Watchman Sonic Oil Level Monitor

Fitting this product was simplicity itself. In fact the job was so easy it actually offered no sense of fulfillment! The sensor worked first time without adjustment. Great value for money and good build quality.

Item would have been very easy to install if the tank I was installing it on (to replace an old monitor) had been correctly drilled. I hadn't realised this initially so contacted the watchman techinal people who were very helpful and friendly,giving me several options to try. It was only when I found that the hole on the inner tank was not directly below the outer hole that the problem became clear, after using hacksaw blade to correct this the monitor worked straight away and reading correctly.

Does a good job and was easy to fit and connect. Good instructions

Easy to fit, working well. Very pleased!

Best price I could find on Amazon and quick delivery. The information was clear and easy to understand and took less than 5 minutes to install. Works a treat. Would definitely recommend 👍🏻

Arrived on time, easy to fit.clear instructions, connected and indicated the level quickly, very happy with this purchase

I’m an old lady but I found the Sonic Oil Level Monitor was extremely easy to set up and start working.

This was a replacement for my 12 year old watchman sonic monitor which had gone faulty. Fairly easy to set up as not much different to the old one. So far working ok with no problems. I have put the plug in monitor on an anti surge lead because these units work on milliamperes and found this prolonged the life of my old one. Prompt delivery by the seller.
