YUNYI orifice plate flowmeter is a differential pressure flow measurement instrument based on Bernoulli’s equation and the principle of fluid continuity. Its core component is a throttling device (orifice plate) with a central opening installed in the pipeline. When fluid flows through the orifice plate, a static pressure difference (differential pressure value) is generated between its upstream and downstream sides. This differential pressure value is proportional to the square of the fluid’s velocity (i.e., flow rate). By measuring and calculating this differential pressure value using a matched differential pressure transmitter, pressure transmitter, and temperature sensor (for temperature and pressure compensation), the fluid flow rate can be precisely determined. As the oldest, most thoroughly researched, and most standardized flow meter, it has established an unshakable position in industrial measurement due to its simple structure, rugged durability, and low cost. Product Advantages The core value of the orifice plate flowmeter lies in its unparalleled simplicity, reliability, and extremely low acquisition cost, coupled with outstanding performance under high-pressure and high-temperature conditions. 1. Simple Structure, Robust and Reliable: With no moving parts, it consists solely of an orifice plate, pressure tapping device, and flanges. It withstands high temperatures, high pressures, and strong vibrations, delivering exceptionally stable performance and an extremely long service life with virtually no maintenance required. 2. Exceptionally Cost-Effective: Initial purchase and installation costs are significantly lower than most other flowmeter types.
