Ultrasonic Water Monitor
How can I view my tank level in “percentage full”?
The default display for the ultrasonic tank sensor, is to show distance from sensor head to the water surface. If you would like to display the tank level as a percentage full, then you will need to calibrate the sensor via the web dashboard.
You will need to know a few things before you start.
- The distance from sensor head to water surface when the tank is full
- The distance from sensor head to water surface when the tank is empty
- The diameter of the tank
Once, you have collected that info, check out this short video on how to calibrate your tank sensor.
Why are my tank readings erratic?
The most common reason for erratic tank readings, is something blocking the sensor. Make sure there is nothing floating on the water surface, or a ball valve getting in the way. Also ensure there is a minimum of 500mm between the sensor head and the water surface when the tank is full.
My tank is full, but my dashboard is showing 0.5m?
When installing your ultrasonic tank sensor, keep in mind that the minimum distance from the sensor to the water surface is 500mm. That is the minimum resolution of the ultrasonic sensor.
