The tank alarm is mounted at the ventilation hole in the oil tank with the tank pipe downward into the oil tank. When the filling of the oil starts, the tank alarm whistles. This whistle sound will change, when the oil reaches the pipe and stops, when the oil reaches the the hole in the side. The cross bar indside the house prevents the in reaching too up into the alarm, even by a very high filling pressure.
