2. Advantages and disadvantages of metal float flowmeter
Metal float flowmeter exhibits significant advantages in specific application scenarios. Suitable for situations with small pipe diameters and low flow velocities, such as equipment with a diameter of 1.5-4mm, it can measure liquid flow velocities of 0.2-0.6m/s (or even lower), while metal tube float flowmeters with a diameter greater than 15mm are suitable for flow velocity ranges of 0.5-1.5m/s. It exhibits viscosity insensitivity for flow measurements at lower Reynolds numbers. When the Reynolds number at the flow annulus is greater than 40 or 500, the flow coefficient remains stable and is not affected by changes in fluid viscosity. This makes the performance of the metal float blind flowmeter better than other throttling differential pressure instruments such as standard orifice plates under low Reynolds number conditions, and its minimum required Reynolds number is much lower than the latter. Float flow meters have a relatively tolerant demand for upstream straight pipe sections, reducing installation complexity. It has a wide flow range, generally 10:1, with a minimum of 5:1 and a maximum of 25:1. The output of the flow detection element is close to linear, and the pressure loss is small, which increases its flexibility and efficiency in use. The glass tube float flowmeter, due to its simple structure and affordable price, is easy to indicate flow on site, but there is a risk of glass tube fragility, especially in gas measurement without guiding structures. In contrast, metal tube float flowmeters have a wider range of temperature and pressure applications, avoiding the problem of cone tube rupture. Howe
3. Working principle of metal tube float flowmeter
The working principle of metal tube float flowmeter is to indirectly measure the flow velocity or flow rate of the fluid by observing the position of the float in the fluid.
. The following is its detailed working principle and composition:1. Structure Composition: The metal tube float flowmeter mainly consists of the following parts: Metal pipeline: As a channel for fluid flow, it is usually made of stainless steel or other corrosion-resistant metals to ensure stability and durability under harsh working conditions. Float: An object with a density lower than that of the fluid being measured, capable of freely moving up and down in the fluid. The shape and size of the float have been carefully designed to ensure that it accurately reflects the flow velocity and flow rate of the fluid. Dial or ruler: used to mark the range of flow, usually located on the outside of metal pipes for easy observation. Reading pointer: connected to the float, used to indicate the position of the float on the dial or ruler, thereby reading the corresponding flow value.
2. Working principle: Fluid flow: When fluid flows through a metal pipeline, a certain driving force is generated.
