(OP)
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?

RE: wastewater flowmeter

RE: wastewater flowmeter

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.

RE: wastewater flowmeter

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.

RE: wastewater flowmeter

(OP)
the pipe will be flowing full at the time...

Any experience with Rosemount Flowmeter?

RE: wastewater 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.
