Orifice Flow Meters and Vibrations

vibrating equipment?

Do you mean that the pipe is vibrating? My answer is:

Even without the orifice flowmeter (or any flowmeter for that matter), the pipe shouldn't be vibrating. You will not just damage your flowmeter but your pipe, your flanges, your valves, just about everything.

So, to answer your question...no, you shouldn't use a flowmeter in vibrating equipment.

Due to vibration there is possibility of turbulent in pipe. Is there any problem regarding turbulent flow in pipe?.

Turbulence is taboo when using flowmeters. You want the flow to be as smooth as possible. Any turbulence will show up as noise in the flow signal.

Please tell me, whether their are other issues other than the damage of equipment.

Please tell me what are the other flow meters I can use in vibrating equipment?

It is unclear to me what part is vibrating and you never mentioned it. Is it the pipes? Is it the pump? We can give a better answer if you give more information.

As I said, any vibration is usually detrimental to the system. If you'd ask me, I'd eliminate the vibration since any flow meter I suggest will be affected in some way.

Vibration is a symptom of a bad situation. Don't try to work your way around it. Solve it and you'll be freed of more problems than just a noisy flow signal.

I want to install a flow meter in fuel line of a surface miner which is mobile equipment. This equipment is vibrating. The pipe diameter is 24 mm. Pl help me.

'Been away for awhile.

See here. If you had mentioned this at the start, we might have given better answers and we'd have given them earlier.

Okay, now that's a challenging project. I think that you could use a coriolis flowmeter but that would be a bit expensive. Don't use a magnetic flowmeter since it introduces an electric current through the fluid. Since you're measuring fuel, that could be an explosive situation.

A clamp-on ultrasonic flowmeter is easiest to implement and cheaper than the coriolis. I'd suggest you use a transit-time type, not the doppler type.

If you're not particular with accuracy, a positive displacement flowmeter would probably do for this application.

Make sure you secure the flowmeter so that it doesn't bounce around.

Good luck

Than u for your good suggestion. Can I use oval type flow meter?

As Spock Vulcan said, don't put any flow meter (or for that matter any meter or even any piping at all) exposed to vibration.

Why don't you isolate the vibration from the pipeline? all our machines we make, the lube lines are vibration isolated using either flexible hoses or isolation couplings. The flow meters (mostly flow transmitters for us) will be quite fare away, in the LOS (Lube Oils System) and quite away from the equipment.

However if your LOS is mounted on the equimpent itself, then you need some damping mechanism additionally on the skid to avoid passing on the vibration.

It's time to consider restaining the pipework so that vibration is practically eliminated.

I would be more concerned about how the vibration is affecting your DP Gauges or Transmitter
