GHL has be sporting their new product cachet as of late, with the impending release of their popular ProFilux series of aquarium controllers. We haven’t seen anything yet about the external appearance of this new device but we found something much better. It is an external level sensor that detects the water level through the glass! So throw those silly internal water sensors away, you won’t need them anymore. How does it work? Simply fix to the side of the tank and keep the inside glass clean. It uses Electro magnetic waves to detect the water surface rather than an optical sensor. These sensors have been tested on 3/4″ glass and worked. This should be available within the next two months and will work with current generation ProFilux systems.
