6.7Viewing transducer waveforms

The Mark III meter includes a feature for streaming transducer waveforms that can be viewed using the Daniel MeterLink Tools - Waveform Viewer screen. The speed at which the waveforms update is dependent upon the type of connection between the PC and the meter. With the optional Ethernet connection and Daniel MeterLink, several updates per second are possible. With a serial connection, updates may occur only every 15 to 30 seconds.

Up to three types of waveform signals can be displayed per chord:

•Raw - the sampled waveform received by the transducer (with gain applied)

•Stacked - the result of applying stacking to the raw signal(s). Note that when stacking is not used (StackSize is set to 1), the stacked signal is the same as the raw signal.

•Filtered - the result of applying the bandpass filter on the stacked signal. This waveform is only available when the filter is enabled (via the Filter data point).

For diagnostic purposes, the transducer waveform signals can be stored to a file using the Diagnostic Collection - Stream to file check box. This utilizes the Mark III meter’s patented “snapshot-and-playback” feature to accurately record the flow conditions that can then be later reproduced for detailed analysis.

6.8Upgrading the meter program

The Mark III meter program is stored in flash memory so that it can be easily upgraded.

The Mark III program can only be upgraded if the configuration is not protected via the Configuration Protection switch. Refer to Section 3.5.8 for information on the Configuration Protection switch.

The Mark III program consists of three components: the operating system kernel, the file system, and the firmware. The program file to download to the meter is a “.zip” file that contains all three components. Do not unzip this file with PKZIP or WinZIP.

To upgrade the Mark III meter program, use the Daniel MeterLink Tools - Program Download screen. When the screen is first opened, the Currently Installed Versions table shows the version and date for each of the currently installed components.

To download a program file to the meter, click Open to display an Open Download File dialog. Select the desired file and click Open. The filename is displayed in the File edit box under Upgrade. The version and date of the components to download will be displayed in the table under Upgrade. Each component is identified as either older, newer, or the same as what is currently installed in the meter. Only components that are newer than what is currently installed are checked for Download by default. Select or clear any component’s checkbox under Download to override the default selections.

At least one component must be checked for download before the Download button is enabled. Click the Download button to initiate the download. The status is displayed in the Upgrade Progress section of the screen.
