GHL now offers a flow sensor designed for the ProfiLux aquarium controller. With this additional sensor ProfiLux can display the measured flow of your aquarium pump. If the flow of your pump falls below a given rate the controller will warn aquarist with an acoustic signal, send a SMS message to your phone or an email. The ProfiLux can even switch the failing pump off in extreme cases.

Two different sensors are available:

Flow 100 – 2000 l/h, nominal width DN10, 2x G1/2″ outside thread
Flow 300 – 5000 l/h, nominal width DN20, 2x G1″ outside thread
