The storm water management system in our community includes a pump station that draws water from a pond for irrigation of parts of the community. We wanted a way to measure and track the depth of the pond. We installed the Ultrasonic Level Sensor in the floor of the pump station above the well from which water is drawn (located in a shed). The device measures the distance from the sensor to the top of the water column. The user measures and manually enters the distances between the sensor and the bottom of the vessel and between the sensor and the top of the vessel (or the maximum water level). The device then calculates the depth of water above the bottom of the vessel and displays the depth numerically. The device also calculates the relative fullness of the vessel and displays that graphically. Referring to engineering drawings we entered the difference in elevations between the sensor and the bottom of the pond and between the sensor and the "100 year storm" spillway of the pond. This arrangement enables us to monitor the level of the pond and correlate actual performance with the engineered design of the storm water management system. Installation was easy. The sensor and the display are powered by batteries. Not sure yet how often they will need to be replaced. Wi-Fi connection between sensor and display seems good so far. Instructions are adequate but could be better. Overall, this device is an inexpensive and good solution for the goals we wanted to achieve. Note that the display is not suitable for outdoor use and remote monitoring is not possible beyond the limit of the Wi-Fi connection between the sensor and the display (not sure what that distance is, but it can't be very far). And the device does not store data other than the lowest and highest water levels detected since the last re-set. However, it does what it says it does and is working very well for us so far.

Once I programmed the depth and air gap from sending unit to top of water it works perfect even with the 120 deg.desert sun shining on it. No more trips to the tank to check the level. Wish I bought it sooner!

Not very strongly made but Working well so far,

The first unit I installed failed after 3 days. I complained to the seller and they sent me another one at no charge. The second one works great and I am happy with the performance. It accurately displays the water level in my storage tank. The initial programming is a little complicated but even an old dumb guy like me can do it. I recommend this product.

We have been experiencing water shortages from the town's water supply. We have a raised water reservoir that did not have any gauge on it so I only knew how much water was in it when it overflowed. This unit now hangs within 15' of the reservoir and on our bathroom wall. It has been working fine for 1 week now.
