HCS048B Wireless Water Flow Meter FAQ

Why does the screen not light up or show no display?

Possible Causes:

  • Batteries are installed incorrectly, have poor contact, or are depleted

Solution:

  • Reinstall 3 × AAA batteries, check polarity (+/-) and contacts

  • Replace with new alkaline batteries if needed

  • Do not mix old and new batteries

 

Why is “TODAY” not displayed, or only appears after switching pages?

Possible Cause:

  • Time has not been synchronized from the app

Solution:

  • Turn on wireless connection and connect the device to the app

  • After time synchronization, switch pages again to view TODAY

Why does the “TODAY” value not update continuously, or change after connection?

Possible Cause:

  • This is normal behavior — the device updates daily data after time synchronization

Solution:

  • Connect the device to the app regularly to keep time synchronized

 

Why can‘t I switch the unit?

Possible Cause:

  • Unit switching is only available on the FLOW RATE page

Solution:

  • Go to the FLOW RATE page

  • Press and hold the MENU button for 2 seconds to switch units (gal/min or L/min)

Why doesn’t TOTAL1 or TOTAL2 update immediately after clearing?

Possible Cause:

  • Data has not been synchronized with the app yet

Solution:

  • On the TOTAL1 or TOTAL2 page, press and hold the MENU button for 2 seconds

  • Then connect to the app and refresh the data

 

Why is data cleared after re-pairing?

Possible Cause:

  • Re-pairing resets and synchronizes device data

Solution:

  • Avoid re-pairing unless necessary

  • Save important data in the app before re-pairing (if supported by your model)

 

Why does the LAST value not match expected usage?

Possible Cause:

  • If water stops for less than 30 seconds, it is treated as the same record

Solution:

  • Keep the water off for more than 30 seconds before starting the next use
