Page 3: Description
Even with the ability to install AcuFlow in tight spaces and with almost zero straight pipe requirements, it can sometimes be difficult to install the device in a location that makes it easy to read. AcuFlow Digital solves this problem by allowing you to install a Digital readout in a user-accessible location. -

November 2020. This section covers two scenarios for installing the AcuFlow Digital system: a) Install AcuFlow Digital to a new OR existing AcuFlow 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. -
Page 6: Installation
6.1. Replacing the fl apper & indicator assembly in 1.5” (DN40), 2” (DN50) and 2.5” (DN65) installations For the AcuFlow Digital (AF-D) to function on AcuFlow models AF-15, AF-C-M-DN40, AF-2, AF-C-M-DN50, AF-25, and AF-C-M-DN65, it will be necessary to replace the Flapper and its attached red indicator with the one provided in the AF-D packing box (see Fig.1.4 on page 4) - regardless of whether the AcuFlow unit itself is new or already installed. - Page 7 6.2. Installing AcuFlow Digital to an existing (pre- January 2021) 3”(DN80) or 4” (DN100) AcuFlow Remove the screws from the existing lid of the AcuFlow unit and remove the lid assembly. 2. It is not uncommon for the AcuFlow lid to be retained by a vacuum suction after the 8 screws have been removed.
- Page 8 Fig.2.4). 4. Place the 2 extended screws provided with your AcuFlow 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.

11. operation After setting the DIP Switches to reflect the AcuFlow model and Pipe Size employed in your application, the AcuFlow Digital is ready to use. No calibration or further settings are required. However, by default, the AcuFlow Digital readout will display the flow rate in US GPM and the Turnover Rate will show --- (indicating that this function is not activated). - Page 13 With the Configurator program still open, connect the Display to your PC using the Type A to Type B cable that was delivered with your AcuFlow Digital (Fig 1.5). The AcuFlow Digital screen should display the text ‘US.b’, and the Configurator should now look like Fig.3.5, below. Click on the ‘Configure APM’ button.
- Page 14 advanced setup cont. You should now see a screen that looks like the one below (Fig. 3.6): In this screen, you can program: • The unit of measurement in either US GPM (default), LPM, or M • If being installed to a swimming pool or tank application, then the turnover rate by inserting the volume Please do not change any other values.

13. auxiliary relay (optional kit) The Auxiliary Relay option is a valuable feature that allows the AcuFlow Digital user to control external devices such as Heater and Chemical Feeders at user-defi ned fl ow rates. For example, you may want to control the Chemical Feeder to operate only above 20 GPM. -
Page 16: Display Features
14. display features The AcuFlow Digital Display comprises certain standard features as well as user-defi ned parameters / adjustments. Standard features include a Digital and Bar Graph reading of the measured fl ow rate. The user has the option to program the Unit of Measurement to be displayed in either US GPM (default), LPM or M /hour. -
