Your Watchman measures the level of liquid in your tank in tenths. When the level is low its red light pulses to attract your attention.

Once your Watchman is plugged into an electrical socket you can read the level of liquid in your tank from its clear display. No need to go out into the cold to check your oil level. A probe is fitted inside your storage tank.

Using new technology it senses the level of liquid and its small transmitter sends this information out by regular radio signals up to 1,000 metres, right into your premises.
