From SmartFlow calculated best measuring capabilities and standard deviation by flow computer displayed values the total uncertainty of flow computer can be calculated squear-root-mean calculation. From my experience I would guess that the recommendation in the standard is based on a set of tests with one particular design of expander. Audible Download Audio Books.
Another option is to go with a different flowmeter. If you have a long straight length of pipe in excess of diameters upstream of your expander it is probably fair to argue that if you comply with the guidance given in 51667-2 standard then your installation, with a less severe expansion, will be OK.

Hello Gents and hopefully lots of ladies I am working on some flow meter installations, specifically orifice plates which have to be compliant with the above standard.

If this is the case your flowmeter will not just see the flow disturbance from the expander, it will see the combined effect of the expander and whatever is upstream of it.

It also provides background information for calculating the flow-rate and is applicable in conjunction with the requirements given in ISO In the standard is a table Table 3 – required straight lengths between orifice plates and fittings without flow conditioners which includes distances for s concentric expander 0. Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.
It is not applicable to the measurement of pulsating flow.
