The Mark III meter includes a feature for streaming transducer waveforms that can be viewed 
using the Daniel MeterLink 

 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: 

•

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

•

 - 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.

•

 - 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 

 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.

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

        

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 

 

screen. When the screen is first opened, the 

 table shows the version 

and date for each of the currently installed components.

To download a program file to the meter, click 

 to display an 

 dialog. 

Select the desired file and click 

. The filename is displayed in the 

 edit box under 

. The version and date of the components to download will be displayed in the table 

under 

. 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 

 by default. Select or clear any component’s checkbox under 

 to override the default selections.

At least one component must be checked for download before the 

 button is enabled. 

Click the 

 button to initiate the download. The status is displayed in the 

 section of the screen.

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

 for information on the Configuration 

Protection switch.
