Help please with Control Flow Valve + Ultrasonic Meter AGA 9

[Cesar Almada]

Hi everyone

I have a question about if I have a Control flow valve and after I have your ultrasonic meter in a process of natural gas.

A transporter of natural gas told us that if we have that configuration it's possible that poor measurement occur.

I don't know if it's right, because i designed my meter package with AGA 9 and i respected the distances between spools.

I attach the drawing of my package of control flow and meter, if you can help me how can i explain that is unnecessary to change my packages between them and how being right now its okay.

Hi everyone

I'm going to update this thread or issue quickly. I understand to everyone who said, that move the valve and the meter it would be quickly and better, yes I agree with you, but we didn't have time to do that because we needed to open the valve for our costumer.

Our provider told us that is acceptable to do this kind of installation, because their meters has high quality transductors that support the noise. So they gave us a letter committing with the good flow measure

So out customer agree with that and we comply with AGA and we finished the project.

Thank you everyone for your answers and help.

Now you get to see if it does.
Let us know how the flow test goes.
If the operating pressure downstream is stable, it should be OK. If not ..you can't control it.
In any case, glad your problem is ... solved.
