Hi All,
I am trying to make a auto topup system for a fish tank.
I have a perilstaltic pump which I have been using with a float switch for this but have now got a liquid level sensor but cant get it to work.
The basic setup is a 12v DC 300ma adaptor, the pump which is powered by what is essentially a 12v drill motor and the liquid level sensor which is rs components part number 285-778, link below to instruction leaflet.

I currently have the negative from the adaptor connected to the negative on the pump and the blue wire on the sensor. The positive from the pump then goes to the black wire on the sensor. The positive from the adaptor goes to the brown wire on the sensor.
Can someone tell me how this should be connected please?
Cheers!
