Hi - just installed my High Flow Next. Everything is working fine other than a flow reading. All other readings are fine (water temp is 22.5). Any suggestions
For testing, set your pump speed to 100%, and see if the flow reading changes. The high flow next requires a minimum flow rate of 35 L/h to show any reading.
Vertical installation can have an influence on the operating noise.
Personally, I would try the following:
Set the pump to 100% and squeeze the hose at a suitable point (or close a ball valve if one is installed,but haven't seen one, except for draining) and then suddenly release the flow again.
I would seriously rethink your tube routing, maybe move the pump up to the middle of the radiator mounting to give you more options and remove the elbow coming form the outlet of the pump as that seriously affects flow by all accounts.
"no shit lady, does it sound like i'm ordering pizza?"
yes, this things can all have as a result, that your flow is below 35-40l/h. only from this value on will the HF Next be able to detect and show a flow value.
Mine was working fine but I redid my loop and had to flip it upside down to make it fit. Now I have temp readings and rgb etc but it is registering 0.0 litres per hour flow which isn't correct. I can even hear the propeller moving.
