SECTION 3.0: INSTALLATION

3.1 OVERVIEW

Each F-4300 Ultrasonic Flow Meter is provided with a pair of matched ultrasonic transducers. The transducers are mounted (clamped) on to the outside wall of the pipe. Triaxial cables convey the transducer signals to the wall mount enclosure containing the signal processing circuitry and the user interface display. Ultrasonic transducers can be congured to operate in either 4, 2 (Reect) or 1 (Direct) cross operating modes. The choice of operating mode is dictated by the conguration settings programmed into the meter. For new installations, conguration data is programmed into the meter prior to shipment. Programming data determines the transducer operating mode and the spacing between the transducers. This information is provided with the installation hardware in a document titled, “F-4300 Site Installation Details”.

1 Cross Z or (Direct)

2 Cross V or (Reect)

4 Cross W or (Double Reect)

4 or 2 Cross Mode (Reect)

4 or 2 cross mount is the recommended operating mode whenever possible. It is the simplest way to mount the transducers. Operating in the reect mode also minimizes the effects of some ow distortions.

1 Cross Mode (Direct)

1 cross mount provides a shorter sonic beam path. This usually improves performance with sonically attentive liquids or pipe materials. Direct mounting only requires half the distance between electrodes when compared to the reect mode and may be the only option if the availability of mounting space is limited.

3.2 SITE SELECTION

Careful attention to the site selection for the system components will help the installers with the initial installation, reduce start-up problems and make future maintenance easier. For example, do not install the meter where it will be difcult for personnel to perform periodic maintenance. When selecting a site for mounting the system components, consider the criteria under Section

1.7 WORKING ENVIRONMENT, as well as the following:

The Wall-Mount Enclosure

Find an easily accessible location where wire connections can be made and meter readings can be taken from oor level. Mount the enclosure on a vibration-free surface. Avoid sites such as the plenum of a fan coil, heat exchanger, or other housings containing motors. Avoid mounting the enclosure in close proximity to VFD’s, electric motors or other strong sources of electrical interference.

The maximum allowable distance between the wall-mount enclosure and the transducers installed on the pipe is 100 feet. Only ONICON furnished cable may be used between wall-mount enclosure and the transducers.

F-4300 Series Clamp-on Ultrasonic Flow Meter Manual 06/17 - 2056-2 / 37515 Page 10

IMPORTANT NOTE

The Transducers

For best results, the transducers must be installed on a straight run of pipe, free of bends, tees, valves, transitions, insertion probes and obstructions of any kind. For most installations, ten straight unobstructed pipe diameters upstream and ve diameters downstream of the transducers is the minimum recommended distance for proper operation. Additional considerations are outlined below.

IMPORTANT NOTE

In some cases, longer straight runs may be necessary where the transducers are placed downstream from devices which cause unusual ow prole disruptions or swirl; for example, modulating valves or two elbows in close proximity and out of plane, etc.

Flow

10 Dia.

• Do not, if possible, install the transducers downstream from a throttling valve, a mixing tank, the discharge of a positive displacement pump or any other equipment that could possibly aerate the liquid. The best location will be as free as possible from ow disturbances, vibration, sources of heat, noise, or radiated energy.

• Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale, rust, loose paint, etc., from the location prior to mounting the transducers.

• Do not mount the transducers on a surface aberration (pipe seam, etc.).

• Do not mount transducers from different ultrasonic ow meters on the same pipe.

• Do not run the transducer triaxial cables in common bundles with cables from other instrumentation. You can run these cables through a common conduit ONLY if they originate at the same ow meter.

• Never mount transducers under water.

• Avoid mounting transducers on the top of a horizontal pipe. The best placement on a horizontal pipe is either the 10:00 or 2:00 position for 4 or 2 cross mode (Reect), or one sensor at 9:00 and one sensor at 3:00 for 1 cross mode (Direct).

• Do not mount transducers on the bottom of a horizontal pipe.

• Mounting on a vertical pipe is recommended only if ow is in the upward direction. When mounting on a vertical pipe owing in a downward direction, make sure there is sufcient back pressure in the system to maintain a full pipe.

5 Dia.

IMPORTANT NOTE

3.3.1 Mounting the Enclosure

Find an easily accessible location where electrical connections can be made and meter readings can be taken from the oor level. Mount the enclosure on a vibration-free surface. Avoid sites such as the plenum of a fan coil, heat exchanger, or other housings containing motors. Avoid mounting the enclosure in close proximity to VFD’s, electric motors or other strong sources of electrical interference.

Do not drill additional holes in this enclosure. Doing so may damage the electronic circuitry contained within and will void all warranties.

CAUTION

3.3.2 Preparing the Pipe

Once a suitable section of straight pipe has been located, the pipe surface must be prepared. Refer to the Site Installation Details document provided with the installation hardware to determine the transducer spacing dimensions. Prepare the pipe surface as shown below. Clean and de-grease two rectangles where the transducers will be located. Use sand-paper as necessary to remove any grit, corrosion, rust, loose paint or other contaminants. The cleaned surface should extend at least ½” beyond the length and width of the transducers.

Always install hardware at the 10:00 or 2:00 position on horizontal pipes. This prevents the ow meter from being affect by air trapped at the top of the pipe.

Refer to site installation details document for transducer spacing.

Prepare mounting locations for transducers.

For horizontal pipes, locate transducers at the 10:00 or 2:00 position.

3.3.3 4 or 2 Cross Mode (Reect) Mounting Using Frames and Spacer Bar

1. Prepare the pipe surface as described in section 3.3.2.

2. On a at surface, assemble the hardware as shown in the drawing below.

Orient mounting brackets as shown.

Space bar shows distance

between transducers

Reference Position

3. Install the mounting straps as shown below. For larger pipes, use multiple straps connected end-to-end to increase the length of each strap. Leave enough slack in the straps to allow the assembly to be correctly positioned on the pipe. The location of the routing hole allows for the straps to mount outside of the pipe insulation, if the pipe is insulated.

Refer to the Site Installation Details document provided with the installation hardware to determine the correct separation distance.

Routing Holes

4. Move the hardware assembly to its nal position on the pipe. Align the brackets with the prepared surface for each transducer, ensuring that the entire assembly is properly oriented along the axis of the pipe. Tighten the assembly rmly on the pipe. Do not over tighten the straps.

Wrap the rst mounting strap around the pipe and through the

holes of the side of the mounting bracket. Make sure to position it so there is easy access to the adjustment screw. Repeat this procedure for the second mounting bracket.

Adjustment Screw

3.3.4 1 Cross Mode (Direct) Mounting Using Brackets and Spacer Bar

1. Once the installation site selection process described in section 3.2 is complete, prepare the pipe where the rst sensor will be mounted.

IMPORTANT NOTE

1 Cross mode mounting requires that transducers be installed on opposite sides of the pipe. For horizontal pipes, the transducers should be located at the 3 o’clock and 9 o’clock positions.

2. To prepare the pipe, temporarily position a mounting bracket on the pipe where you will be mounting it. Ensure that the pipe surface is smooth without any raised areas (seams, etc.) With a pencil, marker or chalk, draw a generous rectangle around the bracket. Clean and de-grease the area within the rectangle. Use the small sanding block provided with the installation hardware as necessary to remove any grit, corrosion, rust, loose paint or other contaminants. Be sure to wipe the surface clean after sanding. The cleaned surface should extend at least ½” beyond the length and width of the mounting bracket.

3. Attach the spacer bar to one of the mounting brackets at the reference mark on the ruler.

4. Position the mounting bracket and spacer bar in the center of the cleaned area and secure it in place with a mounting strap as shown below. Make sure the mounting strap tightening screw is facing up. While tightening the strap, check to ensure that the bracket remains centered on the pipe. (The bracket is centered on the pipe when the bottom edges of both stainless side plates on the bracket are in full contact with the pipe surface.)

5. Attach the second bracket to the spacer bar at the separation distance specied on the site installation details document provided with the installation hardware.

Orient mounting brackets as shown.

Reference Hole

6. Check to ensure that this bracket is lined up on the center of the pipe. While holding the bracket centered on the pipe, place a mark (with pencil or chalk) at the center of the bottom of the bracket as shown below. Next, mark along the edge of the bracket as indicated in the drawing below.

Place mark at center of bracket roller.

7. Remove the bracket from the spacer bar and then remove the spacer bar from the bracket that is strapped to the pipe. Using the spacer bar as a straight edge, draw a line down the center of the pipe intersecting the mark made at the center of the tapered roller and the line drawn against the edge of the bracket as shown below.

Spacer bar

Draw line using spacer bar as edge.

8. Wrap a spacing guide (could be a wire, hose clamp) around the pipe so that the left edge is against the

transducer edge mark. Arrange so that one end overlaps the other. Ensure that it is snug around the pipe and mark along the overlapping edge.

Spacing guide

Draw the guide tightly around the pipe and mark at the overlapping edge.

9. Remove the spacing guide and lay it out on a at surface. Either measure the exact distance half-way between the overlap edge and the mark at the overlap, or fold the guide from the overlap edge to overlap mark and draw a line at the fold or halfway point.

50%

Overlap edge mark

10. Reinstall the spacing guide; its edge abutting the bracket edge mark on the pipe and the overlapping edge in line with the line drawn down the center of the pipe. Tape it in this position on the pipe. Take the second bracket and place it against the edge of the guide with it centered on the half way mark drawn on the guide.

11. Ensure that the bracket is sitting on a smooth area without any raised spots (seams, etc.). Mark a generous rectangle around the bracket with a pencil, marker or chalk. Remove the bracket and the spacing guide.

12. Clean and de-grease the area within the rectangle. Use the small sanding block provided with the installation hardware as necessary to remove any grit, corrosion, rust, loose paint or other contaminants. The cleaned surface should extend at least ½” beyond the length and width of the mounting bracket.

13. Replace the spacing guide back in the same position it was in and re-tape it to the pipe.

14. Position the bracket as before against the edge of the guide with the center of the bracket centered on the half way mark drawn on the guide. Secure it in place with a mounting strap. Make sure the mounting strap tightening screw is facing toward the bracket so you can hold it in place while tightening the screw. While tightening the strap, check to ensure that the bracket remains centered on the pipe. (The bracket is centered on the pipe when the bottom edges of both stainless steel side plates on the bracket are in full contact with the pipe surface.)
