Flare System Metering
Flare System Metering
(OP)
Has anyone used flare system meters that really work? I've tried a couple of different kinds, but they just don't seem to be reliable. Ultrasonic, optical, - I need something with a massive turndown, amazing accuracy and it has to work in dirty sour service, big ambient swings, and usually about 20' off the ground.

Have you looked at that? Just for information
You sure don't ask much.

Face it, there's never going to be a good way to do this. It's going to be a series of compromises, whatever you choose.

Perhaps tell your operators to stop blowing their noses into the flare header?

Flare headers also have the possibility that the makeup of the stream can change dramatically from event to event. That seems to make an impossible problem even more difficult.

Pitot tube "flow measurement" is appropriate inside of labs with absolutely controlled parameters. A couple of percent change in density (for example) results in tens of percent change in reported flow. Nothing about using them in flare metering makes sense.

in really rough services, a remote IR camera to monitor the plume or the pressure of the line going to the flare is all that can be used, the flows are estimated from the material and energy balances
