LN2 flow sensor

[jemian@arev.uni.aps.anl.gov (Pete Jemian)]

Hey: 

Concerning the liquid nitrogen pump from Oxford, has anyone
started to read the outputs from the various components in the
instrument rack?

Specifically, the (optional) liquid nitrogen flow sensor
from MicroMotion has an output that can be configured to be 
proportional to the flow rate.  It also has an optocoupler
output that can be switched based on the flow rate.

Seems like I could use that optocoupler to provide an input to
an equipment protection system.  Problem is that to configure
the device (an ELITE Model RFT9739 transmitter), I need to
do it with software using one of three choices:
    1   HART communicator
    2   Modbus Protocol
    3   ProLink Software

Has anybody got any of these?
