Multi-hole orifice plates are variants of orifice plates likes quare edge, eccentric or segmental orifice plates. The main difference consists in the 4 bores radially displaced relative to the plate centre. The model FLC-MP requires only 2 diameters downstream and 2 diameters upstream. Due to this configuration the multi-hole orifice plates ensure a uniform flow of the medium. This enhances the accuracy of flow measurement and minimises disturbances in flow, offering the orifice plates offer high performance even in short upstream and downstream pipes.
A simple and cost-efficient solution
Due to their rectifying effect on flow and easy installation, model FLC-MP multi-hole orifice plates increase cost-effectiveness and flexibility in terms of application areas.
Going beyond international standards
The multi-hole orifice plates are designed and produced in accordance with WIKA standards, based on the requirements of ISO 5167, AGA Report Number 3 and ASME MFC 3M. Another contribution comes from Computational Fluid Dynamics (CFD) simulations and analyses. Their results show, for example, that the deviation of the discharge coefficient does not exceed 2 % of the value of standardised solutions.
Optimised to customer requirements
Our multi-hole orifice plates are suitable for liquid, gas and steam flow measurement and optimised with respect to customers’ requirements to perfectly match the respective final application. The bore diameters are calculated to generate the specified differential pressure at full scale flow rate.
