Fiscal metering system
thread481-243523

Hi..This is in continuation to the referred thread on Metering system.

For metering system, I have few questions :
1.the importance of Pressure Balancing line at the Inlet at of each metering train and recommended sequence of operating this balancing line.
2.Process performance Guarantee parameters normally given for the Metering Package.
3. Metering process line size to Inlet / Outlet header/

What are you measuring? what is the line Size? What is your desired flow rates? You use the word fiscal, so I assume custody transfer is applicable?

What "pressure balancing line" - you need to post a diagram so we know what you're talking about

normally you want to specific "uncertainty" for your chosen parameter ( volume, energy, mass), i.e. what is it that you are measuring and what instruments are you using. Repeatability is also a good number to specify.

Metering lines are often 2-3 pipe sizes smaller as the y like higher velocities, but each type of meter is different and depends on flow, pressure etc.

give us something to work with here and we can help you, but not searching around in the dark.

There are lots and lots of issues with "fiscal" or custody transfer systems which mean you really need someone or company that knows what it is doing. A 0.1% error on say $100M of product and that's $100,000.
