How To Measure and Monitor Your Oil Tank Level

Over the past few months there has been a rise in oil theft from domestic homes that use oil as primary fuel due to living in an off mains area. Its estimated that many thousands of pounds are being stolen each month. with prices for heating oil going through the roof, a recently filled oil tank could be holding well over £1000worth of oil which is great news for thieves. Due to the rise in these theft cases it has prompted a security warning to home owners to lock up their oil tanks and regularly measure the level.

Take a look at this review  of the Watchman Oil Tank Monitor and see why many home owners are not only improving the security of their oil,  but also saving money by being able to see how much they are spending each day. This product is a fantastic way to monitor oil.

The Watchman Sonic is a tank level indicator and uses a transmitter on top of the tank and ultrasonic level measurement techniques to measure, continually, the level of oil in a tank.

This information is accessed via the receiver which is plugged into an electric wall socket within the home. When the level of oil in the tank is below 10 per cent, the fuel dispensing pump symbol appears, indicating to the householder that it is time to order more oil.

How Does It Work?

• The transmitter sits on top of the tank and using ultrasonic level measurement techniques, constantly measures the level of oil in the tank.


• It then transmits that information to the receiver which is plugged into an electric wall socket, located in a convenient place within the house.


• The height of the liquid is displayed on a LCD screen on the receiver. The householder can monitor the level of oil in their tank from inside their home.


• When the level of oil in the tank gets below 10%, the fuel dispensing pump symbol appears, and an option of a buzzing tone, indicating to the householder that it is time to order some more oil.


• In the event of the oil level in the tank dropping at a rate that is not common for a domestic oil tank (more than 1.5cm a minute) the receiver will emit a siren type sound that indicates a theft / leak is occurring
