Review: It saves me a hike to check water level - I use this water level sensor for my 3000 gallon water tank to indicate 500 gallon drop in level. So far it is working great.
Review: Works perfect - This thing works great for my well tank that supplies our house. I put the low sensor about 2 feet from the bottom and put the high sensor right at the top where the tank necks down. When i'm filling it and i hear the alarm go off we cut the well off, then drain a few gallons of water and the alarm shuts off. I'm glad because this allows us to save water and not overflow the tank. The alarm is extremely loud. It is high pitched so the sound doesn't travel super far, but we are about 50 yards from the alarm and can hear it go off, we leave the window cracked to make it easier to hear. At point blank this thing will make your ears ring. I do wish there was an indicator that whenever you first turn the alarm on it beeps one time to let you know the batteries are charged. I wonder about that battery dying one day and we don't realize it, we rely on this to tell us if our tank ever gets too empty. I'll probably end up replacing the battery once every 6 months just to be on the safe side. Well worth the $35.

## Features

- 【Dual 5 Meter Floating Probe Design】- It can detect water shortage or overflow. You can choose to use one or both functions according to your needs. The overflow probe is placed above the water level. When the water level rises to the detection position, the float will rise and trigger the magnetic induction, thus triggering the alarm. Instead, the water shortage probe is always placed in the underwater position, which triggers an alarm when the water level drops below the float.
- 【120 dB with Red Light Strobe Alarm - Volume Adjustable】- The volume of the water alarm can be adjusted according to the installation distance, and the alarm can also be used as a home safety alarm. You can DIY yourself, the alarm will be triggered when the two wires on the probe are shorted.
- 【Extendable Detection Line】- The detection line of this water detector can be extended to 164ft to meet the needs of your family. Please use good quality copper core extension wire.
- 【Low Power Design】- 9V replaceable battery power supply, standby for more than 1 year. When the battery power is low, the water sensor sound will become small or there is no alarm sound. Please replace the battery at this time.
- 【Wide Range of Uses】- This dual probe water level detection alarm can be used in many scenes, such as solar water tank, fish tank, swimming pool, basement, warehouse, bathroom, kitchen, laundry, etc. In addition, this high decibel alarm can also be connected with other sensors to become a home safety alarm system
