Our liquid level senders are level indicating devices compatible with all the petrol and water level gauges available on the market.
They are fuel, sea-water and acid resistant because they are made of the highest stainless steel AISI 316. They are perfectly watertight and have a flange with holes that allows a perfect fitting on the tank.
The sender cables must be connected to the measuring terminals of the indicating instruments, as explained in the user's manuals of the later.
