YK-FR. Multi-Hole Orifice Flowmeter (Balanced Flowmeter)
YK-FR Multi-Hole Orifice Plate (also known as a Balanced Flowmeter) is a new type of differential pressure flow sensing device developed in accordance with GB2624 standards, based on the standard orifice plate and flow conditioner. It is designed to deliver excellent performance while requiring minimal upstream and downstream straight pipe lengths. YK-FR Multi-Hole Orifice Plate significantly improves traditional throttling devices by providing flow field conditioning and balancing capabilities. Conventional throttling devices use a single orifice, which disrupts the ideal flow profile after throttling. In contrast, the balanced flowmeter features multiple flow passages that optimize and stabilize the flow profile toward an ideal condition. Therefore, it is also known as a balanced or conditioning-type flowmeter, maximizing the advantages of differential pressure flow measurement. It is suitable for flow measurement of nearly all types of fluids.

Product Principle
YK-FR Multi-hole Orifice Plate (also known as the Balanced Flowmeter) is a differential pressure flow sensor. It features a flow-conditioning orifice design that enables reliable operation even under disturbed upstream flow conditions. Balanced flow meters are based on energy conversion principles in closed conduits: for ideal fluids, flow rate is proportional to the square root of the differential pressure; by measuring this ΔP and applying Bernoulli’s equation, volumetric or mass flow can be calculated; the balanced flow sensor features a multi-hole disk installed across the pipe cross-section, where each “function hole” is precisely sized and positioned according to proprietary formulas and test data; as fluid passes through these holes, it becomes uniformly distributed and rectified, minimizing vortices and approximating ideal flow, thereby generating a stable differential pressure signal via tapping ports for highly accurate flow computation.
