§7.4 Set up PC Software
Windows HyperTerminal software can be used to communicate with the flow meter. You may also make
your own PC software to communicate to the flow meter by using the protocol described in the following
section. Any PC software can be used to communicate with the flow meter if the user follows the
subsequent protocol.
To facilitate the use of and to fully explore the potential of the RH40 flow meter, Spire Metering has
developed proprietary PC software, StufManager
