Our technologies and expertise result in first-of-a-kind fittings
Since its inception in the early 1930s when Paul Daniel invented Daniel Senior® Orifice Fitting, whose basic design still reigns at gas pipelines today, Daniel Measurement and Control continues to be a global and powerful force of innovation in the oil and gas industry, particularly when meeting the requirements of large or special applications. Daniel is recognized as the only company in the world able to manufacture 2,500# ANSI class dual-chamber fittings, and one of only two companies able to serve customers with applications requiring fittings size 48 inches, the world’s largest.
With an installed base of well over 1 million orifice fittings worldwide, more natural gas is measured with Daniel orifice meters than any other type of device. From duplex stainless steel fittings to carbon steel and severe service trims (Monel, Hastellloy-C and Alloy-20), Daniel delivers fittings to meet the stringent requirements of corrosive environments or specific temperature and pressure needs. So whatever your next challenge is, Daniel's global custody transfer expertise will help unlock your growth opportunities.
Shale gas producers choose Daniel dual-chamber orifice fittings
 The number of drilling rigs has dropped significantly in the
United States
to 50% of what it was a year ago, the lowest level in nearly 6-1/2 years. More and more attention is being focused on unconventional resource plays—e.g. shale gas. Advances in completion technology and horizontal drilling techniques are making it easier and more profitable for operators to exploit shale formations and direct significant additional capital to these pursuits.
With the increase in shale gas drilling, natural gas producers have relied on Daniel dual-chamber orifice fittings to accommodate the pressure and volume variations in these unconventional wells and provide consistent measurement accuracy. This video explains why Daniel Senior Orifice Fitting has been the meter of choice in these applications.
Daniel's new patented orifice plate holder delivers measurement accuracy
 Orifice plate alignment is one of the most significant factors in reducing measurement uncertainty. Daniel’s patented orifice plate carrier alignment method is compliant with the existing AGA/API 14.3 standards including eccentricity tolerances. It is also important to note that there is a provision in AGA which allows the eccentricity tolerance to be increased by 0.020" on fittings size 2"-8", making up to 0.5% added measurement uncertainty acceptable. With the tight eccentricity of Daniel orifice plate carrier, this added measurement uncertainty is eliminated.
Considering the desired uncertainty control limits for custody orifice measurement is +/- 0.5%, empirical data has shown that orifice applications involving plate centering outside AGA eccentricity tolerances tend to give an under-reading of the actual flow rate. This video demonstrates how Daniel's concentrically aligned orifice plate carrier can reduce your measurement uncertainty.
