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

Low price and made in China. Couldn't resist the cheap price of an in-tank ultrasonic level sensor, but I suspected a waste of money. Instructions were complete but very difficult to understand without troubleshooting help. After installing it by trial and error, everything worked for me as instructed. Monitored the level in the tank for 50 days, after which it stopped showing any level. He stated the batteries were fine, but replaced them with new ones and then reinstalled them, but still not charging. There was nothing I could do to fix the problem, so the device is unusable.
