A wide range of adaptors are available that allow 
the Flowmaster 250 to work with your pipework 
and  ttings.  The  standard  tting  supplied  is  to  the 
internationally recognised 2.5” BSP male thread. Onto 
this can be mounted BS Inst. M/F, NH or NST M/F, Storz, 
Nor Kuppling, etc.
The  ow  monitoring  system  provides  a  data  logging 
function on a PC or laptop of the ow rates measured 
by the Flowmaster. The ow monitoring system consists 
of an RS485 to RS232 converter that interfaces the 
ow meter  to  the PC  or laptop, cables  and software 
to capture and display ow data. Screenshots from PC 
software for use with the ow monitoring system are 
shown in Figure 6.4.
