transmitter + controller for a dP flow measurement
transmitter + controller for a dP flow measurement
(OP)
Hi,
We would like to replace our dP measurements for a venturi flow measurement. There are 4 measurement venturi's in a reaction zone measuring the air flow to 4 reactors. It is difficult to connect these new systems with our old DCS system.
Would the following be possible?
- a new dP transmitter on each venturi which has an integrated controller to control the air damper. the set point in m³/h is send to the transmittor/controller (wireless or 4-20mA) from our DCS system.
Is there industrial equipment available to do this (Emmerson, Honeywell,...)
Thanks in advance!
best regards,

RE: transmitter + controller for a dP flow measurement
I'm told Foundation Fieldbus (FF) devices have a PID function block. But when you do things with FF, all the pieces have to be FF: field instrument, valve positioner, DCS. FF is a different way of doing business.
You could always do the pre-DCS analog way: local PID controller, analog DP transmitter, analog valve actuator positioner.

i keep you informed about our solution (but it can take a while).
thanks again,
