1、 Core Measurement Principles
Liaoning Xinruipeng Environmental Protection Rotary Flow Meter is based on the core measurement principle of constant pressure difference and variable throttling area. It belongs to the variable area flow meter, and its working mechanism has been specially optimized for environmental protection conditions to adapt to various complex media and harsh environments. The core structure of the product consists of a conical measuring tube, a float (rotor), a guiding device, and a display module. The edge of the float is engraved with an inclined groove and equipped with a guiding core rod. When the fluid flows through the inclined groove, a reverse thrust is generated to rotate the float, effectively avoiding eccentricity and ensuring measurement stability.
When the measured medium (liquid or gas) flows through the conical measuring tube from bottom to top, a pressure difference is formed before and after the float, which exerts an upward thrust on the float; At the same time, the float is subjected to the difference between downward gravity and buoyancy. When the two forces reach equilibrium, the float will stabilize at a specific position. Due to the gradual expansion of the inner diameter of the conical tube from top to bottom, the cross-sectional area of the annular channel where the float is located corresponds one-to-one with the medium flow rate. By accurately capturing the displacement of the float and converting the internal signal, accurate flow data can be output in real time [1].
In response to common corrosive media and fluids containing trace impurities in the environmental protection industry, Xinruipeng has optimized the measurement principle in a targeted manner. By optimizing the float density and cone tube angle, the equipment's adaptability to different viscosities and corrosive media has been improved, while reducing the impact of impurities on measurement accuracy, ensuring stable and accurate measurement in media such as sewage, acid-base solutions, and exhaust gases. In addition, the product supports two installation methods: vertical and horizontal. The horizontal installation model is equipped with a special angle cone tube to counteract the influence of gravity force and adapt to environmentally friendly working conditions with limited space.
