Observation
Digital Display not
illuminated (continued
from previous page)
Digital Display is reading
a flow rate that is
significantly different to
the AcuFlow
Turnover rate appears to
be inaccurate
External equipment such
as a Heater or Chemical
Feeder, that is being
controlled by the Auxiliary
Output, is turning on and
off erratically
Display is showing

Solution
• If the blue light is flashing, the sensor has not detected a magnet in the AcuFlow indicator
arm. Contact H2flow for further assistance.
• Is this a retrofit to an existing AcuFlow? If yes, did you install a new lid assembly that is
'Digital' compatible? If no...
• Contact H2flow for further guidance
• Check that the DIP switch settings applied in 'Programming' section, correcly related to
the AcuFlow model being used. If applied correctly, please contact H2flow for further
guidance.
• The turnover rate is calculated by the programmed volume, divided by the flow rate.
Perform a manual calculation as follows: (Volume ÷ Flow Rate from AcuFlow) ÷ 60 =
Turnover rate in hours. If this number is different to the value shown on the AcuFlow
Display, reconnect your laptop and check that the volume has been accurately entered.
• 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.
• Connect your laptop and check to see the required Unit of Measurement (US GPM, LPM
or M /hour) has been selected. Change as necessary.
