K-Factor Information

FLOMEC ultrasonic meters use K-factor values for greater accuracy during calibration. These values are derived by calibrating the meters using NIST traceable instrumentation. The K-factor value for this meter is listed below.

IMPORTANT: The K-factor provided is for reference. Accuracy can be affected by plumbing configuration, fluid condition, adjoining pipe schedule, and entrapped air. Customers should always validate accuracy and adjust K-factor as needed using the K-factor adjustment menu of your controller.

INSTALLATION

Meter Components and Features

Below is a QS100-10 meter with labeled components. Familiarize yourself with the meter before installation.

Figure 2

Preferred Installation Layout

Provide a straight pipe run of at least 10 times the pipe’s diameter (Ø) upstream (inlet end) of the meter, and at least 5 times the pipe’s diameter (Ø) downstream (outlet end) of the meter. The word “FLOW” and the arrow embossed on the coverplate denotes the flow direction.

Couplers or unions can be used to install the meter in the piping system; however, for ease of future maintenance or repair of the piping system, it is recommended that unions be used. Unions are shown in all graphics.
For best results, coverplate and wires should be facing up.

Figure 3

Connecting Components

NOTE: Keep the meter bore clean and free of dirt and debris during installation.

1. Remove all D and O.D edge burrs on the pipe ends. (see Figure 4)

2. Clean and apply primer to the pipe ends, fittings and (see Figure 5)
   Note: The joint cementing sequence in 5 and 6 below is for general reference. Use the sequence best suited for your piping and overall layout.

3. Following the PVC cement manufacturer’s instructions, apply PVC cement to a meter end and fitting and quickly assemble while the cement is fluid. Hold the cemented parts together for at least 30
   Repeat for other end of meter. (See Figure 6)

4. Attach meter with attached fittings to pipe ends using the same “cement and hold” process used above. (see Figure 6)
   Figure 4

Figure 5

Figure 6

For Below Ground Installation

Install a valve box around the meter. 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.

Wiring Connections
Below ground wiring connections require a waterproof splicing method to wire the meter wires to the wire cable from the controller. The following splice sequence (Figure 8)
Figure 8a

Figure 8b

Figure 8c

Figure 8d & 8e

shows a 3M DBR/Y-6 splice kit used with 18 AWG wire cable from the controller. See next page for splice instructions and wiring diagram.

Reference Figures 8a thru 8e on previous page

8a. Strip insulation 3/4 in. (19 mm).
8b. With wire ends even, insert wires into the connector and tighten until secure.
8c. Insert the connector all the way into the grease filled 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.
8d. Fold the wires into the channels. 8e. Close the cap.

Optional Above Ground Installation
The meter can be installed above ground as long as proper plumbing and wiring outlined in previous pages are followed, and the meter is positioned with upward flow into the meter to keep it filled for proper operation. (See Figure 10)

Avoid downward flow that can lead to partially filled pipes and inaccurate operation.

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 different modes of operation:

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.

TROUBLESHOOTING

1. The LEDs are the primary indicators of meter performance. Refer to the Operations Section for LED indicating

2. Entrained air is air bubbles suspended in the water Entrained air creates errors in accuracy of ultrasonic technology meters. Recommend a maximum of 10% entrained air in the water flow.

3. The faces of the transducers need to be clean and free of oily substances for accurate 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 11).
   

4. Ensure the flow direction arrow is pointing in the direction of flow for correct LED

NOTES

REPAIR

The QS100-10 meter electronics casing is permanently sealed. All internal cavities and their electronic components are potted with cured electronic resin. There are no serviceable parts in the QS100-10 meter.
