Flow meter for high vibration pipe 1

[Swng]

I would install the flowmeter on the high vibration type,
So I'm not sure which type of flowmeter would suitable for this application

Swng,
What is causing the vibration Centrifugal pump, Piston type pump or something else?
Vibration is not good for any flowmeter but if we know more we may be able to suggest a solution.

Look at orifice plates.

If the fluid is conductive, you could consider magnetic flowtubes.

And, as usual, you leave huge gaps in our abilitiy to help you by not defining:

What fluid, what temperature, what pressure?
How much vibration, at what frequencies?
What accuracy is required?
What have you tried that doesn't work, and why?

 

[Swng]

The fluid is wase water, and the pipe connect from the centifugal pump, the vibration rate about 10mm/sec. , the existing flowmeter is magnetic flow meter the problem is the electronics board was broken.
Temperature of fluid about 30-40*c and the pressure in the pipe is 3-5 bars.

Please advise.

"...the problem is the electronics board was broken."

Can you move the flow sensor downstream where there's less vibration?

Can the sensor unit be modified so that the electronics board can be moved just off the vibrating pipe? Perhaps supported by a fixed mount a fraction of an inch outside the maximum vibration zone (plus a bit for safety). Some might point out that the wires from the sensor to the circuit might break, to which I reply: There's got to be wires anyway. The advantage of this is that it might be a lot easier to modify a replacement sensor than to re-engineer the whole system.

Another option, less straightforward, might be to figure out how the board is vibrating and damp it out. Maybe it is a simple flex failure and could be stopped with a dab of glue. Or contact the manufacturer and ask their help.

Agree with V1Bll, change the mag meter to a seperate flow tube and amplifier/transmitter. I.e. the only thing on the pipe is the flow tube and electrodes, all of the electronics are mounted off the pipe. Whoever makes your existing mag meter should be able to help you find a replacement model. Some big names are Foxboro, Rosemount, and ABB.

Try an Endress and Hauser ultrasonic flow meter, its quite expensive but will do the job.

If you are really sure that the problem was brought about by the excessive vibration of the piping, why not solve the vibration problem first? Piping clamps, rigid pipe supports and many other fasteners could do the job.
