The flow of He II is generated with a bellows pump through a 1 m long, 73 mm inner diameter experimental channel containing the orifice plates: the ratios of orifice diameter to tube diameter are 10 % and 20 %.

At the large mass flow for the experiment with the orifice size 10%, the pressure drops are unstable which is probably caused by cavitation in the downstream of the orifice.

A temperature increases through the orifice plate caused by the pressure drop has been observed.

It has telemetry features and improved accuracy under fluctuating flow conditions based on functional differential pressure root mean squared volume calculation principles.

The measured discharge coefficient for the orifice size 10% looks to be larger than the corresponding value for classical fluids although it agrees reasonably well with previous results on a similar geometry in classical fluids.According to Leigh [1], metering costs are often included in the tariff that field pays or may be allocated on a shared basis amongst different fields as part of an operating services agreement.It was also noted that this approach affects the way future value can be generated.Accurate measurement of the total quantity of gas that has passed through a given section of pipe over a period of time is of utmost importance to the gas industry [2,3]. Currently, it has become necessary to weigh needs in different areas against each other.The type of differential metering system often used in Nigeria gas fields is the orifice meter. This is because there has been a number of changes in the area of field economy and field development.

Accurate metering of gas flow rates is an important issue in offshore production.
