2. METER INSTALLATION
2.1
Installing the Enclosure
The first step to installing and running the flowmeter is to install the enclosure. There are two methods of
mounting the enclosure: directly or by using the mounting ears.
2.1.1 Direct Mount Method
The enclosure can be directly mounted to a wall by inserting four 1/4-inch screws into the mounting wells
from the front of the enclosure.
2.1.2 Mounting Ears Method
The enclosure can also be mounted to a flat vertical surface using the mounting ears as follows (Figure
2.1-A):
1. Screw the four mounting ears to the metal threaded inserts on the back of the enclosure using the
5/16-inch screws provided in the mounting ears kit.
2. Attach the ears to the wall with standard mounting screws.
FIGURE 2.1-A
4
2.2
Wiring the Meter
All wiring should be routed through conduit or cable glands to seal the enclosure. The recommended
cable routing is illustrated in Figures 2.2-A and 2.2-B.
Figures 2.2-A (left) & 2.2-B (right)
2.3
Power Input Terminals
To prevent damage to the instrument, verify that the voltage to be connected
matches the voltage rating of the flowmeter. The voltage rating is indicated beneath
the power input terminals.
The power input terminals seen in Figure 2.2-A can be connected to one of the following input voltages:
•
85 to 265 Vac
•
10 to 32 Vdc
The sheet metal access cover must be removed to gain access to the power input terminals and replaced
after the connections are completed. Power should be connected in accordance with local standards
or codes of practice.
Disconnection from the supply MUST be possible via a customer-supplied switch or circuit
breaker. This disconnection device should be clearly marked, in close proximity to the
recorder, and easily accessible to the operator.
To connect power for 120/240 Vac operation:
1. Connect the hot wire to the L1 terminal.
2. Connect the neutral wire to the N terminal.
3. Connect the ground wire to the GND terminal.
5
..... Power input terminals
To connect power for double phase 240 Vac operation:
1. Connect one hot wire to the L1 terminal.
2. Connect the other hot wire to the (L2) terminal.
3. Connect the ground wire to the GND terminal.
To connect power for 10 to 32 Vdc operation:
1. Connect the positive wire to the terminal labeled + (N).
2. Connect the negative wire to the terminal labeled - (L1).

3. TRANSDUCERS
3.1
Wiring the Transducers
The transducer terminals and cables are arranged in pairs and are labeled DN STREAM and UP
STREAM. The downstream transducer cable has blue-banded ends; the upstream transducer has redbanded ends.
FIGURE 3.1
Locate the symbol seen in Figure 3.1 (left). This symbol is on both
pairs of terminals and indicate which terminals should connect to the
center wire conductors and which should connect to the coaxial
shields.
3.2
Spacing and Mounting the Transducers
Transducers (xducers) can be mounted with the V, W, or Z method.
3.2.1 V Method
The V method is considered the standard method.
Figure 3.2-A: V Mount
3.2.2 W Method
Flowmeter performance on small pipes with outer diameters of 2.5 inches (63.5 mm) or less can be improved
by using the W method. See Figure 3.2-B (page 8).
7
..... W method
Figure 3.2-B: W Mount
3.2.3 Z Method
The Z method is used primarily in applications where the V method cannot work due to signal attenuation
from excessive air or solids in the liquid, thick scale, poorly bonded linings, or very large pipes. Additionally, the Z method generally works better on larger diameter pipes where less pipe length is available for
mounting.
FIGURE 3.2-C: Z MOUNT
8
..... Z method
To mount transducers using the Z method:
1. Establish a reference at both the 3 o’clock and 9 o’clock positions on the pipe (Figure 3.2-D, below).
2. Place a transducer at the 3 o’clock position.
3. Trace the shape of the 3 o’clock transducer along its inside edge (opposite the cable connection).
Draw a horizontal line at its center. Remove the transducer (Figure 3.2-E, below).
4. Obtain a continuous sheet of paper longer than the circumference of the pipe. Calculator paper tape or
thermal printer paper works well for this.
5. Fold one end of the paper across the pipe’s width to produce a clean, straight edge.
6. Line the fold of the paper up with the horizontal centerline of the 3 o’clock transducer (Figure 3.2-F,
below).
7. Wrap the paper firmly around the pipe, and mark the intersection point where the fold comes in
contact with the rest of the paper (Figure 3.2-G, below).
FIGURES 3.2-D THROUGH 3.2-G (LEFT TO RIGHT, TOP TO BOTTOM)
8. Remove the paper from the pipe. Place the fold and intersection mark together again, and fold the
paper exactly in half (Figure 3.2-H, page 10).
9. Mark along the new fold (Figure 3.2-I, page 10).
10. Draw a horizontal line along the pipe from the centerline of the 3 o’clock transducer position. Refer to
Figure 3.2-J (page 10), and use a level to ensure that the line is level with the top of the pipe. The line
should be at least 3 inches (76 millimeters) longer than the transducer spacing calculated by the
software. For example, if the software calculates the spacing as 14 inches (356 millimeters), draw a
line 17 inches (432 millimeters) long.
9
..... Z method
11. Measure the spacing from the inside edge of the 3 o’clock transducer, and mark this on the pipe
Figure 3.2-K, below).
12. Wrap the paper firmly back on the pipe. Have the point where the ends of the paper come together
line up with the horizontal line on the 3 o’clock side of the pipe. Ensure that the inside corner of the
straight edge of the paper is aligned with the mark made for the transducer spacing. Tape the paper
down, or have someone hold the paper in place (reference Figure 3.2-L, below).
FIGURES 3.2-H THROUGH 3.2-L (LEFT TO RIGHT, TOP TO BOTTOM)
13. Go to the other side of the pipe (9 o’clock position), and mark the pipe at the point where the marked
fold and the inside edge of the paper length intersect (Figure 3.2-M, page 11).
14. Remove the paper from the pipe and trace the shape of the 9 o’clock transducer in the same manner
you did for the 3 o’clock transducer. Ensure that the inside edge of the transducer (opposite the cable
connection) is even with the point just marked on the 9 o’clock side of the pipe (Figure 3.2-N, page
11).
10
..... Z method
FIGURES 3.2-M (LEFT) & 3.2-N (RIGHT)
15. Refer to Figure 3.2-O (below), and mount the transducers with pipe straps.
FIGURE 3.2-O
The figure below illustrates the final Z method installation.
FIGURE 3.2-P
11
3.3
Insertion Transducers
3.3.1
General
Insertion transducers should be considered where pipe conditions attenuate the ultrasonic signal of clampon transducers, preventing adequate flow readings. Such examples are:
•
very large pipes with a wall thickness greater than 1”
•
porous pipes such as concrete or clay
•
mortar lined pipes where the lining may be cracked or broken
•
pipes that may have a significant build up on the inner wall

3.3.3
Template Installation*
*May be supplied with original transducer purchase.
1. Cut out a template from a roll of mailing paper, butcher block paper, or a similar type of paper. Ensure
the corners are square (Figure 3.3-B, below)
2. Fold template exactly in half and crease in the middle (Figure 3.3-C, below).
Figures 3.3-B (left) & 3.3-C (right)
3. Wrap the template around the pipe so that the crease is on one side of the pipe and the two ends of
the template meet on the other side of the pipe.
Try to line up the crease and ends with the horizontal center of the pipe. Tape the ends of the
template together with masking tape to hold it in place on the pipe. On a horizontal pipe, rotate the
sleeve until the crease is in the 2 o’clock to 4 o’clock position.
Figures 3.3-D & 3.3-E: Completed Template
13
3.3.4
Transducer Installation
1. Choose one of the following options to install the 1.5” nipple:
•
directly onto the pipe
•
directly into a pipe saddle (reference Section 3.3.5 for tapping procedure)
•
directly into a threadolet (reference Section 3.3.5 for tapping procedure)
The user must decide which of the above is the preferred method of installation.
2. Screw the 1.5” nipple onto the pipe usingone of the options stated in step 1. Use Teflon tape as
needed to create a leakproof seal.
3. Screw the 1.5” ball valve assembly onto the 1.5” nipple.
4. Loosen the collar, and pull the transducer assembly all the way out.
5. Screw the transducer assembly into the ball valve.
6. Take the measurement for distance A (seen in Figure 3.3-G).
7. Calculate X (seen in Figure 3.3-G).
8. Move the collar away from Point B the distance you calculated for X, and lock the collar.
9. Turn the valve handle to the “on” position and insert the transducer until the collar is seated on the seal
housing.
10. Tighten the retainer onto the seal housing.
3.3.5
Tapping Procedure
Follow these steps if you are installing the 1.5” nipple directly into a pipe saddle or directly into a threadolet.
This procedure is to be performed by a qualified installer only.
1. Using Teflon tape, wrap the end of the male nipple and screw into the threadolet.
2. Screw ball valve onto nipple, and adjust valve to the “open” position.
3. Connect tapping machine into end of ball valve.
4. Use 1.12” minimum bit and drill through the pipe wall.
5. Back the bit out past the valve assembly, and move the valve handle to the “off” position.

3.4
Site Recommendations
Based on the setup parameters, WinGateE automatically calculates the required transducer spacing. The
next step is selecting a proper transducer site. Figure 3.4-A and the following questions will assist you in
choosing a proper installation location:
•
Is the section of pipe always full of liquid?
•
Are there at least five pipe diameters upstream and three pipe diameters downstream from any
directional changes, pipe joints, or narrowing/widening of the pipe?
Conditions at these locations in Figure 3.4-A can interfere with the transmission of the ultrasonic wave and
yield inaccurate or unreliable flow readings.
FIGURE 3.4-A
• A - pipes may not be full
• B - down flow
• C - too close to the elbow
• D - air collects at the top of horizontal pipe
• E - sediment collects at the bottom of horizontal
pipe
Once you have selected the appropriate installation site and mounting method, you can now mount the
transducers onto the pipe:
1. Clean the area of the pipe where the transducers are to be installed. Remove any rust, scale, or loose
paint. Well-bonded paint does not need to be removed.
On horizontal pipes, the transducers should be mounted in the 3 o’clock and 9
o’clock positions. This prevents sediment from building up along the bottom of
the pipe and gas bubbles or air pockets from forming along the top of the pipe.
2. Apply a wide bead of sonic coupling compound lengthwise down the center of the face of each
transducer.
The coupling compound should squeeze out from around the edges of the
transducer when it is in place. There should be no air gaps between the transducer
and the pipe.
For pipes 2.5” (63.5 mm) or smaller refer to Appendix A: Measuring Flow on Small
Diameter Pipes.
3. Attach the transducers to the pipe using the stainless steel pipe straps. Tighten both straps securely,
ensuring that the transducers are aligned to the pipe.
16
..... Site recommendations
4. Connect the transducer cables to the instrument.
Reversing the position of the upstream and downstream transducers or the
transducer cable connections to the meter will result in negative flow readings.
5. Tighten the transducers sufficiently to prevent them from slipping and to allow for proper operation of
the flowmeter.

7.1.5 Calibrating the Flowmeter
7.1.5.a Scale Factor
After the instrument’s zero point has been set and verified, a scale factor can be set to adjust the
measured flow. The flow measured by the instrument is multiplied by this scale factor. For example, if the
displayed flow is twice the actual flow, a scale factor of 0.5 divides the displayed flow by two.
The scale factor is preset at the factory and is imprinted on the transducers. If an additional scale factor is
required by the user, the additional factorshould be multiplied by the factory scale factor. Enter the result in
the Scale Factor text box.
Always determine the scale factor at the highest possible flow rate achievable in
order to maximize the accuracy of the scale factor.
1. Enter the number to be used as the scale factor in the Scale Factor text box.
2. Click Send.
Once the flowmeter has received the information, the Flow screen will be displayed.
33
7.1.5.b Zero Set
Once the meter is installed, a small adjustment to the zero point, called zero set calibration, may be
required. Zero set calibration allows the flowmeter to read very close to zero under zero flow conditions.
Prior to performing a zero set calibration, follow these steps:
1. Ensure the transducers are connected to the pipe and the instrument is reading flow.
2. Disable the low flow cutoff to allow the calibration to be verified.
Begin the zero set calibration:
1. Click on the Zero Flow button.
FIGURE 7.1-X
2. Click Yes to perform the zero setcalibration. Then click Send. The Flow screen will be displayed.
Click No if you do not want to perform the zero set calibration.
7.1.5.c Manual Zero Set Method
The zero point can be manually entered with the manual zero set method.This method applies a constant
offset entered by the user.
1. Follow the preliminary steps outlined in Section 7.1.5.b
2. Minimize the flow occurring in the pipe.
3. Set the damping so that the flowmeter reads a steady flow.
4. Enter 0 in the Zero Flow text box.
5. Click Send.
6. Take ten separate flow readings, and determine their average. This average is designated as the
variable P for positive.
7. Disconnect the transducer wiring connections at the flowmeter, and reverse the upstream wires and
downstream wires. The flowmeter will begin to display a negative flow reading.
8. Allow the flowmeter to settle for 10 minutes.
34
..... Manual zero set method
9. Take another ten flow readings, and determine their average. This new value is designated as the
variable N for negative.
10. Determine the manual zero point (Zp) by calculating the following formula:
11. Enter this number in the Zero Flow text box.
12. Click Send.
13. Reconnect the transducer wires according to their original orientation. Once the flowmeter has
received the information, the Flow screen will be displayed.
7.2
Options Tab

•
the unit identification number, using any whole number between one and 32,000
The Display section can be configured to indicate any combination of flow rate, totalizer, or signal strength
values. For multiple selections, enter a cycle time which allows the display to alternate between
selections.
35
..... Comm/Displays & display
If you do not make any selections, the meter will default to factory settings and display flow and date/time
values.
FIGURE 7.2-B
7.2.2 Flow
7.2.2.a Low Flow Cutoff
FIGURE 7.2-C
When a zero flow condition occurs, internal sloshing and other
fluid movement can prevent the flowmeter from reading total zero.
This can result in totalizer errors. These errors can be minimized
by entering a low flow cutoff. Setting a low flow cutoff drives the
flowmeter to zero for flow rates at or below that value.
7.2.2.b Low Signal Cutoff
Empty pipes, solids, bubbles, or voids in the flow stream may cause temporary drops in signal strength.
The effect of these dropouts can be minimized by setting a low signal cutoff.
7.2.2.c Damping
The damping coefficient suppresses short term fluctuations in the indicated flow rate. Increasing the
coefficient increases the response time to changes. Damping should be kept at a minimum unless the flow
rate fluctuates wildly. If so, damping should be increased just enough to reduce the fluctuation to an
acceptable degree.
The value for the low flow cutoff should be set as high as is practical to maximize
the stability of the zero flow setting.
The value for the low signal cutoff should typically be set at approximately onehalf of the value of the signal strength present under low flow conditions.

the transducers and forming a bead along the edges.
The following sonic coupling compounds are recommended:
•
SIL-GLYDE®, which is made from a silicon base and is suited for most transducer installations. It is
rated for pipe skin temperatures from -20ºF to +400ºF (-28.9ºC to 204ºC).
•
Dow Corning® 111 or similar high temperature couplant, which should be used for applications with
pipe skin temperatures up to 470ºF (243ºC).
•
GE® RTV-108 or similar silicon RTV, which should be used for underground or submerged
transducer sites or sites where a more permanent bond is required. The RTV should be completely
cured prior to covering up the transducer site or taking readings.

12. HAZARDOUS AREA INSTALLATION
This chapter covers requirements for installing the INSTRUMENT in hazardous area applications. Hazardous
area certification for North America is provided by the Canadian Standards Association (CSA). Certification
for Europe is provided by Laboratoire Central des Industries Electrique (LCIE).
The area classification determines the type of enclosure to be used and whether barriers are required. If
barriers are required, they are installed by the factory to meet the appropriate agency certification.
The standard enclosure for the instrument is a NEMA 4X (IP65).
If transducers are approved for use in hazardous areas, a logo of the certifying agency is affixed to the
transducers.
12.1 North American Certification
The transducers are certified by CSA as follows:
•
Intrinsically safe (IS) transducer for Classes I and II, Div. I, Groups A, B, C, D, E, F, and G (IS barriers
required);
•

APPENDIX A: MEASURING FLOW ON SMALL DIAMETER PIPES
A.1
General
To enhance stability when measuring flow on 1.5 to 3.5 in. stainless steel or copper pipes OR 1.5 to 2.5 in.
PVC, carbon steel, or other pipes at an operating temperature range of -20ºF to +240°F, follow the steps
outlined in section A.2.
The W mount method is recommended for pipe sizes equal or less than 2.5 in. unless signal strength is
less than 50%. However, the V method is used when the W method cannot work due to signal
attenuation from excessive air or solids in the liquid, thick scale, or poorly bonded linings.
A.2
Instructions
1. Wipe off any grease on the coupling surface of the transducers. Remove any oily residue with
alcohol or detergent from the surfaces, and allow to dry.
2. Using a pencil, draw two lines on each transducer so that the spacing between the two lines is in the
center of the transducer surface.
The space between the two lines should be:
•
•
•
•
0.50 in. for 3.0 to 3.5 in. pipes (1.27 cm for 7.62 to 8.89 cm pipes)
0.44 in. for 2.5 to 3.0 in. pipes (1.18 cm for 6.35 to 7.62 cm pipes)
0.38 in. for 2.0 to 2.5 in. pipes (0.965 cm for 5.08 to 6.35 cm pipes)
0.32 in. for less than 2.0 in. pipes (0.813 cm for less than 5.08 cm pipes)
FIGURES A.2-A (LEFT) & A.2-B (RIGHT)
3. Remove the paper backing from one foam strip. Place the strip along one of the lines drawn on the
transducer surface. Press the strip down firmly to ensure good adhesion.
Repeat this process again for the second line.
4. To apply coupling compound, press the SIL-GLYDE tube opening against the center of the transducer
(between the foam strips) and provide just enough pressure to apply a thin layer of coupling
compound approximately half the thickness of the foam strip.
Other foam materials may not satisfy performance or safety specifications. Contact
Thermo Fisher when you require more foam strips.
53

APPENDIX B: MODBUS TABLE
B.1
General
The Modbus table defines a limited subset of configuration and run-time variables for the flowmeter.
Regardless of your application, you should first configure the flowmeter using UltraScan. You can set a
Modbus address in UltraScan by accessing the Option tab on the Out/Calibration page. The address
should be between 1 and 254 (0xFE). Address 255 (0xFF) is reserved.
When the flowmeter is started, you can poll basic real-time information such as flow rate, signal level, and
sound speed. The only control to the flowmeter through Modbus is to reset the totalization registers.
