K-Factor Information
NOTE: The meter size is molded on the vertical arm of the Tee
FLOMEC ultrasonic meters use K-factor plus offset numbers for greater
accuracy during calibration. These values are derived by calibrating the
meters using NIST traceable instrumentation. Using both sets of values to
calibrate the meters provides greater accuracy than using only a K-factor
value. The K-factor and offset values for each meter are listed below.
IMPORTANT:
The K-factors provided are for reference. Accuracy can
be affected by plumbing configuration, fluid condition, adjoining pipe
schedule, type of meter tee (if using QS200 insert in non-FLOMEC tee),
and entrapped air. Customers should always validate accuracy and adjust
K-factor as needed.

NSF CERTIFICATION INFORMATION
NOTE: QS200 meter are available as a standard meter, or as an
NSF certified meter. Only QS200 meters ordered as a complete unit
(ultrasonic insert installed in FLOMEC tee) qualify to be NSF certified.
Standard meter:
The identification plate on the top of the ultrasonic
insert is marked “QS200”.
NSF certified meter:
The identification plate on the top of the
ultrasonic insert is marked “QS200PW”, and the tee body is marked
with an NSF certification decal for additional identification.
NOTE: NSF certified meters use the same part number structure as
non-NSF models, except for the addition of the “PW” suffix on the end.
The “PW” suffix indicates an NSF certified meter. e.g., QS200-15PW.
NSF certification is valid only
when product is marked per
above information.
