2. PRE-OPERATION

Before you can start the operation of the Winscreen program, the program must be installed.

2.1. Install Winscreen Software

A.

Insert the installation floppy disc or CD-ROM in the PC or locate the

Winscreen installer (Winscreen.msi).

B.

Double-click the Winscreen installer.

C.

Follow the on-screen instructions.

2.2. Uninstall Winscreen Software

A.

Go to Start, Settings, Control Panels, Add/Remove Programs

B.

Find Winscreen in the program list. Click the Remove button.

C.

Follow the on-screen instructions.

2.3. Set the IP address on the PC (Ethernet only)

To communicate with the meter, the IP address of the meter must be reachable from the PC (on the same subnet). This rule applies to any networked unit. The

IP address of the PC can be checked by running “IPCONFIG” in a DOS box. If the PC and the meter are on different subnet, one of them needs to change the

IP address. If the meter is not connected on a network with a DHCP server, you can change the IP address of the PC. If you are on a network with a DHCP server, extreme care should be taken so that you do not select the same IP address as another unit on the network. Please contact your network administrator in any cases if in doubt.

To change the IP address of your PC:

A.

From the Star menu in Windows, select

Settings – Network and Dial-up

Settings – Local Area Connection

.

B.

Select

TCP/IP protocol - Properties

.

C.

Set a fixed IP address (

Specify IP address

) and set an address in the same group as the flow meters (but not the same), for example 128.1.200.100.

(Meter address in this example is 128.1.200.54).

D.

Set subnet mask 255.255.255.0. The first three digits, in the IP address must the be equal for the PC to reach the meter

NOTE: Each IP address must be unique, i.e. no units connected to the same network can have the same IP-address.

3.1. Connecting to the Ultrasonic Meter

3.1.1. First time communication setup

Each meter on the network will have a unique IP-address. The IP-address and name of the meter can be defined in the Host-file on the PC to simplify access.

For editing the Host file, do the following steps:

A.

Click on the soft key “Define a new target” in the picture shown below.

B.

Then the Host file appears and can be updated with correct IP-address and name of the meter.

Note: Use the space key, not the TAB-key for spacing.

MNKS002 0.0 (4/08)

MPU Series B


3.1.3. Establish communication with serial link

This section describes how to establish data communication with a serial connection (RS-485/422/232) between the flow meter and the PC.

The WinScreen program can be run using serial communication with one single meter or a multidrop network with multiple meters. The meter is designed to communicate through both Ethernet and serially via Modbus. The

PC has RS232 interface, meaning if RS485 or RS422 is used due to long cable lengths, a converter to RS232 is required.

A.

Connect a 9-pin serial cable to the PC’s serial port (usually COM1)

B.

Connect cable to the meter’s serial port. Refer to the wiring diagram in the

User’s Manual.

C.

Start Winscreen. Select COM1 from the pull-down menu.

D.

Click the “Connect to meter” soft key.

3.2. Run Winscreen against PC Simulator

For demonstration or training purposes, the Winscreen program can run a meter simulator included in the application. Select “Simulator Ultra6”,

“Simulator MPU1200”, “Simulator MPU600” or “Simulator MPU200” in the

“Meter name” field as shown above, and click on the “Connect”-button. If the

“Measured values” window is opened, the measurement data can be inspected as if the Winscreen program was connected to a real meter with flow. Each piece of data can be manipulated under the Manual Values tab of the Database

Configuration screen.

To simulate flow select from the main menu:

Tools – Simulator – Simulate Transit times. (See chapter 6 for more detail on simulation.)

3.3. Trouble Shooting – Ethernet

If no contact to the meter is obtained:

•

Check that the power on the meter is switched on.

•

Check that the IP address of the meter is correct.

•

Check that the subnet mask and IP address of the PC comply.

•

Make sure that communication cables are connected.

•

Try to ping the meter. Type “ping” + applicable IP address in a DOS window.

•

If reply:

Check Host file.

It is also possible to use the IP address directly instead of the host name to avoid problems with Windows host file.

•

If not reply:

Check communication cables.

Check that the link led on the PC and on the UDSP board is lit.

•

Note: Changing a PC’s IP address some times requires resetting the PC for the changes to take effect.

•

Flow rate - Total calculated volume flow rate.

•

Flow velocity - Showing the weighed average flow velocity for all paths.

Used to calculate actual volume flow rate.

•

VOS (velocity of sound) - The average Velocity of Sound for all paths.

•

Log count indicating how many measurement cycles have passed since the meter was started.

•

Used temperature and pressure –What is in calculation. Geomity correction and transducer calibration selection.

•

Total accumulated volumes – Forward and reverse.

•

Profile flatness – 100% means a totally flat profile. Outer / Inner * 100.

•

Profile Symetry – 0% is perferct symmetry. Positive number means more flow in the top.

•

Swirl and cross flow

4.2.3. Current Path Values

•

Flow velocity - The variation between the paths should be according to expected flow profile. For a well developed flow profile the flow velocity for center paths should be higher than the flow velocity for outer paths.

•

VOS - The variation between the paths should not exceed 1 m/s (~3 ft/s)

•

Turbulence – The amount of scatter on the path velocities (Standard deviation in %)

•

S/N Raw and S/N Used. The amount of noise on the sampled signal and after signal processing.

•

Signals - Number of signals (in percent) used to calculate the path velocity is usually above 90%, may be lower at high velocity. If the value is below

30%, special attention is needed to check that flow velocities and velocity of sound measurements for each path are correct.

•

Gain - This shows the receiver gain for each transducer. The gain is a number in the range 0 – 2600. The gain is adjusted automatically to achieve required signal amplitude. The value is dependent on meter size, operational pressure and flow velocity. Typically in the range 300 – 1500.

Individual variations due to different path lengths and turbulence levels are expected.

•

Shows the axial flow components in each layer, resulting in the actual flow profile. Green bars indicate forward flow, red bars reverse flow. The numbers represent the percentage above or below the average total flow velocity.

When the alarm or alarm log system indicates that something might be wrong with the meter, the Winscreen program can be used to help identifying the problem.

The Winscreen program contains various selections of diagnostics and service tools. Normally the alarm will give a hint about what kind of problem the meter is experiencing. In this chapter, a full diagnostic of the meter will be performed from signal to generated output to cover the range of diagnostic tools available in Winscreen.

As a result of the diagnostics you should have a few files saved on your computer. These files describe the state of the meter:

1.

Database file (.db)

2.

Analyzer file (.sig)

3.

Trend log file (.txt)

Check list:

1.

In the view where all signals are visible at the same time, check that all paths look approximately the same. Check that there is not extensive level of noise on any channels.

•

If a channel has weak or no signal (compared with the noise), check the transducer cables and connections of that specific transducer pair. Other possibilities are defect transducer or input channel at the

UAFE board.

2.

If a signal looks suspicious select the signal by double-clicking. Then zoom into the signal by using the toolbar button “Zoom X”.

•

Look for false signals in front of the real signal. False signals can travel through the pipe instead of the medium if there is direct contact between the transducer tip and the pipe. Check for heavy deposits on the transducer or grease from the o-rings on the transducer tip.

•

Look for heavy ringing after the signal. This can be caused by a faulty transducer.

•

Look for distortion of the signal. Clip out a window of the signal by selecting the “Window” button. Then press the “FFT” button. The presented signal should have a top around the signal frequency (150 kHz for gas and 1000 kHz for liquid.) If strong frequency components are found at 3 times the signal frequency, this indicates signal saturation (3 rd

harmonic content). Possible causes are too high TX gain (Object 423 in the database) or defect input channel on the UAFE board.

5.2. Check signal acquisitions

Open the database of the meter (described in chapter 4.4 or 4.7).

Check the following objects.

•

38-49 Gain. The level should be approximately the same on all channels. High gain indicates problem with the transducer or deposits in the transducer port.

•

80-85 S/N ratio raw signals. S/N level on the raw signal is normally between 20 and 40 dB. Large meters and/or Low pressure will give lower S/N levels.

5.3. Check signal processing



•

Object 0.Check that the log count is counting at a regular pace.

•

26-37 Signal %. This number will indicate how good the signals were identified.

•

86-91 S/N ratios used signals. S/N level on the used signal is normally between 30 and 60 dB. Large meters and/or Low pressure will give lower S/N levels. If “S/N ratio used signals” are below 16 dB the signal are below the minimum quality limit and the measurements might be erroneous.

•

50-61 Transit times. Look for “crazy” values.

•

20-25 Measured VOS. All paths should read approximately the same

VOS.

•

3 Velocity of sound (average). Use AGA 10 (only for gas) or equivalent to verify the velocity of sound. AGA 10 is included in Winscreen. From the main menu select: Tools – AGA10…

•

112 Pulse out total count should count when the meter is generating a frequency. If not, there is a problem with the communication between the DSP and the pulse micro controller (AVR).

•

120-123 Check analog input values.

•

130-135 Check Modbus inputs

6.1. SWITCHING OPERATING MODE

Warning!!! During normal operation it is not necessary to enter Config mode. All operations that are described in this document can be done in

Run Mode. Entering config mode will stop the measurements.

When the meter is in operation mode (Run Mode), the Config mode button is lit. In the lower right corner there is a small window that shows in which mode the meter is operating. This is shown in the pictures below. Run Mode means that the meter is measuring, and Config Mode means that the meter is stopped.

When the meter is in Config Mode, the Run Mode button is valid. Click the

Run Mode button to start measurements.

When the meter is in Run Mode, the Config Mode button is valid. Click the

Config Mode button to stop the measurements.

If the Config Mode button is clicked, a warning will be shown before the meter stops measuring.

6.2. SIMULATION

Winscreen has the ability to make the ultrasonic meter simulate a given flow velocity. If a selected flow velocity and velocity of sound is entered, the

Winscreen program will calculate the travel times and transmit this to the ultrasonic meter. The meter will calculate a volume flow based on these travel times. The calculated values with various units will be presented on the available outputs and communication interfaces. This is especially suited for testing of communication interfaces between the meter and a Flow Computer.

To active the Simulator, set Manual Values to ON under the Modes tab in the

Database Configuration screen.

Warning!!! The Meter will not measure the actual flow when this function is used.

•

Select

Tools

in the main menu in the program.

•

Select

Simulation

.

•

Select

Simulate transit times

.

The following picture will appear.

Page 40 of 96

•

Type in the flow and VOS to be simulated. You can also select various flow profiles to be simulated. (Typical VOS for a gas meter is around

400m/s, while for an Ultra

6

it is around 1400m/s).

•

Clicking the Random Flow Simulator box will allow the Simulator to change values by itself

•

Then click the Download button.

The ultrasonic meter will now calculate travel times based on the input recently typed in, and it will use the already existing parameters in the database to give the correct flow. Note that transducer delays were not taken into account when the Winscreen program calculated the travel times, therefore there will be a slight deviation between the inserted flow velocity and VOS, and the calculated flow velocity and VOS returned by the ultrasonic meter.

•

To return from Run Mode to Simulation Mode, Set Manual Values to OFF under the Modes tab of the Database Configuration Screen

6.8. Modem Communication

Winscreen is designed to communicate to a remote meter via a serial modem over telephone lines. Any commercially available serial modem is compatible, as long as it supports the standard and extended Hayes AT command set.

To configure the modem on the meter side, connect it to the serial port of a PC and communicate to it with HyperTerminal. Send the following AT commands to properly configure the modem:

AT &N6 &W

AT &U6 &W

(Sets the maximum line speed to 9600 baud)

(Sets the minimum line speed to 9600 baud)

AT &B0 &W

AT S0=1 &W

(Sets the port speed to the line speed)

(Sets auto-answer pick up to 1 ring)

Additionally, the modem must be set to DTE Override. Some modems accomplish this via dip switches, and others by AT command. If the modem uses AT commands for this function the AT command is:

AT &D0 &W

Once the modem is properly configured, it is connected to the meter via RS-

232 serial cable. The wiring is reverse of the normal 232 connection, such that

TX connects to Pin 3 and Rx to Pin 1 of COM1 on the meter serial connector.

The modem is also connected to an analog phone line.

To remotely dial into a meter, go to Connection, Properties, and type in the remote phone number and click OK.
