Technical GuideDifferential Pressure Flow Meters
Proving its worth every day The Daniel Senior Orifice Fitting is a dual-chamber device that reigns as the most widely used means of measurement for natural gas. With an installed base of well over one million orifice fittings worldwide, more natural gas is measured with the Daniel Senior Orifice Fitting than any other type of device.
The Senior Orifice Fitting (Figure 1) saves users time and money by providing a fast, safe and extremely simple method of changing orifice plates under pressure without flow interruption, preventing unscheduled shutdowns. In addition, its dual-chamber design eliminates the need for costly piping bypasses or additional valves and fittings required with conventional orifice flange installations.
The Senior Orifice Fitting meets all requirements and recommendations for accurate flow measurement of gas and liquid, including AGA 3 / API 14.3 requirements, without compromise.
From duplex stainless steel fittings to carbon steel and severe service trims (i.e. Monel®, Hastelloy®-C and Alloy-20), Daniel delivers fittings to meet the stringent requirements of corrosive environments or specific temperature and pressure needs.
The Senior Orifice Fitting requires no beta ratio range restrictions and no added uncertainty to published values. It is available in 2" through 48" line sizes, and up to 2500# ANSI or 10,000 WOG in 3" to 6" only.

Not intended for production applications.
In Daniel Senior Orifice Fittings, the slide valve seat (Part No. 18) is part of the upper chamber. The slide valve strip (Part No.3) moves underneath this seat, thereby utilizing line pressure to affect a positive seal. The slide valve strip is maintained in the “floating” position by minimum spring pressure.
Before the slide valve (Figure 4) is opened, sealant (lubricant)is injected using the grease gun (Part No. 23). Pressure is then

Alignment of Meter Tube Flange to Orifice Fitting Flange
On 300# ANSI fittings or smaller, three dowel pin flange-alignment holes are drilled in the flanges.
On Daniel 400# ANSI fittings or larger, flanges are manufactured with close-tolerance, square-shouldered, large male flange-facing on fitting, and large female flange-facing on meter tube to assure proper internal alignment.
Flange gaskets are precision-cut so they will not, under compression, extend into the internal bore of the fitting. Refer to Figure 3.
The Importance of Slide Valve(1) Lubrication
equalized throughout the entire fitting by operation of the equalizer valve (Part No. 1). Equalized pressure on both sides of the slide valve strip allows the slide valve to move freely without wear. The metal-to-metal hard seat seal (with injected sealant / lubricant) provides an optimal and reliable seal in the production environment where sand and particulate matter are common.

Technical GuideDifferential Pressure Flow Meters
Plate AlignmentThe plate carriers in all 2" to 8" Senior Orifice Fittings are centered using a fixed three-point positioning system. This assures orifice plate concentricity in accordance with current API 14.3 (AGA Report #3) tolerances while the fitting is positioned in the vertical and horizontal planes.
The Senior Orifice Fitting is composed of two independent compartments separated by a hardened stainless steel slide valve.
The side sectional view, Figure 5, demonstrates the slide valve in the closed position and the orifice plate concentrically aligned with the flow. The slide valve cannot be closed unless the orifice plate is concentric to the bore of the fitting or in the upper chamber during plate removal.
Figure 6 demonstrates the Daniel top chamber in the opened position with the plate carrier in place for change or inspection of the orifice plate. Only a few turns of the operating wrench are required to loosen screws to remove or replace clamping and sealing bars. Set screws always remain in the clamping bar. This feature adds greatly to speed and ease of operation.
The plate carrier is raised and lowered by a double rack and pinion mechanism with power applied through an operating
wrench. This method provides the safest means of operation with the least amount of effort and assures positive control of the plate carrier at all times(1).
All parts, including the essential slide valve assembly, may be replaced or repaired without removing the fitting from the line.
Orifice Plate Sealing UnitsDesigned by Daniel, the plate sealing units provide a secure seal between orifice plate and body seats and can be used for a variety of services.
Plate Carrier
The plate carrier protects the orifice plate at all times while inserting or removing the plate from the fitting and can be easily inserted while the fitting is rolled in the horizontal position.
Indicator Plate
The indicator plate clearly shows the position of the slide valve within the fitting.
PTFE Shaft Packing and Centering Rings
The PTFE shaft packing and centering rings are standard equipment on all Daniel Senior Orifice Fittings in all sizes and ratings.
Compact Design
The compact design of the Senior Orifice Fitting requires minimum operating space.
Fittings
Daniel Senior Orifice Fittings up to and including 12" line sizes can operate in a vertical down flow condition or positioned in horizontal flow for side opening.
All fittings are designed and manufactured to meet API / AGA recommendations, and are in strict accordance with ASTM specifications. For other code requirements and special applications, including NORSOK, ISO, PED, CO2, H2S, and low temperature, please consult factory.

Orifice Plate Sealing UnitsOrifice plates manufactured by Daniel are quality-controlled from the selection of raw materials to the packaging of finished products. The orifice plate sealing unit provides a seal between the orifice plate and body seats and it is available for a variety of services.
Dual Seal (DSC, DS and DVS) The Dual Seal (DSC) is the simplest and most practical orifice plate sealing device for normal flowing streams. It is precision molded from 70-80 shore nitrile synthetic rubber(1) and provides four rubber-to-metal sealing surfaces 360° around the plate. The units securely seal against both outer faces of the plate and against both seats of the orifice fitting to prevent leakage.
In 16" sizes and up, DS rings are not available. The Dual Vulcanized Seal (DVS) that bonds 80-90 shore rubber directly to the outer edge of the orifice plate at the factory is recommended for 12" fittings and larger. If damaged, the DVS and plate may be returned to the factory to be rebonded. Both DSC and DVS are used in Daniel fittings up to 600# ANSI, for temperatures from -28°C to +135°C (-20°F to +275°F).
Snap Seal Ring (SSRC and SSR)The Snap Seal Ring (SSR) unit is a removable orifice plate holder designed for use where elastomer seal swelling is a problem. Certain media, such as ethylene or carbon dioxide, may cause seal swelling when other types of seal units are removed from high-pressure service.
The Snap Seal Ring unit consists of two symmetrical metal rings, each one having an O-ring on both sides for a secure seal on the plate side and the fitting side of the ring. The orifice plate is centered and secured between these rings. The assembled unit provides a full 360° rubber-to-metal seal around both sides even in the absence of pressure differential.
No special tools are required for assembly or disassembly.When ordering, please specify nominal line size, schedule, plate thickness, and flowing media or material choice.

PTFE Seal (TSC and TS)The PTFE Seal (TSC) is a superior orifice plate seal unit for difficult, corrosive flows and for higher temperatures than the Dual Seal (DSC) unit can handle. The TSC has proven effective in flows such as dilute sulphuric acid, fuming nitric acid, hydrazine, liquid oxygen and other unusual flows, from -53°C to +260°C (-65°F to +500°F)(1).
The two-piece unit consists of an inlet ring which fits around the outer diameter of the plate, and a downstream ring fitted with metal clips for assembling the orifice plate sealing unit. A unique, annular groove(2) on the ring provides compression to effectively seal off the plate.
The TSC unit can be assembled or taken apart by hand and is interchangeable in 2" to 10" sizes with Daniel Dual (DSC) and Metal (MSC) Seal units. The TSC is recommended with Daniel 900# to 2500# ANSI fittings or lower pressure where rubber seals may not be satisfactory.
Metal Seal (MSC and MS)(3)
The Metal Seal (MSC) is a stainless or zinc-plated carbon steel clip-ring assembly recommended for high pressures and for temperatures up to +648°C (+1200°F)(4). The assembly consists of an upstream and a downstream ring. The upstream ring has a recessed groove into which a thin leaf-spring is inserted. A seal is created by clamping the plate between the rings, thereby providing the necessary compression to seat the plate against the downstream ring.
Metal Seal units of zinc-plated carbon steel are recommended for services to +315°C (+600°F)(4), standard 316 stainless steel units to +537°C (+1000°F)(4), and 316 stainless steel units with an Inconel® spring to +648°C (+1200°F)(4).
The Metal Seal unit can be assembled or taken apart by hand and is interchangeable in 2" to 12" sizes with Dual Seal (DSC) and PTFE Seal (TSC) units.

January 2015Senior Orifice Fitting
The new Daniel plate carrier reduces measurement uncertainty using a three-point positioning system. This assures concentricity within the fitting in accordance with API 14.3 (AGA Report #3) and ISO-5167 standards. Metal-to-metal contact of the plate outer diameter with the inner diameter of the plate carrier, coupled with precision contact points of the plate carrier to the fitting affords users consistent compliance with AGA eccentricity requirements in a vertical or horizontal plane.
Design Features1. Precision ground corner tabs keep the orifice
plate carrier in the proper position and allow the fitting to be mounted in the nine, twelve or three o’clock position (See Figure 7)
2. Notched seal ring design provides metal-to-metal contact for reliable alignment and centering of the orifice plate
3. The fitting’s pin and the spring loaded button located at the top of the orifice plate carrier ensure tight positioning of the plate carrier when the slide valve is closed and the Senior Orifice Fitting is in the vertical or horizontal metering position
4. Wide flow ports reduce differential pressure load across the plate surface
5. A 360° seal ring support shelf secures the plate in place
Orifice Plate Carrier
The new plate carrier is compatible with Daniel Senior Orifice Fittings manufactured after 1991. To upgrade the plate carrier of your Senior Orifice Fitting, please contact your local Daniel representative.

Daniel Lubricant
Lubricant Stick
Daniel lubricant is specifically designed for lubricating the slide valve(1) of Senior Orifice Fittings, ensuring maximum operating performance. Because it is a chemical compound rather than a petroleum based product, this lubricant has significant advantages:
• Effective over a wide range of demanding temperatures (-20°F to +160°F) and pressures (0 to 1,400 psig)
• Contains no fillers or inert materials, eliminating hardening or oxidizing
• Reduces friction and wear, extending equipment life in severe conditions
• Insoluble in water and extremely resistant to hydrocarbons within its temperature range
• Different types of lubricants are available to meet the various demanding needs of gas applications
Daniel lubricant is available in B-sized sticks (3/8" diameter, 1.5" long) in 24-stick boxes. The cylindrical shape of the grease stick fits neatly into the fitting’s grease gun (Figure 8).
NoteHard seat (using sealant / grease sticks) is standard on all Daniel Senior Orifice Fittings, providing an optimal seal in the production environment where fractionation sand and other particulate matter are common.
Soft seat (O-ring seal using no grease) is available in 2" to 12" and up to 600# ANSI for use with gas products such as ethylene.
