Review on Ultrasonic Water Tank Liquid Depth Level Meter Sensor: High/Low Alarm, Temperature Display, 3.3 Inch LED by Smiley Edwards

Purchasing device domestic water tank; It worked well and had a long range. I placed it 154 feet from the reservoir and behind three walls; The signal overcame walls and distances well. Worked like clockwork for five days. Then on day 5 the display appeared to be partially out, the temperature gauge was working but the level gauge in the tank showed the tank was empty regardless of the actual depth. After relocating the display to the tank to make sure it wasn't a signal issue, I tried contacting the manufacturer but they don't have any contact information in the product documentation. Revain was also unable to obtain the manufacturer's contact information. Returning the device for a replacement by jumping was just a bad device as I had to drill a big hole in the gas cap to install it.
