Daniel® SeniorTM Orifice Fitting

 

 

The Daniel® Senior Orifice Fitting reigns as the most widely used device in gas measurement.


Operated by one person, this differential technology meter saves time and money in many ways. It permits plate-changing under flowing conditions, which means no operation shutdown. By maintaining flow during plate changes, the fitting also avoids the burden of bypass piping.


Customers demand this product for other reasons, including its many sizes and pressure ratings. Daniel is the only company with a fitting larger than 42 inches and pressure ranges higher than 2,500# ANSI. With this product and Daniel’s complete product line, the customer meets requirements with a minimal number of orders.


In addition to multiple sizes/pressure ratings, the device is field-repairable. That means no downtime and other costs associated with shipping to a repair site. This fitting also offers special trim and an available soft seat.


The timed-proved product meets API 14.3 and ISO 5167 requirements. It also gives the global customer convenient access to Daniel’s calibration facility and other excellent technical support.


Customers have purchased more than 500,000 Daniel Senior Orifice Fittings in the past 70 years. Despite that impressive history, this fitting remains a product for today and tomorrow.
