Restriction Bore Orifice Plate Definition

Restriction Bore Orifice Plate An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate). Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.

An Restriction Bore Orifice Plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta where the velocity reaches its maximum and the pressure reaches its minimum. Beyond that, the flow expands, the velocity falls and the pressure increases. By measuring the difference in fluid pressure across tappings upstream and downstream of the plate, the flow rate can be obtained from Bernoulli's equation using coefficients established from extensive research.

Restriction Bore Orifice Plates implies two main types of flow limitation exist. One type is the Restriction Orifice Plate, which in construction and calculation follows the orifice plate, i.e. the restriction orifice plate has a thickness of 3- 6 mm depending on the size of the tube. The discharge coefficient of the restriction orifice plate is, as for the orifice plate, approximately 0.6 according to ISO 5167.

For this type of restriction orifice plates the flow quantity through the orifice plate will vary with the pressure before and after the orifice plate.

The restriction orifice plate is mostly applied in non-critical flow limitation. This could for instance be after a control valve in order to divide the required pressure loss into two elements. This is done to reduce the noise in liquids and to avoid cavitation. It is advisable to avoid cavitation in order to protect the process elements before the restriction orifice plate in blow-down systems, and as flow limitator.

The use of the expression "non-critical" must not be compared to the word "critical" in critical flow devices. Non-critical is here to be understood as non-complicated with less requirements for the accuracy.
