The Smart Monitoring Watchman Sonic Advanced is a electronic measuring oil tank gauge which monitors how much oil there is left in your oil tank and sets off an alarm in your home in the event of a sudden drop of oil levels. This helps you to ensure that you never run out of oil and are alerted if there is an attempt at theft of your oil. Uses a transmitter on the top of the tank and ultrasonic level measurement techniques to measure the level of oil in a tank continually. Quick and easy to install. Suitable for steel or plastic tanks. 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.
