The “J-Flow” Single Chamber orifice fitting provides highly accurate orifice flow measurement and orifice plates that are easily removed from a depressurized meter tube. Our intuitive design is intended to make inspection or removal of orifice plates extremely quick and simple.

The J-Flow requires absolutely zero maintenance once installed, making it a cost-effective solution for long term use. Our robust design requires no greasing or tightening and has no breakable parts. The J-Flow is a smoother, better performing single-chamber solution due to the quality of workmanship put into the product.

The Single Chamber J-Flow fitting is available in a complete range of sizes and pressure ratings to fit your gas measurement equipment. Single Chamber Fitting sizes 8″ and larger use a shaft-driven plate carrier for easier removal of larger plates. The lower chamber can be used if the convertible top is removed, and a Dual Chamber Top is ordered to convert this style to a Dual Chamber-design orifice fitting.
