Q: What does the LED on the 100series indicate?

A: The latest version of the 100series, the 100v3 family, incorporates an LED which indicates how the product is working:

  • LED OFF continuously (blinking ON every 4 seconds) indicates the unit is powered and empty of liquid
  • LED ON continuously (blinking OFF every 4 seconds) indicates the unit is powered, full of liquid which is not flowing
  • LED flashing indicates a flow; the flash rate increases with increasing flow rate
The LED is not fitted on older 125 and 125v2 products.
