Watchman Alarm Oil Tank Gauge Information
The sender attaches to your oil tanks and is powered by batteries. The receiver shows the fuel level in your oil tank in tenths and may be plugged into any electrical socket up to 250 metres from your tank. When the fuel is low, a red light draws your attention.
Additionally, it detects any unexpected reductions in the fuel level in your tank, at which point the plug-in starts to sound an alarm to let you know there might be an issue.
Most single-skin and bundled plastic oil tanks on the market can easily be fitted with them. It can also be mounted on a steel oil tank, but it must be spaced out from any stays inside the tank for it to function.
