1 INTRODUCTION

1 Introduction

The RMGView diagnostic software supplied with the USM 08 ultrasonic gas meter enables direct

access to the electronic measuring equipment of the ultrasonic gas meter with a standard PC

(system requirements: Windows 2000, XP, 7).

The speed, working memory, and hard drive memory requirements are low. A minimum screen

resolution of 1024 x 768 pixel is necessary for sensible use.

A serial interface is required to connect the USE 09. Standard COM interfaces or USB interfaces

can be used. A converter is necessary for USB and standard COM interfaces (RS 485).

RMGView diagnostic software offers the following functions:

o Selecting all available data from an ultrasonic gas meter with the USE 09

o Automatic recognition of the USE09 software version

o Display of the measurement values and parameters as a list

o Password-protected editing option for the USE09 parameters

o Display of the measurement values as a plot (graphics)

o Creation of user-defined lists

o Creation of user-defined plots

o Option of configuring the USE09 (with the calibration switch open)

o Drafting of test reports

o Graphic diagnostic function

1.1 Installation

If you install a new version of RMGView, it is not necessary to uninstall the old version beforehand.

If you have received the program by email, unzip the zip file in the attachment. Boot the RMGView

installer (version number).exe.

If you have received the program on CD, the CD should start up automatically upon insertion. If

this is not the case, navigate to the CD directory and start the RMGView installer (version

number).exe.

The installer will take you through the next installation steps.

2 USM WINDOW

2 USM window

2.1 "Live values"

Figure 1: Live values

The "live values" dialog box opens as a launch window.

"Live values" is a display designed with several graphic illustrations and in different colors which

displays the status of the meter graphically and with diagrams.

Firstly, configure the COM interface.

To do so, first click on the "Details" button at the upper right.

A new dialog box will open: List - RMGView

2 USM WINDOW

The window appears

Figure 4: Settings: Modbus

First of all, set up the Modbus parameters under "Modbus settings." A physical PC - USM 08

connection must exist to this end. Determine a COM port (system-dependent) and select baud rate

38400, bits-parity-stopbits 8N1, Modbus address 1.

Close the "RMG view list" window by clicking on the cross in the upper right and open "Measuring

element no. xxx" underneath again in the status bar. This will take you back to the "Live values"

launch window.

2 USM WINDOW

We will go into the individual illustrations in this window in detail below:

In the upper left, directly adjacent to the RMG by Honeywell logo, the location (e.g. the station) and

the measuring element number of the ultrasonic meter are displayed.

Figure 5: Location and measuring element information

The content of the AU-1 coordinate is displayed under location according to conventions.

The content of coordinate AU-2 can be found under Measuring element.

Procedure:

Go to the upper right button "Details" in the "Live values" window.

In the upper left you will see "+USM 09 columns"

Click on the + symbol

The list opens with all tables available for the measurement values

At the bottom of the file, click on "AU: user info" and a table into which you can input your data

appears on the right. At the very top you will find

Coordinates

….

The fields with a purple background can be changed at will, dependent on authorizations. This applies to all

tables.

Now enter the name of your location in User text 1.

2 USM WINDOW

Back in the Live Values window, you will find the loaded reference file on the right, adjacent to the

location and the measuring element number. The reference file is the comparative basis for

measurement values (see test protocol). The display for the loaded configuration should be green

("Ok").

RMG View compares the parameters of the connected USM with the parameter set saved in the

pertaining cfg file (measuring element number-cfg) in the background. The result (Ok/Error) is

displayed depending on the configuration.

Figure 7: Reference file and configuration status

The buttons are situated on the right

 "Print Screen" (generates a pdf file of the screen with the date and time)

 "Record 2 min log" (records the data from the meter for 2 minutes, a window opens "Log is

running…," select name for log file and click Ok) and

 "Play back log" (the record stored in the log file is played back with the aid of the RMGView

log player).

2 USM WINDOW

2.2 USM 08 ultrasonic meter:

The ultrasonic gas meter is depicted in a diagram in the lower left. The actual state of the USM 08

is displayed. The measurement electronics, the configuration of the sensors, and the 6 paths can

be recognized. If the measurement electronics are blue, the status of the meter is Ok. This is also

displayed in the graphics on the right. The green color in the small box adjacent to "USE09 status

Ok" shows that the status is fine. If the measurement electronics are red, a red error notification

appears in the same small box (see under "Status displays"). The same applies to the six

measurement paths. These are green in their error-free state and red in the event of errors. If the

cursor arrow is directed onto the path, information on the status can be obtained (see "Detailed

path information"). In the case of error, the cause of the error is also displayed here.

The current gas speed is displayed via the measurement electronics. The blue arrow beneath

states that this measurement is a "forwards" measurement (from left to right). For a "backwards

measurement" (right to left), the arrow is red and points in the other direction.

This information is available for all sensors.

2 USM WINDOW

2.4 Angle of swirl:

The three diagrams adjacent to the meter on the right display the angle of swirl of the three levels.

Ideally, the total of all three angles of swirl should be equal to 0°. If the total of the three angles of

swirl is not equal to 0°, the flow profile is not completely recorded and the measured flow might be

lower or higher than the real flow.

Figure 11: Angle of swirl

2 USM WINDOW

2.5 Status displays:

On the right you will find the status displays for USE 09 and paths 1 to 6.

You can also verify the status displays here from:

AGC (Automatic Gain Control),

(valid reference file necessary)

Swirl,

Profiles,

SNR (Signal-to-Noise Ratio),

SOS (Speed of Sound); deviation from the calculated speed of sound.

Gas quality and operating conditions (inputted under test values) must concur.

%valid (number of valid measurements) displayed.

If everything is fine, the status "Ok" is displayed in green. Where there are error trends, the display

changes to "Warning" in yellow and then to "Error" in red.

Limit values are test values.

In the left section are the measurement values of the gas speed of the levels above, in the center

and below with the 2 respective paths (= 6 paths). The measurement values of the speed ratios of

the levels can be found on the right. This data is compared with the data from the reference file. In

the example, an error notification

error occurs, as the measured value "4.4015" diverges

considerably from the reference value "1.5059", i.e.

192.30%. If the value does not diverge

considerably, a yellow field labeled

Warning appears at the left edge (not available in this sample

protocol).

The measurement values of the swirl angle are depicted on the very right.

D) Efficiency and speed of sound

Figure 58: Test protocol, efficiency and speed of sound section

Here you can see the speed of sound ascertained and the number of valid measurements. The

speed of sound ratio is again compared with the data from the reference file and the percentage

deviation depicted. The

OK field means that the values are all "in the green range."

The speed of sound measured by the USM is compared with the theoretical speed of sound

calculated in accordance with AGA 10 from the gas composition and the operating conditions

(pressure, temperature).

E) Transmitter

The AGC ratios of the individual paths are depicted here compared to the reference file with the

percentage divergence. The signal-noise ratio is depicted on the very right.

Figure 64: RMGView configuration mask

You can set the basic parameters in this window. Several values or units are available to choose

from in each instance.

The AGA 8 calculation tables only exist for the selectable standard pressure and standard

temperature values. Standard pressure and standard temperature cannot therefore be selected

progressively.

The two buttons "Save as default values" and "Discard

changes" relate to the saving or amendment of the inputted

values.

Three other buttons are available:

Figure 75: Other buttons

6.1 "Generate new cfg-file" button

A configuration file of the meter is required for the generation of the USM 08 test protocol with

which current configuration is compared. This should usually reproduce the delivery state or the

data set of calibration or commissioning. A new configuration file can be read out from the meter

electronics with the aid of the "Generate new cfg-file" button and filed in the RMGView "cfg"

subfolder. If data sets need to be provided by external bodies (e.g. high-pressure test benches)

they also need to be stored in the cfg-folder to compare parameters as part of the USM 08 test

protocol generation.

7 TROUBLESHOOTING

7 Troubleshooting

7.1 Reference file is absent

It may happen that RMGView cannot find the reference file the next time it opens due to changes

to units, for example (from ft/s to m/s) and is therefore unable to load.

The reference file is saved in the determined folder under RMGView-K configuration->Configure

folder and can be deleted there.

Click on "Run Inspection" in the "Test values" window.

Ignore an invalid reference file notification.

A log file is created.

Then determine a file name, click on ok and the USM test protocol appears.

Check it.

You are asked whether you want to add the log results to reference files.

Click on "Yes."

It now appears in green writing in the very first line that the reference file was loaded as series

number.ref.

Repeat this procedure for different practice-oriented gas speeds.

The reference file contains the following values for different Vwk:

- C0-C5 (path speed for speed of sound ratio

- AgcUp0…AgcUp5, AgcDown0…AgcDown5: AGC-Level for AGC ratio

- Ve0…2: Level speed for speed ratio

The anticipated value (live values AGC status display, test protocol) is interpolated using Vwk.

The file can also be edited manually by authorized personnel.

7.2 cfg-file is absent

The cfg file should be filed in the cfg folder determined during installation and should also be able

to be called up again from there.

7 TROUBLESHOOTING

7.3 Connection to the meter is disrupted

The notification appears: "You have just removed COM5."

Please check the USB cable connections from the device to the computer. An inadequate USB

plug connection could be responsible for the time out. It could also be caused by an excessively

long or poorly shielded cable. Please only use twisted and shielded cables up to a maximum length

of 500 m. The LiYCX 2 x 2 x 0.75 mm² type is recommended. The green status LED at the bottom

left shows whether communication is error-free.

7.4 "RMGView is already running..." display

The notification appears: "RMGView is already running on COM5."

This means that an instance of RMGView is already running. It cannot be launched a second time

on the same interface.

Troubleshooting: Exit RMGView or, if that is not possible, exit the RMGView.exe process in the

Processes tab in Windows Task Manager (right button on Windows start bar > launch Task

Manager).

However, if connections are desired from the same computer to several ultrasonic gas meters, you

must first change over to the second connected COM port in the already open RMGView before

RMGView can be relaunched on the standard COM port.

7.5 Display "The file USE_112c.rmx …

… was not found. Contact RMG to obtain an appropriate USE_xxx.rmx-file for your USM09."

Obtain the relevant rmx.file for the firmware of your USM09. Disconnect your USM09. Launch

RMGView. Select the menu point.

Open Tools->RMGView APPDATA folder. Copy the .rmx-File into the displayed folder.

Close RMGView. Reconnect your USM09. Launch RMGView.
