flow / velovity measurement
(OP)
We are trying to get away from discrete alarming on Exhaust flow. We have considered a number of options with analog transmitters, but I thought that I would through the this out there to see if anyone had any ideas / reccomendations.
the 2 meters I am presently looking at most are Dwyer:

as well as one from E+E Eleoctronics

We are a heavily regulated facility, and it has been stated that more precice SPs are required, and that exhausts will eventuall be mandated to have totalisers.

You can get custom sizes. You need to determine the system accuracy and do a very good initial calibration that is traceable.
Take the delta p output to a transmitter with 4-20ma or 0-10v output. Various mfgs offer complete solutions with local display. It sounds like you are trying to reuse the existing 2 wire alarm system. If the wiring is your problem, you may want to look into a wireless solution.
