multi-hole flow orfice meters
multi-hole flow orfice meters
(OP)
Has anyone tried A+ flowtek's balanced flow meters (http://www.aplusflowtek.com)? I am trying to find people with first hand operational experience to support or dispute their claims of flow metering accuracy to +/- 0.5%. They are a NASA spin-off company. I also know that Texas A&M did some research on multi-holed orifices in the 1990's. Please let me know if you have used (particularly A+flowtek's balanced flowmeters)them and what your experiences have been.

The multi-hole orifice plates have cavitation coefficients 3 or 4 times less than the equivalent single orifice plates. They have also a best recovery pressure factor and recovery pipe full flow, so they need less pipe straight run downstream the plate.
I have designed and installed many restriction multi-hole restriction orifice plates in different thermal and nuclear power plants.
For these reasons I assume that as meter orifices the multi-hole plates are better than the traditional single orifices but I don't know which will be the final accuracy.

The perforated orifice plate is a circular disc having multiple circular bores with sharp 90 degree corners at the inlet face. Perforated orifice plates are used when the pressure
drop across an orifice plate with a single bore may cause cavitation to occur.
Thank you for your all reply and comment
