• Is this a retrofi t to an existing FlowVis? If yes, did you install a new lid assembly that is
‘Digital’ compatible? If no...
• Contact H2fl ow for further guidance
Digital Display is reading
a fl ow rate that is
signifi cantly diff 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 H2fl ow for further
guidance.
Turnover rate appears to
be inaccurate
• The turnover rate is calculated by the programmed pool volume, divided by the fl 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
off 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
or M
3
/hour) has been selected. Change as necessary.
