Tricky fluid flow measurement of multi-phase fluids

[JimERM]

I'm spec'ing flow measement device for a groundwater and LNAPL (petroluem)recovery system. The system includes the use of double-diaphragm pumps as the means to recover the fluids from wells. Groundwater will be drawn down to the suction inlets until slurping action draws air/oil/water. I suspect that it will be mostly air. Fluids from wells combine and will be discharged directly to a collection sump/vault where other discharges converge. Other than counting pump pulses via air pulse counters or cycle counters, can anyone suggest a means to accurately measure the liquid flow from this setup?

Best Regards

See this 2-phase meter from Foxboro,

Thanks for your input...I'm looking into this meter right now...its about $7000

I think that'll be cheaper than separating the phases and metering each phase separately.
