I bought these favorable electronic flow switch because my
previous experience were that expensive (up to 130,00 Stk) not lasted longer.
I must say that the switches are installed with me in a well shaft and have to contend with condensation.
Previous durability of switches were a maximum of 3 years (I've tried so far 4 different models)
The switch makes a qualitatively good impression.
As with many models much plastic was processed. That does not affect the durability.
Installation was straightforward and the unit does its work very neat.
The key will be how long it works flawlessly.
So far, I have to say: good equipment at an unbeatable price.
As I said I have the most expensive equipment Grundfos had etc.
Ironically, the Grundfos has given up the ghost during the warranty period
but "condensation" in the housing is not covered by the Garanie, therefore no refund .....
Since I can from these switches buy 4 pcs for the price of a Grundfos pressure switch. ;-)
At the moment I can only recommend buying.
