Flow Computer non based on PC
Flow Computer non based on PC
(OP)
Hello:
I am looking for information about the differences between a flow computer based on PC and a flow computer non based on PC. The answer seems to be clear, but I would like to have more opinions about advantages and disadvantages.
Thanks in advance

RE: Flow Computer non based on PC
A flow computer, like the Fisher FloBoss 504 is a dedicated flow computer. It comes pre-programmed with pretty much everything, and you just need to configure it. It is robust, designed to work in the field and has all the certification.
A PC flow computer is typically located in a building. The instruments need to be wired back to the building. There is probably more costs with the PC solution, unless the infrastructure is already in place.
Can you be a bit more clear, and describe more what type of information you are looking for?

My question is related with a new installation in my work. It is being installed 3 Flow computers but the vendors say that it is needed 3 laptops or desktops computers. Why it is needed? Is not enough the flow computer itself?
RE: Flow Computer non based on PC
The vendor's response makes some sense if this is the context.

I later was much impressed with those wonderful displays with the different digits appearing at different depths within the display.
The first company to introduce micro-processors into flow computers were Solartron; these were their fiscal flow computers for refinery and pipeline applications but soon became used for much more.
The sophistication of the programs was impressive and still is as they become ever more complex.
Flow computers tended to be dedicated single loop systems.
Later they introduced digital coms to communicate with PCs, SCAD systems etc.
They have tended to be rich in dedicated I/O; analogue inputs and outputs, alarm relays, density and viscosity transducer inputs and power supplies, flow meter inputs of various types and so on. Rudimentary data logging and alarm logging came along.
Computers evolved into a supervisory role and data logging role.
Soemwhere in the middle were some pretty neat programs for PCs to run flow programs.
Now we should see further evolutions of flow computers, still single loop or multi-channel (perhaps 4 meter systems say) but with more computer technology such as LCD screens and Windows style environments, user programming capability and expandable I/O etc they are set for far greater flexability.
In other words, we are seeing a rapid blurring of the margins between what is a what and what one should use.

Flow computers like the Daniel FloBoss504 handle a single meter run. The FloBossS600 handles up to 6 meter runs.
I am not sure what you are doing. Are you using "flow computers" similar to the FloBoss504/S600? Are you wiring back to a "control system"?
Please give more specific information. You may be using terms that are clear to you, but seem confusing to me.

I believe I'm clearer now, with your opinions and additional information from the vendor.
The system which is being installed is a Bristol, in fact this is a Flow computer that can do computational calculus. These computers will measure transfer custody of diluent, gas, and oil. And the laptops just are needed as a HMI (Human Man Interface). Just to print reports, see graphics. Etc.
Thanks a lot
RE: Flow Computer non based on PC
A laptop is a common tool to print/HMI/interface.
Why did the vendor say you need 3 laptops/computers? I would think that one is all you need.

Unfortunately, in my old age, it doesn't always register. I guess I still consider Daniels and Bristol different vendors.
There is currently a lot of consolidation in the I&C world.
