    I have been using Gallagher wireless water level system on 2 tanks for over 6 years, initially I had many issue with the sensor, making sure it sits at least 150mm above the bottom of the tank and also improvement on the quality of the sensor has resolved this issue. The worst part is the battery that dies after 4-5 years and cannot be replaced, so Expensive to have to replace a tank unit & Sensor Next is the solar panel that becomes opaque and loose efficiency. This needs improvement: Replaceable battery and optional input for external solar panel or power source.
