vi DigitalFlow™ XMT868i Startup Guide

Chapter 1. Installation

1.1 Introduction

To ensure safe and reliable operation of the Model XMT868i Flow Meter, the system must be installed in accordance with the guidelines established by GE engineers. Those guidelines, explained in detail in this chapter, include the following topics:

• Unpacking the Model XMT868i system

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

• Installing the flowcell/transducers

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

• Installing optional temperature transmitters

• Installing the electronics enclosure

• Wiring the electronics enclosure

WARNING! The Model XMT868i flow transmitter can measure the flow rate of many fluids, some

potentially hazardous. The importance of proper safety practices cannot be overemphasized.

WARNING! Be sure to follow all applicable local safety codes and regulations for installing

electrical equipment and working with hazardous fluids or flow conditions. Consult company safety personnel or local safety authorities to verify the safety of any procedure or practice.

WARNING! 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.

DigitalFlow™ XMT868i Startup Guide 1

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 XMT868i installation. Figure 1 below shows a typical installation.

Figure 1: A Typical Model XMT868i System

1.3.1 Electronics Enclosure Location

The standard Model XMT868i electronics enclosure is a powder-coated, cast-aluminum, Type-7/4X explosion-proof enclosure, and 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, 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 unit.

1.3.2 Flowcell Location

Ideally, choose a section of pipe with unlimited access; 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.

Chapter 1. Installation

1.3.3 Transducer Location

For a given fluid and pipe, the Model XMT868i’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:

• Locate the transducers so that there are at least 10 pipe diameters of straight, undisturbed flow upstream and

5 pipe diameters of straight, undisturbed flow downstream from the measurement point. Undisturbed flow means avoiding sources of turbulence in the fluid such as valves, flanges, expansions, and elbows; avoiding swirl; and avoiding cavitation.

• Locate the transducers on a common axial plane along the pipe. Locate the transducers on the side of the pipe,

rather than the top or bottom, since the top of the pipe tends to accumulate gas and the bottom tends to accumulate sediment. Either condition will cause increased attenuation of the ultrasonic signal. There is no similar restriction with vertical pipes. However, vertical pipes should be avoided in order to insure a full pipe at the measurement point.

1.3.4 Cable Lengths

Locate the electronics enclosure as close as possible to the flowcell/transducers, preferably directly on the flowcell. However, GE 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 Transducer Cables

When installing the transducer cables, always observe established standard practices for the installation of electrical cables. 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: If you are using your own cables to connect the transducers to the electronics console, they must have

electrical characteristics identical to the cables supplied by GE. For transducer frequencies up to 2 MHz, the cables in each pair must be the same length within ±4 in. (10 cm). For transducer frequencies above 2 MHz, the cables in each pair must be the same length within ±0.5 in. (1.25 cm).

1.4 Installing a Flowcell

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 XMT868i 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 appropriate Transducer Installation Guide.

1.5 Installing Temperature Transmitters

Optional temperature transmitters may be installed as part of the flowcell, near the ultrasonic transducer ports. 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 XMT868i. In turn, the XMT868i 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” 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 below shows a typical mounting arrangement for a temperature transmitter. The temperature transmitter 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 multi-drop 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 24 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 XMT868i flow meter into operation. Before the Model XMT868i 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 XMT868i, but this information is not required to begin taking measurements.

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

You can program the XMT868i using either the keypad on the lower part of the glass enclosure, or PanaView™, a PC-based, non-resident software program that communicates with the XMT868i using its RS232 serial port. PanaView supplements basic XMT868i 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 using the magnetic keypad. For information on programming the XMT868i using PanaView, refer to Appendix C of the Programming Manual.

2.2 XMT868i Enclosure Keypad Program

Along with the 2-line, 16-character LCD, the XMT868i 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 cover removed. Do not use the

pushbutton switch in a hazardous area where the glass cover needs to be in place.

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 13 below shows the front of the XMT868i, with magnetic keypad and magnetic wand.

Figure 13: XMT868i Magnetic Keypad and Wand

The following six keys on the keypad enable users to program the XMT868i:

• [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 highlight a specific window in the display option or to scroll through a list of

options (parameters, 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.

When you power up the XMT868i, the display first shows the model name and software version:

Chapter 3. Operation

3.1 Introduction

See Chapter 1, Installation, and Chapter 2, Initial Setup, to prepare the Model XMT868i system for operation. When the meter is ready to take measurements, proceed with this chapter. The following specific topics are discussed:

• Powering Up

• Using the Display

• Taking Measurements

• Pausing Measurement

Note: All inputs and outputs of the Model XMT868i are calibrated at the factory, prior to shipment. If it becomes

necessary to recalibrate any of the inputs and/or outputs, see Chapter 1, Calibration, of the Service Manual for instructions.

WARNING! To ensure the safe operation of the Model XMT868i, it must be installed and operated

as described in this manual. In addition, be sure to follow all applicable local safety codes and regulations for the installation of electrical equipment.

DigitalFlow™ XMT868i Startup Guide 47

Chapter 3. Operation

3.2 Powering Up

Because the Model XMT868i 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, 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 unit.

There are three methods for obtaining readings from the XMT868i:

• Built-in LCD display

• PanaView software on a computer

• Device to read the XMT868i’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.

CAUTION! The XMT868i conducts the FRAM (non-volatile RAM) test only on the first powering

up. If the screen displays the message, “Program Memory Fault Detected,” consult the factory immediately. Otherwise, the XMT868i will not repeat the test and may not properly save programmed values.

Note: If the Model XMT868i fails any of the internal checks (see Chapter 2, Error Codes, in the Service Manual), try

disconnecting the power and then re-powering 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 XMT868i 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 XMT868i can display valid data. Refer to Chapter 2, Initial Setup, for specific instructions.

Appendix C. Measuring P and L Dimensions

C.1 Measuring P and L

If you are using wetted transducers, the XMT868i requires you to enter the path length (P) and the axial dimension (L),

P is the transducer face-to-face distance and L is the axial projection of P in the flow stream.

where

To determine in Figure 22 below, if possible. If such a measurement is not possible, consult the factory.

L, physically measure the distance between the center of the transducer ports at the inside wall as shown

To determine

• Pipe inside diameter (ID)

• Wall thickness (WT)

• Installed pipe coupling length (CL)

• Transducer face depth (FD)

• Mounting angle (MA)

DigitalFlow™ XMT868i Startup Guide 75

Figure 22: 180

P, you need to know the following:

Transducer Installations - Top View

Appendix C. Measuring P and L Dimensions

MA = 45°

C.1 Measuring P and L (cont.)

Use Figure 23 below to properly measure the coupling length. Typically, the transducer face is positioned just outside the inside diameter (ID) of the pipe or slightly retracted inside the coupling.

Figure 23: Determining the Pipe Coupling Length

Use the following formula to determine the P dimension:

[ID + 2(WT)]/(cos MA) + 2(CL) - FD) = P Dimension

For example, given the following:

• Inside diameter (ID) = 48”

• Wall thickness (WT) = 3/8”

• Installed coupling length (CL) = 2.0”

• Transducer face depth (FD) = 1.75”

• Mounting Angle (MA) - 45

The P dimension would be [48 + 2(3/8)]/(0.7071) + 2(2.0 - 1.75) = 69.4”
