Chapter 1. Installation

1.1 Introduction

To ensure safe and reliable operation of the Model XGM868i Ultrasonic Flow Transmitter, the system must be installed in accordance with the guidelines established by GE engineers. Those guidelines, which are explained in detail in this chapter, include the following specific topics:

• Unpacking the Model XGM868i system

• Selecting suitable sites for the electronics enclosure and the flowcell/transducers

• Installing the flowcell/transducers

Note: See the enclosed Transducer Installation Guide for detailed instructions on transducer installation.

• Installing optional temperature and pressure transmitters

• Installing the electronics enclosure

• Wiring the electronics enclosure

WARNING! The Model XGM868i flow transmitter can measure the flow rate of many gases, some of which

are potentially hazardous. In such cases, the importance of proper safety practices cannot be overemphasized.

Be sure to follow all applicable local safety codes and regulations for installing electrical equipment and working with hazardous gases or flow conditions. Consult company safety personnel or local safety authorities to verify the safety of any procedure or practice.

!ATTENTION EUROPEAN CUSTOMERS!

To meet CE Mark requirements, all cables must be installed as described in Appendix A,

CE Mark Compliance.

1.2 Unpacking

Carefully remove the electronics enclosure, the transducers, and the cables from the shipping containers. Before discarding any of the packing materials, account for all components and documentation listed on the packing slip. The discarding of an important item along with the packing materials is all too common. If anything is missing or damaged, contact the factory immediately for assistance.

Chapter 1. Installation

1.3 Site Considerations

Because the relative location of the flowcell and the electronics enclosure is important, use the guidelines in this section to plan the XGM868i installation. Figure 1 shows a typical XGM868i enclosure and spoolpiece ready for insertion into a process line.

Figure 1: A Typical Model XGM868i System

1.3.1 Electronics Enclosure Location

The standard Model XGM868i electronics enclosure is a powder-coated, cast-aluminum, Type-7/4X explosion-proof enclosure; an optional stainless-steel enclosure is available. Typically, the enclosure is mounted as close as possible to the transducers. When choosing a site, make sure the location permits easy access to the electronics enclosure for programming, maintenance and service.

Note: For compliance with the European Union’s Low Voltage Directive (2006/95/EC), this unit requires an external

power disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly visible, directly accessible, and located within 1.8 m (6 ft) of the Model XGM868i.

Chapter 1. Installation

1.3.2 Flowcell Location

The pipeline flowcell consists of the flow rate transducers and any pressure and/or temperature transducers employed as part of the flow measurement system. Ideally, choose a section of pipe with unlimited access to the flowcell; for example, a long stretch of pipe that is above ground. However, if the flowcell is to be mounted on an underground pipe, dig a pit around the pipe to facilitate installation of the transducers.

1.3.3 Transducer Location

For a given fluid and pipe, the Model XGM868i’s accuracy depends primarily on the location and alignment of the transducers. In addition to accessibility, when planning for transducer location, adhere to the following guidelines:

1. Locate the transducers so that there are at least 20 pipe diameters of straight, undisturbed flow upstream and 10 pipe diameters of straight, undisturbed flow downstream from the measurement point. To ensure undisturbed flow, avoid sources of turbulence in the fluid such as valves, flanges, expansions and elbows; and dips or low spots in which condensed liquid may collect.

2. Because condensate or sediment at the bottom of the pipe may cause attenuation of the ultrasonic signal, locate the transducers on the side of a horizontal pipe, when possible. If limited pipe access necessitates top-mounted transducers and the sound beam path includes a reflection, shift the transducers to at least 10° off top dead center. This will minimize the influence of any sediment on the reflected ultrasonic signals.

1.3.4 Cable Lengths

Locate the electronics enclosure as close as possible to the flowcell/transducers, preferably directly on the flowcell. However, the factory can supply transducer cables up to 1,000 ft (300 m) in length for remote location of the electronics enclosure. If longer cables are required, consult the factory for assistance.

1.3.5 Temperature and Pressure Transmitters

When installing temperature and/or pressure transmitters in the flowcell, locate them downstream of the transducers. These transmitters should be positioned no closer to the Model XGM868i transducers than 2 pipe diameters and no further away from the transducers than 20 pipe diameters.

1.3.6 Transducer Cables

When installing the transducer cables, always observe established standard practices for the installation of electrical cables. Specifically, do not route transducer cables alongside high-amperage AC power lines or any other cables that could cause electrical interference. Also, protect the transducer cables and connections from the weather and corrosive atmospheres.

Note: When using non-GE cables to connect the flow rate transducers to the Model XGM868i electronics enclosure,

the cables must have electrical characteristics identical to the GE cables. Type RG62 a/u coaxial cable should be used, and each cable must be the same length (within ±4 in.).

A flowcell is the section of pipe where the transducers are mounted. It can be created either by mounting the transducers on the existing pipeline or by mounting them on a spoolpiece. A spoolpiece is a separately manufactured pipe section, matched to the existing pipe, which contains ports for mounting the transducers. This approach allows the transducers to be aligned and calibrated before inserting the spoolpiece into the pipeline.

Figure 1 on page 2 shows a typical Model XGM868i spoolpiece, with a mounting bracket to hold the electronics enclosure. For detailed instructions on installing the transducers and/or spoolpiece, refer to the supplied drawings and the enclosed GE Gas Transducer Installation Guide (916-049).

1.5 Installing Temperature and Pressure Transmitters

Optional temperature and pressure transmitters may be installed near the ultrasonic transducer ports as part of the flowcell. Be sure to observe the siting requirements given earlier in this chapter. These transmitters should send a 0/4-20 mA signal to the Model XGM868i. In turn, the Model XGM868i must be fitted with a suitable option card to process the signals and to provide the required 24 VDC power to the transmitters. Any desired transmitters or sensors may be used, but they must have an accuracy equal to 0.5% of the reading or better.

Note: Resistive Thermal Devices (RTDs) are a good choice for measuring the temperature.

Typically, a 1/2” or 3/4” NPT female threaded port is used to mount the transmitters on the flowcell. If the pipeline is insulated, the coupling may need to be extended to provide convenient access. Of course, other types of mounting ports, including flanged ports, may be used for the transmitters.

Figure 2 shows a typical mounting arrangement for the pressure and temperature transmitters. The temperature sensor should protrude 1/4 to 1/2 way into the pipe.

1.7.5h Wiring the MODBUS Option Card

The MODBUS option card uses the RS485 standard for MODBUS communication. The MODBUS card must be installed in Slot 2. The RS485 standard allows up to 32 nodes (drivers and receivers) on one multidrop network, at distances up to 4,000 ft (1,200 m). GE recommends using 24-gauge (24 AWG) twisted-pair wire with a characteristic impedance of 120 ohms and 120-ohm termination at each end of the communications line.

Note: The MODBUS option card provides its own RS485 connections. Thus, the meter can have its serial port

configured as RS232 and still provide RS485 MODBUS signals.

IMPORTANT: Because the MODBUS option card uses pins 1 and 2 on terminal block J2, only those option cards that do

not use these pins may be installed in Slot 1, while a MODBUS card is installed in Slot 2. Specifically, only the option cards designated as “OI” and “OR” in Figure 11 on page 26 are compatible with the MODBUS option card.

Chapter 2. Initial Setup

2.1 Introduction

This chapter provides instructions for programming the minimum amount of data required to place the Model XGM868i flowmeter into operation. Before the Model XGM868i can begin taking measurements and displaying valid data, the current system and pipe parameters must be entered. In addition, a 2-Channel meter requires that each channel be activated prior to use. Additional programming options provide access to the more advanced features of the Model XGM868i, but this information is not required to begin taking measurements.

Refer to the Programming Manual for information on programming all other features. Be sure to record all programming data in Appendix B, Data Records.

As a guide in following the programming instructions in this chapter, the relevant portions of the Model XGM868i menu map have been reproduced in Figure 15 on page 41.

2.2 Programming Methods

Note: See the Programming Manual for information on those User Program features not covered in this chapter.

You can program the XGM868i via either the keypad on the lower part of the glass enclosure, or PanaView™, a PC-based, non-resident software program that communicates with the XGM868i via its RS232 serial port. PanaView supplements basic XGM868i functions with several additional capabilities. With PanaView, you can:

• load and save site file data

• create and save graph and log files

• display text output and graphs of live measurement data

• create custom templates for displaying text, graph and log data

• interface with multiple GE instruments.

This chapter focuses on programming via the keypad. For information on programming the XGM868i via PanaView, refer to Appendix C of the Programming Manual.

Chapter 2. Initial Setup

2.3 The XGM868i Enclosure Keypad

Keypad Program

Along with the 2-line, 16-character LCD, the XGM868i includes a 6-key magnetic keypad. The decal cutout for each

key contains a hall effect sensor, pushbutton switch and visible red LED. The magnetic wand used to activate a magnetic key is found attached to the meter chassis below the front panel. An operator activates the key by pressing the magnetic wand up to the glass lid over the desired key. The LED will light indicating a successful key press.

Note: The pushbutton switch will also act as a key press but is done with the glass lid open. Do not use the

pushbutton switch in a hazardous area where the lid needs to be installed.

Use the magnetic keypad to navigate through the user program. The menu map may be followed in sequence, or the four arrow keys may be used to scroll through the prompt screens. Figure 14 shows the front of the XGM868i, with magnetic keypad and magnetic wand.

Magnetic Wand

Figure 14: XGM868i Magnetic Keypad and Wand

IMPORTANT: The XGM868i’s keypad enables programming of the instrument through the glass faceplate without

removing the cover. Thus, all programming procedures may be performed while the unit is installed in a hazardous area.

Six keys on the keypad enable users to program the XGM868i:

• [Enter] - confirms choice of a specific option and data entry within the option

• [Escape] - allows users to exit from a specific option without entering unconfirmed data

• [] and [] - enable users to view a specific measurement in the Key display setting or to scroll through a list of

options (letters and numbers 0-9 as well as the negative sign and decimal point) in a menu

• [] and [] - enable users to scroll to a specific option, among choices in an option, or to a character in a text

entry.

Because the Model XGM868i does not have an ON/OFF switch, it will power up as soon as the connected power source is energized.

Note: For compliance with the European Union’s Low Voltage Directive (2006/95/EC), this unit requires an external

power disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly visible, directly accessible, and located within 1.8 m (6 ft) of the Model XGM868i.

There are three methods for obtaining readings from the XGM868i:

• Built-in LCD display

• PanaView software on a computer

• Device to read the XGM868i’s analog output

At least one of the above display options must be installed in order to obtain flow rate readings from the meter.

Immediately upon power up the software version display appears. Then, the meter performs a series of internal checks, which take about 45 seconds, prior to displaying the flow rate data.

Note: If the Model XGM868i fails any of the internal checks (see Chapter 2, Error Codes, in the Service Manual), try

disconnecting the power and then repowering the unit. If the meter continues to fail any of the internal checks, contact the factory for assistance.

After successfully performing the internal checks, the Model XGM868i begins taking measurements and the software version display is replaced by a measurement mode display. Proceed to the appropriate section for instructions on using the LCD display and the PanaView display option.

Note: As a minimum, the system and pipe parameters (for each installed channel of a 2-channel meter) must be

entered before the Model XGM868i can display valid data. Refer to Chapter 2, Initial Setup, for specific instructions.

Appendix C. Measuring P and L Dimensions

C.1 Introduction

When programming the PIPE menu in the Model XGM868i’s User Program, the path length (P) and the axial dimension (L) must be entered. These parameters are determined by measurements on the actual transducer

installation, with P equal to the face-to-face distance between the transducers and L equal to the axial distance between the centers of the transducer faces.

The accuracy of the programmed P and L values is critical to precise flow rate measurements. If GE supplies the flowcell for the system, the correct values will be included in the documentation supplied with the system. For transducers installed on an existing pipe (see Figure 22 on page 70), P and L must be measured at the site. This appendix provides instructions for properly determining these dimensions.

C.2 Measuring P and L

Whenever possible, physically measure the face-to-face distance (P) and the axial distance (L) between the centers of the flat faces of the transducers. Refer to Figure 22 on page 70 for an illustration of the proper distances to measure, in a typical installation.

In some situations only one of the required distances can be directly measured. When this happens, a knowledge of the installation angle () of the transducers, permits the second distance to be calculated from Equation C-1

cos

---= P

As an example, assume that the transducer installation angle is known to be 45° and the L distance is measured to be

10.00 inches. Then, the P distance is calculated to be P = 10.00/0.707 = 14.14 inches.

With a Bias 90° transducer installation, it sometimes happens that the only known parameters are the transducer angle

() and the centerline distance between the transducer bodies (CL). In these cases, it is still possible to calculate P and L by combining Equation C-1 with the additional Equation C-2 (see Figure 22 on page 70):

P CL 1.2–=

Standard GE 90° transducers have the face offset from the centerline of the body by 0.6 inches. Thus, a pair of

transducers has a total offset of 1.2 inches, as indicated in Equation C-2. For example, suppose that the transducer installation angle is 30° and CL is measured to be 12.00 inches. Then, P = 12.00 – 1.2 = 10.80 inches and L = 10.80 x

0.866 = 9.35 inches.
