Droplet is designed to automatically calibrate over time by learning your home’s unique water usage patterns. However, if you’re noticing inaccurate readings or flow detection issues, using the Manual Calibration feature can help improve volumen accuracy.
Please be aware that the zeroing process can take up to 48 hours. It is recommended to wait at least 48 hours before manually calibrating your Droplet.
🧪 What Is Manual Calibration?
Manual Calibration is a quick in-app process that allows you to:
Confirm the volume accuracy of your Droplet’s flow readings
Help Droplet learn the precise characteristics of your home’s water system
This is especially useful if:
You’ve recently reinstalled Droplet in a new location
You're seeing inconsistent or inflated gallon totals
The device seems too sensitive or not sensitive enough
You're running on well water or a pressure tank setup
📲 How to Access Manual Calibration
You can launch Manual Calibration directly from the Droplet mobile app:
Open the Droplet app
Tap Menu (☰ icon in the top-right corner)
Go to Droplet Settings
Tab Accuracy Tools
Select Check Accuracy
Follow the on-screen steps to perform a 0.5 / 1-gallon (or 2 liters) container test
(Make sure no other water is running during this test)
📝 Tip: You can use any household container (e.g., a gallon jug or large measuring cup). The key is to run exactly one gallon of water while Droplet listens and adjusts its baseline.
💡 When Should I Use Manual Calibration?
We recommend using it:
48 hours after first setup (especially if your readings seem off)
After relocating Droplet to a new section of pipe
If your water system includes variable flow, multiple pumps, or irregular pressure
If the app prompts you during onboarding or troubleshooting
You can run the test as often as you like — it won’t harm anything, and it can help refine the accuracy over time.
