Digital Display not 

illuminated (continued 

from previous page)

• 

If the blue light is flashing, the sensor has not detected a magnet in the FlowVis indicator 

arm. Contact H2flow for further assistance.

• 

Is this a retrofit to an existing FlowVis? If yes, did you install a new lid assembly that is 

‘Digital’ compatible? If no...

• 

Contact H2flow for further guidance

Digital Display is reading 

a flow rate that is 

significantly different 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 flow 

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.
