Product Details
ORIFICE PLATE
Orifice Plate is the heart of the Orifice Meter. It restricts the flow and develops the Differential Pressure which is proportional to the square of the flow rate. The flow measuring accuracy entirely depends upon the quality of Orifice plate, its installation and maintains. When measuring wet gas or saturated steam a weep hole is drilled in a concentrically bored orifice plate. This is a small hole drilled on the orifice plate such that its location is exactly on ID of the main pipe.
The Orifice plates are manufactured as per ISA / AGA/ API / ANSI standards and in various materials such as SS304 /SS316 / SS316L /Hestoly C / Monel / PTFE coated.
RESTRICTION ORIFICE PLATE
A Restriction Orifice Plate is similar to an orifice plate but is much thicker. It is used to drop upstream pressure of a system. While passing the fluid through thick plate energy is lost in friction and heat resulting considerable pressure drop.
Normally single Orifice Plate having larger Thickness is used. However when the Flow velocities crosses the limit of critical flow and are subjected to sonic velocities to avoid noise vibration and cavitations in the liquid the Restriction Orifice Plates are designed in multistage form.
For Viscous fluids and low Reynolds number the upstream side of the Restriction Orifice plate is beveled.
The discharge coefficient of the restriction orifice plate is, also as per the orifice plate, approximately 0.6 according to ISO 5167. The bore is designed as per ISO 5167 and thickness as per R.W Miller/Ward-Smith.
When the noise through single hole is beyond the acceptable limit sometimes Multi Hole plates are used as restriction orifice plates .The process condition defines the no of holes. Multistage with multi holes restriction is also a possible combination.
