Applicable Working Conditions of Balanced Flowmeters
Balanced flowmeters are a new type of high-precision differential pressure flow measuring device optimized based on traditional throttling principles. Featuring multi-hole balanced throttling, uniform flow field distribution, ultra-low straight pipe section requirements, and stable differential pressure signals, they are widely applied in complex and high-precision industrial flow measurement scenarios.
Firstly, balanced flowmeters are perfectly suitable for limited installation space and complex pipeline conditions. Different from conventional throttling devices that require long front and rear straight pipe sections, they can rectify turbulent flow, swirling flow and asymmetric flow fields independently, enabling accurate measurement even after elbows, valves and tees. This makes them ideal for compact equipment skids and reconstructed old pipelines.
Secondly, they adapt to high-precision metering working conditions for gas, liquid and steam. With a wider turndown ratio and better repeatability than orifice plates and V-cone flowmeters, they are commonly used for precise measurement of natural gas, compressed air, boiler steam and process medium in power, petrochemical and energy metering systems.
In addition, balanced flowmeters work stably under high temperature, high pressure and high flow velocity working conditions. The integral symmetrical throttling structure effectively reduces local abrasion and pressure loss, resisting impact from high-speed fluid. They are applicable to superheated steam, high-pressure process fluid and other harsh working conditions that require long-term stable operation.
Moreover, they can measure slightly dirty media with trace impurities. The multi-hole balanced structure avoids concentrated impurity deposition, reducing blocking risks compared with traditional orifice plates. It is suitable for low-contamination industrial fluids that require continuous and uninterrupted monitoring.
In summary, balanced flowmeters stand out in working conditions with strict precision requirements, insufficient straight pipe sections, harsh temperature and pressure environments, and slight medium impurities, serving as an upgraded alternative to traditional differential pressure flowmeters.
