OPERATION
Each QS100-10 meter is shipped with the K-factor and other information permanently
marked in a rectangular recess on the coverplate.
LEDs Functionality
There are two LEDs on the QS100-10 meter. The GREEN LED is used to indicate basic
power and functionality of the meter. The AMBER LED is used to indicate that there is
a flow of water through the QS100-10 meter. The LEDs will behave in the following
manner to indicate di
ff
erent modes of operation:
MODE
LED BEHAVIOR
Power Disconnected
or Meter Failure:
Both GREEN and AMBER LEDs are OFF.
No Flow Low Power
Mode:
GREEN LED flashes ON/OFF at a rate of
approximately 2 blinks per second.
No Flow or Reverse
Flow Active Mode:
GREEN LED flashes ON/OFF at a rate of
approximately 8 blinks per second.
Low Flow Active
Mode:
GREEN LED flashes ON/OFF at a rate of
approximately 8 blinks per second and the
AMBER LED flashes ON/OFF at a rate that is
proportional to the rate of water flow thru the
meter.
**High Flow Active
Mode:
GREEN LED flashes ON/OFF at a rate of
approximately 8 blinks per second and the
AMBER LED will appear to be constantly ON, but
will be dim.
**NOTE:
To save power it is normal for the LEDs to be dim when flashing at
higher flow rates. At very high flow rates, the AMBER LED will appear to be
constantly ON but dim.
