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

Just installed a depth gauge. It works perfectly. There are no problems synchronizing the display with the sensor. We have a display mounted about 60 feet from the sensor. You need 6 AAA batteries for the sensor and 2 AA batteries for the display. The display was easy to program with the included instruction manual. My aquarium is about 8 feet deep. With a quick glance you can see how much water is left in your aquarium.

This unit works fine but there is a problem with the controller and the minimum allowable air gap between the top of the maximum water level and the sensor. Not many tanks I know have a big gap. This device requires quite a bit of clearance and is therefore not accurate when the tank is full as you cannot set it to the actual level. There's also no calibration, so you can tweak the settings a bit to be more accurate.

It didn't work. I believe we installed it correctly and within 100 feet of the transmitter with no interference. Small chance my Verizon antenna was interfering, but the frequency was different so I ended up marking it as pure junk. My aquarium is 10 feet tall and about 5 feet in diameter. The space requirement between the sensor and the high tide line (greater than 2 feet) is also an issue. We managed to get 2.25 feet on a tank, but most tanks don't have that.

This item is junk, it doesn't work, it wasn't difficult for me to figure out how to set it up and only to find out that it only tells me the temperature of the water in the tank, not the water level, i guess after all the bad reviews i read about this item i shouldn't have received it but hey you live and find out don't buy this item and if you just asked for your money the back .

After two weeks, the water level display and the water level value no longer work, the tank is reported as empty with a value of 0.0. I informed Revain who kindly gave me a partial refund as the return date had already passed. I tried resetting it, but when I took the batteries out and then put them back in, the receiver just died. the display is completely blank. It's a shame as it worked fine for 2 weeks but the quality seems very poor. :(

I understand why a lot of people have problems with this product. The instructions are poorly written. For it to work, insert batteries into both units and then press and hold the 'Set' and 'Alarm' buttons on the display unit without setting the tank depth. Phew, it's working properly now. I set the tank depth according to the instructions when installing the batteries, but the value was completely wrong. My display has no problem in the trailer about 100 feet from the tank.

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…

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…

This device stopped working two weeks after installation. At first he had problems with the morning condensate, which indicated that the tank was only half full. After two weeks the water level indicator disappeared. I stuck with the tank temp which indicated the batteries and transmitter and panel were working but the ultrasonic sensor was not working. I worked with the seller for a month via slow email. Changed batteries twice. Eventually he wanted me to video the battery change, but I…
