Hi,

I have purchased an Flowsensor 5000 l/h last week.

Does the flowsensor need to be calibrated?

I'm using a Tunze Silence 1073.05 with the flowsensor, according to Tunze this pump should have a maximum of 3000 l/h, according to the flowsensor the flow is around 1060 l/h. I have tested it with two identical Tunze pumps, both have the same amount of flow on the sensor when running on maximum speed.

The height of the tubing is only 50 cm, so this couldn't be an issue.



Are both the Tunze pumps failing, or is the reading not right?



Regards,
Jasper
