SECTION 1: PRODUCTINFORMATION

1.1 Introduction

We appreciate your business and your choice of Welker products. The installation, operation, and maintenance liability for this equipment becomes that of the purchaser at the time of receipt. Reading the applicable Installation, Operation, and Maintenance (IOM) Manuals prior to installation and operation of this equipment is required for a full understanding of its application and performance prior to use.*

If you have any questions, please call Welker at 1-281-491-2331.

*The following p roced ures have been written for use with standard Welker pa rts and eq uipment. Assemblies that have been modified may have additional

requirements and specifications that are not listed in this manual.

1.2 Product Description

The Welker PP-1, PP-2, PP-3, and PP-F Pitot Probes are designed to create a product loop through a connected sampler or sampling system.

When the product outlet and return of the unit are connected to a sampler or sampling system, the circulation pump and/or kinetic energy from flow velocity create a circulation loop, a.k.a. hot loop. When in operation, product circulates through the hot loop, continually presenting fresh product to the sampler or sampling system, allowing for collection of representative samples.

Welker may custom design the PP-1, PP-2, PP-3, and PP-F to suit the particular application and specifications of each customer.

SECTION 2: INSTALLATION&OPERATION

2.1 Before You Begin

After unpacking the unit, check the equipment for compliance and any damage that may have occurred during shipment. Immediately contact a Welker representative if you received damaged equipment.



When sealing fittings with PTFE tape, refer to the proper sealing instructions for the brand used.



1. For sampling applications, Welker recommends that the unit be inserted into the center one-third (¹⁄₃) of the pipeline in

a location where the product is well-mixed and will yield an accurate and representative sample. 2. For gas sampling applications, Welker recommends that the unit be installed in the top of the pipe. 3. For liquid sampling applications, Welker recommends that the unit be installed in the side of the pipe. 4. For liquid sampling applications, locate the unit two to four pipe diameters (2–4D) downstream of an inline static mixer

or other flow conditioning system. 5. Handle the unit with care.

2.2 Installation and Operation

1. Depressurize the pipeline.



The pipeline must be depressurized prior to installing and removing the unit.



2.

As necessary, install valves to the pipeline connection (Figure 1). One will be product outlet (P₁) valve A, and the other

will be product return (P₂) valve B.

3.

Ensure that product outlet (P₁) valve A and product return (P₂) valve B are closed (Figure 2, Figure 3, or Figure 4). As

necessary, cut off excess tubing from the probe. Using tubing cutters, remove the excess tubing, and then file and

smooth the cut edge of the probe.

4. If the probe tip is scooped or beveled, determine the direction of product flow in the pipeline. For the Pitot Probe to

function correctly, it must be installed so that the scooped probe tip is open against the direction of product flow.



If applicable, refer to the flow direction stamped on the pipeline connection or handle to determine correct orientation before installing the Pitot Probe to the pipeline.



5. If the Pitot Probe has an MNPT pipeline connection, continue to step 6. If the Pitot Probe has a flanged pipeline

connection, proceed to step 9.

11

MNPTPipeline Connection

6. Wrap the threads of the threaded pipeline connection with PTFEtape. 7. Install the Pitot Probe to the mating connection on the pipeline and tighten. 8. Proceed to step 14.

Flanged Pipeline Connection

9. Position an appropriately sized gasket on the mating flange connection. 10. Install the Pitot Probe to the mating flange connection. 11. Following a cross-bolting sequence, install bolts and nuts to the flanges. 12. Tighten all bolts to the appropriate torque. 13. Continue to step 14.

Completing Installation

14. Pressurize the pipeline and check for leaks. 15.

Use appropriately sized tubing to connect from product outlet (P₁) valve A to the customer equipment (Figure 2, Figure 3, or Figure 4).

16.

Use appropriately sized tubing to connect from the customer equipment to product return (P₂) valve B (Figure 2, Figure 3, or Figure 4).

17.

Open product outlet (P₁) valve A and product return (P₂) valve B to begin operation (Figure 2, Figure 3, or Figure 4).

2.3 Removing the Pitot Probe

1. Depressurize the pipeline.



The pipeline must be depressurized prior to installing and removing the unit.



2.

Close product outlet (P₁) valve A and product return (P₂) valve B (Figure 2, Figure 3, or Figure 4). 3. Disconnect customer equipment from the outlet and return. 4. Remove the Pitot Probe from the pipeline.

3.1 Before You Begin

SECTION 3: MAINTENANCE

1.

Maintenance is necessary if a leak occurs at one or both valves.

2. Prior to maintenance or disassembly of the unit, it is advisable to have a repair kit available for repairs of the system in

case of unexpected wear or faulty seals.



New seals supplied in spare parts kits should be lightly lubricated before being installed to ease the installation of the seals and reduce the risk of damage when positioning them on parts. Wipe excess lubricant from the seals, as it may adversely affect analytical instrument results.



For sample-exposed seals, Welker recommends non-hydrocarbon-based lubricants, such as Krytox®. For non-sample-exposed seals, Welker recommends either non-hydrocarbon-based lubricants or silicone-based lubricants, such as Molykote® 111.



After the seals are installed, the outer diameter of shafts and inner diameter of cylinders may be lubricated to allow smooth transition of parts.

 3. All maintenance and cleaning of the unit should be performed on a smooth, clean surface.

4. Welker recommends having adjustable wrenches available for maintenance. Please note that the exact tool required

may vary by model.

3.2 Maintenance

Maintenance is needed when a leak occurs at product outlet (P₁) valve A and/or product return (P₂) valve B.



 1.

Prior to performing maintenance, the Pitot Probe must be removed from the pipeline. See Section 2.3, Removing the

Pitot Probe, for instructions on removing the Pitot Probe from the pipeline. 2.

Unscrew product outlet (P₁) valve A and/or product return (P₂) valve B from the pipeline connection (Figure 2, Figure 3,

or Figure 4). 3.

To perform maintenance on product outlet (P₁) valve A and/or product return (P₂) valve B, refer to the Installation,

Operation, and Maintenance (IOM) Manual for the valve(s). 4. As necessary, clean the probe. 5.

Install product outlet (P₁) valve A and/or product return (P₂) valve B to the pipeline connection (Figure 2, Figure 3, or

Figure 4). 6.

Maintenance is now complete. Reinstall the Pitot Probe according to the instructions in Section 2.2, Installation and

Operation.



Check valves for leaks and repair as necessary during reinstallation.

3.3 Troubleshooting

Issues Possible Causes Solutions

Product outlet (P₁) valve A and/or product return (P₂) valve B is leaking.

Table 5: Pitot Probe Troubleshooting

There is debris in the valve.

The valve O-rings and/or seat are worn or damaged.

Maintain the valve. Refer to the Installation, Operation, and Maintenance (IOM) Manual for the valve for maintenance instructions.
