Hydrawise®HCC models only.
K
-Factor Information
NOTE:
The meter size is molded on the vertical stem 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 greateraccuracy than using only a K-
factor
value.
The K-factor and offset values for each meter are listed above.
IMPO TANT:
The K-factors provided are for reference. Accuracy can be affected by plumbing configuration, fluid condition, adjoining pipe
schedule,
type
of meter tee (non-FLOMEC brand), and entrapped air. Customers should always validate accuracy and adjust K-factor as needed.
If using non
-FLOMEC tees, K-Factor will be different from those
shown. Inconsistencies with these tees affect any stated value. Customers must
verify accuracy if concerned.

INSTALLATION
Below is a typical QS200 meter with labeled components.
Familiarize yourself with the meter before installation.
Figure 2

10
INSTALLATION (Continued)
QS200 ultrasonic sensors should be installed in a ground box with straight runs of pipe equal
to 10 pipe diameters upstream, and 5 times the pipe diameter downstream to prevent
turbulence that can decrease the sensor’s accuracy. Without these straight runs, QS200
sensors will still detect higher and lower than expected flows and unscheduled flows. The
arrow embossed on the insert body denotes the flow direction.
Figure 3
Install Meter onto Pipe
NOTE: There is no need to remove the insert to install the meter. The meter must be installed
with the arrow on the insert pointing in the flow direction.
If the meter is accidentally installed backwards, simply remove the insert, rotate 180 degrees
so the arrow points in the flow direction, and reinstall the insert.
The Tee is bi-directional; the insert is not. The insert operates correctly as long as the insert
arrow is pointed in the direction of flow. The insert can be rotated 180 degrees, so its arrow
can always be pointed in the direction of flow regardless of Tee installation.
If space allows, install Tee/insert at a 60° to 90° angle from vertical (see Figure 3).
NOTE: For 1-inch pipe installations, this 60° to 90° angle is especially important for the most
accurate meter operation.
Note: Flow must go uphill through the meter, never downhill through the meter to avoid air
bubbles or air pockets captured in the Tee.

11
INSTALLATION (Continued)
1. Remove all burrs from the pipe ends I.D. and O.D. edges and the Tee sockets I.D.
edges (see Figure 4).
2. Clean and apply primer to the pipe ends and Tee sockets (see Figure 5)
3. Apply PVC cement to pipe ends and Tee sockets and quickly assemble the parts while
the cement is fluid. Follow the cement manufacturer’s instructions (see Figure 6).
4. Hold the cemented parts together for at least 30 seconds.
Figure 4 Figure 5
Figure 6
For Below Ground Installation
Install a valve box around the insert. Valve box extensions may be needed, depending on
depth (see Figure 7).
NOTE: A minimum of 10 in. thick layer of gravel should be installed immediately below the
meter and valve box.
Figure 7

12
INSTALLATION (Continued)
Wiring Connections
NOTE: Wiring diagram is shown in next section.
1. When using 18 AWG cable, cut off the unused wires so that they are even with the
sheath of the cable.
NOTE: For 18 AWG connections, remember the color of the wires you use so that you can
make an identical connection with the same wires later.
2. 3M DBR/Y-6 Splice Kit Instructions:

13
INSTALLATION (Continued)
a. Strip insulation 3/4 in. (19 mm).
b. With wire ends even, insert wires into the connector and tighten untilsecure.
c. Insert the connector all the way into the tube until the connector rests on the bottom
of the tube.
NOTE: If having difficulty getting the twist-on connector down into the tube when using
small gauge wires, use a thin, non-conductive object to push the connector to the bottom
of the tube. Upon removal of the object, ensure that no voids or water paths remain in
the grease.
d. Fold the wires into the channels.
e. Close the cap
Wiring Connections
This diagram shows connection to a RAIN BIRD® Flow Smart Module. Connections to other
flow controllers may vary.
Figure 9

14
OPE ATION
Each QS200 meter is shipped with two K-factor decals (placed loose inside the owner’s
manual packet). One is to affix on or near the installed meter for on-site use if desired. The
other decal is to affix to a convenient spot on or near the controller for immediate reference
if desired.
LEDs Functionality
There are two LEDs on the QS200 product. 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 QS200 meter insert. The LEDs will behave in the following manner to
indicate different 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.

15
T OUBLE SHOOTING
1. The LEDs are the primary indicators of meter performance. Refer to the Operations
Section for LED indicating functionality.
2. Entrained air is air bubbles suspended in the water flow. Entrained air creates errors in
accuracy of ultrasonic technology meters. Recommend a maximum of 10% entrained
air in the water flow.
3. Flow must go uphill through the meter, never downhill through the meter to avoid air
bubbles or air pockets captured in the Tee.
4. The faces of the transducers need to be clean and free of oily substances for accurate
operation. Do not touch transducers with fingers, oily rags, etc.
DO NOT use wire brushes or abrasives to clean the faces of the transducers (see
Figure 10).
5. Ensure the flow direction arrow is pointing in the direction of flow for correct LED
functionality.
6. Ensure the quick release pin is installed in the tee to maintain pressure and alignment
of the insert in the tee.
Figure 10

EPAI
QS200 Insert eplacement and
QS200 etrofit Insert Installation Instructions
NOTE: These instructions are intended to assist in replacing the insert in an existing
FLOMEC
®
QS200 ultrasonic Meter.
These instructions also apply when a FLOMEC QS200 insert is used as a replacement insert
in other brands of Tee type meters that have an obsolete or unreliable insert.
The FLOMEC QS200 is a direct replacement for a paddle wheel type insert in most meters
that have a Tee type housing.
Keep the new insert free of dirt and debris during installation.
Check Meter Size
If your flow controller requires a meter K-factor, use the K-factor for your size meter (see
SPECIFICATIONS section). If the meter size is unknown, it is easily determined using one
of the following methods (for FLOMEC and other brands):
1. Dipstick Method (For 2 in., 3 in. and 4 in. meters only): The interior depth of the meter
body indicates its size. To check, remove the old insert from the meter body and insert
the end of a stiff tape measure down into the insert bore until it touches the bottom of
the meter body bore. Read the depth shown on the tape measure at the top of the Tee
housing (see Figure 11) and compare with dimension “D” in the specifications section
(see Figure 1).
2. Line Pipe Size Method: Normally, the line pipe size is the same as the meter size. Figure
12 shows line pipe sizes.
NOTE: FLOMEC Tees are marked with hallmark of size, part number, SCH80 and pressure.
Figure 11

EPAI (Continued)
emove Old Insert From Tee
1. Clean all dirt and debris away from the immediate area of the old insert and the top of
the meter then pull out the quick release pin from the meter (see Figure 13).
2. Remove the old insert. Grasp the insert flange with your hand and pull straight up and
out of the Tee, making sure no dirt or other particles fall into the insert bore of the meter
(see Figure 14).
NOTE: The FLOMEC Multi-Tool (P/N 146055-501) can be used to make removal of old insert
easier (see Figure 17).
NOTE: When replacing another manufacturer’s insert with the QS200 Retrofit Insert, the old
insert could have a sediment or mineral buildup and need to be leveraged out of the tee.
Figure 13 Figure 14

19
EPAI (Continued)
Install New or eplacement Insert Into Tee
1. The Tee insert bore must be clean before installing the insert and the (2) black O-rings
on the insert should be fully lubricated.
2. Orient the insert over the insert bore so that the arrow on the insert is pointing in the
direction of flow.
3. Insert the insert straight down into the Tee.
4. Push down on the insert flange and twist slightly to install, and to align the retaining pin
holes in the insert with the holes in the Tee (see Figure 15).
NOTE: The FLOMEC Multi-Tool (P/N 146055-501) can be used to make installing new insert
easier (see Figure 18).
NOTE: The O-rings on the outside of the QS200 Retrofit Insert are square profile O-rings.
When installing in another brand of Tee, if the insert fits too tight into the Tee, replace the
square profile O-rings with the round profile O-rings included with the QS200 Retrofit Insert.
Their installation could make installation easier in tight fitting Tees. The O-rings must be fully
lubricated before insert installation.
5. Next, replace the quick release pin (see Figure 16).
6. Using the splicing and wiring information (see WIRING CONNECTIONS and WIRING
DIAGRAM in the INSTALLATION section), connect the wiring from the new insert to the
wiring cable of the controller.
7. Energize the insert and verify that it is operating properly (see Troubleshooting section
if required).

The multi-tool was designed exclusively for tee type meters that use an insertion type insert.
It facilitates easier removal of the insert, whether from a QS200 meter or other brands of tee
type insertion meters.
It is especially useful when attempting to remove an old, inoperative, or inaccurate insert
from another brand of tee type insertion meter for replacement with a QS200 insert.
The multi-tool is versatile, compact and fits easily into the valve box for close quarters use.
The pointed end is designed for use as:
1. A versatile pry bar and driving wedge. On other brands of tee type insertion meters,
when the insert lip may be too close to the top of the tee to use the U-formed end of the
multi-tool, use the pointed end (as pry bar or driving wedge) between the insert lip and
top of the tee to break the insert loose and gain room between the insert lip and tee to
use the U-formed end to lever the insert up and out.
2. An alignment tool to align the pin holes of the new insert with the pin holes in the tee.
3. A cleaning tool for clearing debris from the valve box lid groove or other crevices.
The U-formed end is designed for use as:
4. A handle for leverage when using the pointed end.
5. A levering tool by slipping the U-formed end around the insert between the insert lip and
the top of the tee. This positions the tool for use as a lever for levering inserts up and
out of the tee for replacement. It can be levered up or down, and can be rotated to any
quadrant around the insert in order to give the best position for leverage.
The multi-tool (P/N 146055-501) is a separate item available to the customer, and is listed in
the repair parts list near the back of the manual.
