If i connect the flowsensor through the Aquastream XT Ultra i get no value, it says 0,0 l/h..

And the under the " Pump and flow rate settings " the Flowsensor Active button is "pressed"

Calibration Value is 509 Impulses pr liter.
Number of measuring pulses is 8.

Anything wrong here?
If i connect i to the Aquaero it works fine.. The Calibration value there is also 509.. Is this right?

Thanks, that helped But what about the impulses? is that right? I have the "old" flowmeter..
