A+KThe core design of the ring wedge flowmeter is based onPrinciple of porous equilibrium throttlingThe sensor is a symmetrically distributed function hole disk structure. Unlike traditional single orifice throttling devices, this design decomposes the fluid into multiple parallel streams by optimizing the aperture size, distribution angle, and arrangement density, making the flow field distribution more uniform. When the medium passes through the disk, the turbulent shear force and vortex intensity are significantly reduced, and the flow field stability is improved, thereby reducing signal noise and pressure fluctuations.

In addition,A+KThe ring wedge flowmeter adopts redundant pressure measurement technology, with multiple sets of pressure measurement holes set before and after the sensor. Multiple sets of pressure data are synchronously collected through differential pressure transmitters, and the average value is output after algorithm correction. This design not only improves measurement accuracy, but also effectively identifies single point pressure faults, ensuring data reliability. For example, when measuring slurry containing solid particles, redundant pressure measurement can avoid measurement deviation caused by local blockage.
