The  flowmeter  is  controlled  from  a  PC  running  "Viewer  BUF-311" 

program. The program is available free of charge. 

The interface includes several tabs classified by their function. Con-

tents of the tabs is determined by the flowmeter's operation mode. After 
the flowmeter is powered up, the operation mode is detected automati-
cally.  

4.1. Configuring before work 

4.1.1. Installing the dedicated software and system requirements 

BUF-311 program was designed to control the flowmeter and han-

dle the measurement data. Viewer BUF-311 works under Windows 98 
(Me, 2000, XP, Vista, 7) operating system. 

To  install  Viewer  BUF-311  program,  create  a  directory  with  the 

same  name  and  copy  BUF-311.vpr  file  to  this  directory.  The  program 
does not require another installation procedure. 

4.1.2. Getting started 

Connect  the  serial  port  of  a  PC  and  RS-port  of  the  flowmeter 

RS232/485 or USB-RS232/485 adapter by a cable. Activate SERVICE 
mode (place a jumper on J2 terminal). The list of parameters to be con-
figured on-site in SERVICE mode is given in Appendix C. Run the BUF-
311.vpr file. Wait for the main window shown in Fig. 5 to open.

 

Fig. 5. Main window 

Click on the leftmost icon in the command line of the main window. 

By doing so, the connection with the flowmeter is established. The win-
dow will take the form pictured below (Fig. 6).
