Square Edge Co-centric Orifice Plate: These are most commonly used for flow measurement. This has special feature simple structure, high accuracy and easy installation. These Orifice Plates are recommended where Reynolds number range from 10000 to 10^7.

.

Eccentric: These are used for liquid containing solid particles which are like to sediment or for vapors likely to deposit water condensate, this orifice plates are used with its eccentric bore at the bottom side so that sedimentation of such inclusions are avoided. For Gases and Vapors it may be installed with the eccentric bore at the top side to avoid stay of gas or vapor in its vicinity

.

Segmental: The bore of this type of orifice plates is a semi-circle. It used where solids are entertained in liquid or gas streams

.

Quadrant Edge: The inlet edge of the bore of this orifice plate is rounded to a quarter circle. This orifice plate is principally used for measuring flow rates of low Reynolds number (Between 2000 to 10000)

.

Restriction Orifice Plate: These Orifice Plates are used for reducing fluid pressure. These orifice plates are slightly different from standard orifice plates.

.

Integral Orifice Assembly : This type of assembly is used where the Differential Pressure Transmitter has to be mounted directly on the Orifice Assembly. This eliminates the impulse tubing from Orifice Assembly to DP Transmitter. This type of assembly is used for line size below 2” (50 NB). The transmitter in mounted on the orifice assembly with the help of 3-Way Manifold. The assembly consists of orifice plate with two integral blocks having corner taps. It also consists of a meter run pipe having length of 750mm on the upstream side and 250mm on downstream side.
