Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure "Tappings", mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary.
Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip on flanges with extra machining.
The image on the right shows a set Orifice Flanges, where a Orifice Plate is mounted and a jack screw is machined. This jack screw is used to facilitate separating the flanges for inspection or replacement of the Orifice Plate and gaskets.
The range of orifice flanges covers all standard sizes and ranges, and all common flange materials. Flanges are available in Welding Neck, Slip On, and Threaded form, and are typically supplied with two 1/2" NPT tappings in each flange.
ASME B16.36 covers Dimensions and dimensional tolerances from orifice flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections. Coverage is limited to the following flanges:

Turbidity Meter and Suspended Solids Sensors – The Triton® TR86 is a infrared optical sensor designed for analysis of turbidity or suspended solids in water and wastewater. This online turbidity meter is available in two optical configurations, one with side mounted optics, for flow through and immersion service and the other with axially front mounted optics, for immersion service or vertical mounting in a piping system. The Triton® TR86 turbidity sensors are designed to work with the Model T80 Transmitter. The T80 Transmitter allows the turbidity/suspended solids measurement to be combined with any of the other standard measurements, S80 pH, S80 ORP, S80 pIon, S80 Conductivity, S80 Dissolved Oxygen or DO82 Dissolved Oxygen.
The Triton® TR86 Turbidity Meter and Suspended Solids Meter are available in two optical configurations, one with side mounted optics, the Triton® TR86-2 and the other with axially front mounted optics, the Triton® TR86-1. These design options address the fact that reflective surfaces in the emitted lights range will yield artifically high readings. The side mounted optical configuration minimizes interference from surfaces below the sensor while the axially mounted optics avoid interference from surfaces around the sensor. A daylight rejection filter blocks sun light and reduces ambient-light interference. The axial front mounted optics of the Triton® TR86-1 are surrounded with a copper ring that inhibits the growth of algae and other biological films.
