There is nothing like accurate monitoring of your consumption to quickly detect an anomaly, such as a leak. 3 types of gauges exist on the market.

Manual gauges (mechanical, pull cord or pneumatic): they give you the height, in centimetres, of the oil remaining in your tank.

Electronic gauges: these display the exact number of liters left in your tank. They're a little more expensive than manual gauges, but they're also much more practical and useful on a daily basis.

So-called connected or smart gauges: they allow you to check the quantity of fuel remaining in your tank using your smartphone, notify you when your reserve is low and allow you to order instantly from the supplier offering the best price.

Many households order a random quantity of fuel oil from their supplier. When the fuel is delivered, the driver will pour the ordered fuel directly into your tank without really knowing whether it can accommodate such a quantity. The risk of overfilling is therefore high!

The whistle allows the supplier to be alerted in real time when he has to stop discharging his fuel. There are two types of whistles for oil tanks.

The overflow whistle: as the name suggests, it whistles when the oil level becomes too high. This type of whistle has a major disadvantage: it is not always obvious (if not impossible if the pipe is clogged!) to hear it whistle even if the deliveryman sticks his ear against the wall.

The electronic whistle: it is installed in the tank and the delivery person can connect to it using the external pipe. It automatically stops the flow when the tank is filled.

If you do not yet have a system on your tank, you should know that the decree of 01 July 2004 "technical and safety rules applicable to the storage of petroleum products" stipulates that any tank equipped with an automatic filling connection must be fitted with a device to prevent the risk of overflow during filling operations.
