Main advantages of technical parameters of metal float flowmeter

The metal tube float flowmeter, also known as the metal tube rotor flowmeter, is a reliable and versatile device widely used in industrial applications. It features a simple design, high accuracy, easy installation, low maintenance, long service life, and excellent performance under high temperature and pressure conditions. Its robust structure ensures safety and stability, making it ideal for measuring the flow of non-transparent or corrosive media, as well as for low-flow and small-bore applications. Unlike other flowmeters, it does not require straight pipe sections before or after the meter, offering greater flexibility during installation. The flowmeter is equipped with a large dual-line liquid crystal display, allowing on-site viewing of both instantaneous and accumulated flow data. It includes a backlit single-axis indicator for clear readings and uses non-contact magnetic coupling to ensure accurate and stable signal transmission. The fully metallic construction makes it suitable for harsh environments, including high-temperature, high-pressure, and highly corrosive media. It can also be used in flammable and explosive areas, ensuring safe operation in critical situations. Available in multiple power supply options—two-wire system, battery, or AC power—the flowmeter supports multi-parameter calibration and offers data recovery, backup, and power-down protection functions. These features enhance its reliability and usability in various industrial settings. One of the key technical advantages of the metal tube float flowmeter is its "V" shaped body design, which eliminates stagnant zones and prevents blockages in the system. It is particularly suitable for high-viscosity fluids, low Reynolds number flows, and media containing suspended particles or bubbles. The device maintains a square relationship between differential pressure and flow rate even at low Reynolds numbers (as low as 500), ensuring consistent performance across a wide range of flow conditions. Its measurement accuracy is unaffected by the dielectric constant of the fluid, and it can output a 4-20 mA electrical signal compatible with various instruments. It also features advanced functions such as viscosity, temperature, and density compensation, along with resistance to vibration, shock, dirt, corrosion, and explosion hazards. It supports bidirectional flow measurement and offers excellent long-term stability, with a near-zero failure rate over time. With no moving parts and no wear, the metal tube float flowmeter requires no recalibration during long-term use. It delivers high measurement accuracy, with extended uncertainty ranging from ±0.5% to ±0.2% (depending on water or oil calibration). It can be easily expanded by replacing the float, allowing for increased measurement range without the need for a full system replacement. Available in different models, the standard type offers a range ratio of 1:3 with a nonlinear error of ≤±1%, while the high-performance version provides a wider range ratio of 1:10 and improved accuracy (±0.5% to ±0.2%). The flowmeter is constructed entirely from stainless steel, ensuring durability and resistance to corrosion.
