Calculating the Water Change Volume
The volume can be calculated by multiplying the width and length
of your tank and the distance between the pyramids of the two
sensors.*
For example, a tank is 18 inches in length and 17 inches in width. If
the distance between the two sensors is 3 inches, the water change
volume is approximately 4 gallons.
18" (L) X 17" (W) X 3" (H) = 918 cubic inches (around 4 gallons)**
* The water volume might be in uenced by factors such as the
speed of return pump.
**231 cubic inches = 1 US gallon
