PROTECT YOUR OIL! With the Watchman Sonic Advanced, you can monitor your oil tank contents 'at a glance' from your home, no need to walk outside to the tank. In the event of the oil level in the tank dropping at an unusual rate the receiver will emit an audible alarm.

How it works

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 an 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, indicating to the householder that it is time to order some more oil.

Upgrade to a smart monitoring system with the USB Receiver. This lets you transform your Watchman Sonic Advanced, into a smart Wi-Fi tank level monitor. Enables you to control your oil levels through a smartphone app without being tied to a single location. The SENSiT USB receiver and app alerts you of low levels, sudden drops, predicted run out and consumption monitoring notifications directly to your phone. The SENSiT even works with Alexa, so when asked 'How much oil is in my Tank?', she will be able to let you know!
