wastewater flowmeter

[siblak]

Im looking for a flowmeter for wastewater application. it will be in line and built on the discharge pipe (6 inches diameter) Does anybody have experience or suggestion?

 

[BobPE]

what is your anticipated flow range?

 

[siblak]

around 20 or 25 l/s.

thanks for replying.

A mag flow (electro magnetic flow meter) or a time of flight are the normal solution. ABB, Danfoss or Endress and Hauser are typical suppliers (of many) of this equipment.

BobPE asked about the flowrate; but, another question is "will the pipe be flowing full all the time?"

The mag meter will not work on a partially full pipe.

Another option is an ultrasonic flow meter. With area and velocity readings, it can give a flow for a partially full or full pipe.

the pipe will be flowing full at the time...

Any experience with Rosemount Flowmeter?

If the pipe flows full all the time, mag meter is good.
If it does not flow full, maybe a Parschal flume.
I have not had consistently good success with ultrasonics in permanent installations. Flow is affected by TSS in wastewater.

Rosemount is a brand of instruments, not a type of flow meter. I don't know what kind you are referring to. Rosemount is generally good.
