fig.2.9).
11. j) If being used, connect the alarm relay (see Fig.3.1).
12. k) Proceed to the Programming section.

11. Operation
After setting the DIP Switches to reect the FlowVis model and Pipe Size employed in your application, the FlowVis Digital
is ready to use. No calibration or further settings are required. However, by default, the FlowVis Digital readout will display
the ow rate in US GPM and the Turnover Rate will show --- (indicating that this function is not activated). If you would like to
change the unit of measurement from US GPM to either LPM or M/hr, and /or activate the pool Turnover Rate function, then it
will be necessary to access these functions as described in the Advanced Setup section.
12. Advanced setup
Although FlowVis Digital will function as a ow meter without additional steps, there are several very useful features that can
be accessed via the‘advanced setup’ procedures. These features comprise:
• Display of the pool turnover rate
• Changing the display’s appearance at a user-dened ow rate
• Programming an (optional) auxiliary relay to operate external equipment such as a Heater or Chemical Feed System,
which will only operate at user dened ow rates
Programming the advanced features will require a Windows-based laptop PC. The initial step is to download the Advanced
Panel Display Software from the internet, we recommend that this be done in an oce environment rather than the pool
equipment room. Note: there is no requirement to connect the laptop to the Display during this initial step.
The laptop PC will require the following:
• Running either a Windows 7, 8, or 10 operating system, using either a 32 or 64-bit conguration
• Microsoft .NET Framework (if you don’t have this, it can be downloaded from www.microsoft.com/net)
• A spare USB 2.0 port (for later connection to the Display)
• An internet connection

13
Advanced setup cont.
Step 2 - Programming the advanced features of the FlowVis Digital Display
With the Congurator program still open, connect the Display to your PC using the Type A to Type B cable that was delivered
with your FlowVis Digital (Fig 1.5).
The FlowVis Digital screen should display the text ‘US.b’, and the Congurator should now look like Fig.3.6, below. Click on
the ‘Congure APM’ button.
Fig 3.6
Step 1 - Download and install the‘Advanced Panel Display’ Congurator Software:
Launch an internet browser page and go to www.h2ow.net/owvis-digital-ow-meter and locate the ‘Congurator’ section,
either by clicking on the tab titled ‘Congurator’ in the page header, or by scrolling down the page to this section.
Click on the ‘Congurator Download’ button. When the Congurator has nished
downloading, open the le, either from your Downloads folder, or from the bar at
the bottom of your browser. Follow the prompts provided by the Setup Wizard and
when asked, click on ‘Save As’. Save the le to your preferred location. The default
le name will be ‘APM Congurator’.
After downloading the le, double-click on the icon labelled ‘APM Congurator’.
You should then see an image on your desktop which resembles Fig 3.5 (right).
Click on the ‘Updates’tab and make sure that the‘Automatic Updates’option is
checked. If ‘Automatic Updates’was un-checked, please check this, and then close
the program and re-launch. If new updates are available, they will be automatically
downloaded and saved to your PC.
The Congurator program has now been successfully installed and your laptop is
ready to connect to the FlowVis Display.

Advanced setup cont.
You can change this value to that desired for your application, and you can also determine the condition that you wish it to
operate, e.g., above or below the programmed value, between or outside the programmed values. Note that when either of
these latter two options are selected, a second value window will appear.
Beneath this you will see an option to select the relay’s sensitivity in detecting the programmed condition at which you wish
it to activate; the default is set to‘low’. It is recommended that you do not adjust this unless you need the relay to operate
immediately when the ow rate hits the programmed level. Please note, however, that the equipment connected to the relay
may experience rapid turning on and o when the ow rate is turbulent and is close to the programmed alarm value.
Finally, you may also wish to change the appearance of the Display when the Alarm condition is met. For example, if you
wanted to make the screen ash red when the ow rate is above a certain value such as a high ow rate, you can achieve
this by checking the ‘Change Backlight’ box and selecting the desired appearance.
When all changes have been made, it is essential that you click on ‘APM’ in the menu at the top of the screen, and then
click on the dropdown option‘Write Conguration to APM’.
Before disconnecting the Type A to Type B cable between your PC and the Display, you may wish to save your conguration
settings. To do so, click on ‘File’ at the top-left of the Congurator screen, and then click on ‘Save Conguration File’ from the
dropdown menu. In the ‘Save As’ dialog box, navigate to the location that you wish to save the le, and give it a Filename
before clicking on the ‘Save’ button.
Fig 3.7
You should now see a screen that looks like the one below (Fig. 3.7):
In this screen, you can program:
• The unit of measurement in either
US GPM (default), LPM, or M3/h
• If being installed to a swimming pool,
then the turnover rate by inserting
the volume of your pool
Please do not change any other values.
‘Alarm 2’has been designated to the
Digital (Open Collector) output that can
be connected to control the optional
Auxiliary Relay kit discussed in section
13 of this manual. In the right-hand side
of this screen, you can program the
condition that you wish the relay to
activate. As can be seen from the default
values, it will operate when the ow rate
is above 25 GPM.

15
13. Auxiliary relay (optional kit)
The Auxiliary Relay option is a valuable feature that allows the FlowVis Digital user to control external devices such as Heater
and Chemical Feeders at user-dened ow rates. For example, you may want to control the Chemical Feeder to operate only
above 20 GPM. Setting this value is discussed in Section 12.
The Auxiliary Relay option kit installs into the rear of the FlowVis Digital Display enclosure and comprises the following items:
Qty. Item
1 Auxiliary Relay with 12 VDC coil and 2 sets of souble pole / double throw dry contacts
1 Set of relay coil wires
1 Cable zip ties (2) with (1) adhesive pad
6 Crimp style Cable Spades

Auxiliary relay (optional kit) cont.
Installation (external)
The Auxiliary Relay comprises two sets of double pole / double throw dry contacts. Both sets of contacts will operate at
the same programmed ow rate as set in the ‘Advanced Setup’section on page 14. Each of the two sets of contacts has
a normally open and a normally closed relay. The ‘normal state’is the condition that the contacts are in before they are
activated when the coil is energized by the programming value. Please refer to the Auxiliary Relay Connection Diagram (Fig.
3.0) on page 10.
Using the cable spade connectors provided, connect the external wiring to the required Auxiliary Relay outputs. For example,
if the Heater requires a contact closure to operate, connect the heater enabled circuit to either terminals 4 and 2, or 8 and
6. Both of these are normally open contacts that will close when the relay coil is energized by the setting applied in the
‘Advanced Setup’ section on page 14.
14. Display features
The FlowVis Digital Display comprises certain standard features as well as user-dened parameters / adjustments. Standard
features include a Digital and Bar Graph reading of the measured ow rate. The user has the option to program the Unit
of Measurement to be displayed in either US GPM (default), LPM or M3/hour. The patent pending feature that displays the
Turnover Rate is activated by the user during programming. The Display’s format can also be programmed by the user to
change its appearance under prescribed conditions, e.g., ash above or below a certain ow rate. Refer to the ‘Advanced
Setup’ section for more information on how to take advantage of this functionality.

Observation Solution
Digital Display not
illuminated (continued
from previous page)
• If the blue light is ashing, the sensor has not detected a magnet in the FlowVis indicator
arm. Contact H2ow for further assistance.
• Is this a retrot to an existing FlowVis? If yes, did you install a new lid assembly that is
‘Digital’ compatible? If no...
• Contact H2ow for further guidance
Digital Display is reading
a ow rate that is
signicantly dierent to
the FlowVis
• Check that the DIP switch settings applied in ‘Programming’section, correcly related to
the FlowVis model being used. If applied correctly, please contact Dryden Aqua for further
guidance.
Turnover rate appears to
be inaccurate
• The turnover rate is calculated by the programmed pool volume, divided by the ow
rate. Perform a manual calculation as follows: (Pool Volume ÷ Flow Rate from FlowVis) ÷
60 = Turnover rate in hours. If this number is different to the value shown on the FlowVis
Display, reconnect your laptop and check that the pool volume has been accurately
entered.
External equipment such
as a Heater or Chemical
Feeder, that is being
controlled by the Auxiliary
Output, is turning on and
o erratically
• Reconnect laptop PC and check that the Sensitivity Level has been set to‘Low’. If yes...
• Check the flow rate reading is well above (or below) the set level programmed to turn
on (or off) the Auxiliary Output. If the actual flow rate is close to the set value and there is
turbulence causing the flow rate to be erratic, consider adjusting the set point value.
Display is showing
the wrong unit of
measurement
• Connect your laptop and check to see the required Unit of Measurement (US GPM, LPM

Denition
H2ow Controls, Inc., warrants the FlowVis® product for 3-years from its date of supply from H2ow Controls, Inc. or its
stocking Distributor. In the event that the product experiences a premature failure due to defective workmanship or materials,
H2ow will, at its discretion, replace either the failed component(s) or the complete FlowVis Digital unit. H2ow shall not be
responsible for third-party labor or any consequential losses. Damage caused by improper installation, misuse or exposure to
corrosive chemicals, will not be covered by this warranty.
Eligibility
This warranty extends to the original purchaser only or to the end-user client of an H2ow Controls Inc. authorized aliate.
How to obtain service
To obtain service under the terms of this warranty, the customer is required to notify H2ow Controls Inc. before the expiration
of the warranty period and to return the item in accordance with H2ow Controls Inc’s product return policy. Any product
returned for warranty repair must be accompanied by a full fault report specifying the symptoms and the conditions under
which the fault occurs. Should H2ow Controls Inc. incur additional cost as a result of a failure to complete the appropriate
paperwork, an administrative charge may be levied.
Exclusions
This warranty shall not apply to any defect, failure or damage caused by improper use or improper or inadequate care.
H2ow Controls Inc. shall not be obligated to provide service under this warranty if:
a) damage has been caused by a failure to make a full and proper inspection of the product (as described by the
documentation enclosed with the product at the time of shipment) on initial receipt of the product following shipment;
b) damage has been caused by the attempts of individuals, other than H2ow Controls Inc. sta to repair or service the
product;
c) damage has been caused by the improper use of the product, including but not limited to, the cracking or breakage of
a FlowVis Digital sensor or FlowVis lid due to the over-tightening of lid screws, damage to the FlowVis Digital LCD display
screen due to misuse or excessive exposure to chemicals, the splicing or cutting of cables or wires unless explicitly instructed
to do so during the installation process, or the installation of an indoor-rated FlowVis Digital enclosure in an outdoor
environment.
Charges
Under cover of this warranty, H2ow Controls Inc. will pay the carriage and insurance charges for the
shipment of defective product back to H2ow Controls Inc. and for its return to the client’s original site
of dispatch except when:
a) H2ow Controls Inc’s product return policy has not been followed.
b) product failure is caused by any of the exclusions described at paragraph 4 above, when the customer will be liable for the
full cost of the repair (parts and labor) plus all carriage and insurance costs to and from H2ow Controls Inc’s premises.
c) the product is damaged in transit and a contributory cause is inadequate packaging. It is the customer’s responsibility
to ensure that the packaging used to return equipment to H2ow Controls Inc. is the same, or has equivalent protective
qualities, to that used to ship the product to the customer in the rst instance. Any damage resulting from the use of
inadequate packaging will nullify H2ow Controls Inc’s obligations under this warranty.
Should the customer’s product be damaged in transit following a repair at H2ow Controls Inc’s site, a
full photographic record of the damage must be obtained (packaging and the product) to support any claim for recompense.
Failure to present this evidence may limit H2ow Controls Inc’s obligations under this warranty.
THIS WARRANTY IS GIVEN BY H2FLOW CONTROLS INC. IN LIEU OF ANY OTHER WARRANTIES, EXPRESSED OR
IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY, NON INFRINGEMENT
OR FITNESS FOR A PARTICULAR PURPOSE. H2FLOW CONTROLS INC SHALL NOT BE LIABLE FOR ANY SPECIAL,
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES. WE SPECIFICALLY DISCLAIM ANY AND
ALL WARRANTIES TO CUSTOMERS OF THE CUSTOMER. THE CUSTOMER’S SOLE REMEDY FOR ANY BREACH
