Water Parameters

Water parameters define how your wasserleser measures and displays water consumption. These settings ensure accurate readings based on your specific water meter type.

Accessing Water Parameters​

  1. Open the stromleser app
  2. Select your wasserleser device
  3. Tap the gear icon (⚙️) in the top right
  4. Navigate to Water Parameters or Device Settings

Key Parameters​

Meter Reading Unit​

Defines the unit of measurement for your water meter:

  • Cubic meters (m³): Standard unit for most water meters
  • Liters (L): Alternative display unit
  • Gallons: For regions using imperial units

The app automatically converts between units for display purposes.

Pulse Rate​

The pulse rate defines how many rotations of the metal disc equal a specific volume:

  • Typically pre-configured based on meter type
  • Common values: 1 rotation = 1 liter, or 1 rotation = 10 liters
  • Usually set automatically during initial calibration

Only adjust if:

  • You know your meter's specific pulse rate
  • Readings are consistently inaccurate
  • Instructed by support

Meter Type/Size​

Some water meters have different specifications based on:

  • Diameter: DN15, DN20, DN25, etc.
  • Flow capacity: Maximum flow rate
  • Manufacturer: Different brands may have different pulse rates

This information helps the app optimize detection algorithms.

Adjusting Parameters​

When to Adjust​

Adjust water parameters if:

  • Initial setup values were incorrect
  • Readings don't match your physical meter
  • You've replaced your water meter
  • You want to change display units

How to Adjust​

  1. Access water parameters in device settings
  2. Tap the parameter you want to change
  3. Enter the new value
  4. Save changes
  5. Verify accuracy by comparing to physical meter
Accuracy Impact

Changing pulse rate or meter type can significantly affect reading accuracy. Only change these if you're certain of the correct values.

Device Name​

You can customize your wasserleser's display name:

  1. Go to device settings
  2. Tap Device Name
  3. Enter a descriptive name (e.g., "Main Water Meter", "Kitchen Supply")
  4. Save changes

This is especially useful if you have multiple wasserleser devices.

Advanced Parameters​

Detection Sensitivity​

Some app versions allow adjusting sensor sensitivity:

  • High sensitivity: Detects even slight disc movements (may cause false readings)
  • Normal sensitivity: Balanced detection (recommended)
  • Low sensitivity: Only detects clear rotations (may miss some readings)

Only adjust if experiencing detection issues.

Measurement Interval​

Defines how frequently readings are recorded:

  • Real-time: Continuous monitoring (higher battery usage for battery models)
  • 1 minute: Standard interval
  • 5 minutes: Reduced monitoring (lower power consumption)

The wasserleser uses USB power, so real-time monitoring is typically enabled.

Parameter Validation​

After adjusting parameters:

  1. Note your physical meter reading
  2. Use a known amount of water (10-20 liters)
  3. Compare app reading to actual usage
  4. Adjust if needed

Resetting Parameters​

If you need to reset all parameters to defaults:

  1. Access device settings
  2. Select Reset Parameters or Factory Reset
  3. Re-enter your water meter information
  4. Recalibrate the device

See LED Indicators for full reset instructions.

Troubleshooting​

Readings are too high/low:

  • Check pulse rate setting
  • Verify meter type is correct
  • Ensure initial reading was set accurately

Units display incorrectly:

  • Change the meter reading unit in settings
  • Restart the app

Can't save parameter changes:

  • Ensure device is online
  • Check WiFi connection
  • Restart app and try again
