Best Oil Level Monitor Reviews 

Thanks for taking your time to read our reviews on the best oil level monitors that are currently available on the United Kingdom marketplace. These are useful as a general gauge to your oil level.

The accuracy of these can vary depending mainly on how old your oil tank is and on its shape. If you take the time and calibrate it accurately during the installation they are about 90% accurate. They work by ultrasonic and will send a radio signal up to 200m to your house where a display will tell you the level of the oil.

I used to have one of the old float type gauges on my tank. They worked perfectly well but in reality i never looked at it and i ran out of oil on more than one occasion. Now I have a Watchman monitor. The display is in my utility room and I see it 10 times a day and haven't run out of oil since. They should make these standard equipment on all tanks!

Just below you will see our top oil level monitors. However, and this is a first for me on this site, I have put the Watchman Sonic Oil Level Monitor as first, second and third on my list! Its really the only one to go for, though I have included the next best seller ( which is more expensive and not as good ). I have also added a mechanical gauge that might suit if there is no power.
