Orifice Plate
Description
Orifice plates or diaphragms are the most commonly used primary elements for differential pressure flow measurement. They allow measurement over a wide range of flow rates and for a wide range of pipe diameters. There are several types: the sharp-edge orifice plate, the best known, the other concentric plates with conical inlet and quarter circle plate for the measurement of low flows or viscous fluids and the eccentric plate or segmental plate for the measuring dirty or impure fluids. Finally, the multi-hole / conditioning orifice plate allows a measure of quality while providing a minimum footprint. Inserted within a circular pipe, they create an obstacle, increase the speed of the fluid and generate a pressure difference between upstream and downstream of the restriction. This differential pressure measurement is proprotional to the flow rate value.

Plate mounting: plates mounted in serie - optimized plate spacing for each unit from 1D to 5D (D, pipe internal diameter). Number of plates: calculation of the number of stages optimized according to the specifications of the application, each plate making it possible to reduce the maximum pressure while avoiding cavitation and critical flow phenomena. For more details, see our Frequently Asked Questions. Noise: check of the noise level of the complete unit estimated at 1 m. Multi-holes plates reduce the noise level per stage. Solutions of external envelopes can be recommended if the noise remains too high (consult us). Thermodynamics: the thermodynamic properties of the fluid are taken into account for the calculation of each stage: change of state, temperature, composition and density of the mixture, viscosity, compressibility factor. 3D simulation: possibility of a numerical simulation to complete the analytical calculations.

Orifice diameter: dimensioned according to the fluid, to the pressure drop to be achieved and to the flow going through the restriction. Plate thickness: calculated taking into account the pressure drop generated by the plate and the diameter of the pipework to prevent plate deformation. See more details in our Frequently Asked Questions. Noise: control of the estimated noise level at 1 m. In case of high noise level, refer to the multi-hole plate. Cavitation: The cavitation level is checked for each plate. In the presence of cavitation, a multi-stage restriction orifice alternative may be proposed depending on the operating conditions of the restriction. For more information on cavitation, see our Frequently Asked Questions. Critical flow or choked flow: if the fluid reaches its maximum speed when passing the restriction, its flow can not increase. A multistage solution can be proposed depending on the operating conditions of the restriction. For more information on critical flow
