概述：

       玻璃管浮子流量计的测量部分为一根垂直安装的锥形玻璃管及在内可以上下移动的浮子所组成，锥管在端向上，当流体自下而上流经玻璃管时，在浮子上、下之间产生压差，浮子在此差压作用下上升。当使浮子上升的力与浮子所受的重力，浮子及粘性力三者的合力相等时，浮子处于平衡位置。因此，流经流量计的流体流量与浮子上升高度存在着一定关系，浮子的平衡位置可作为流量的量度。

优点：

       ● 易于安装和服务；
       ● 结构坚固；
       ● 易于维护；
       ● 限位开关可选；
       ● 没有易损件；
       ● 带碎片保护功能。

应用：

       ● 精准测量；
       ● 气相色谱分析；
       ● 微小流量监控；
       ● 可以与不同的压力调节器连接，以能让出口或入口的压力稳定。

液位浮子

液位浮子（也称浮球）是液位测量与控制系统中核心的感应元件。其工作原理基于阿基米德浮力原理，当液位变化时，浮子会随之升降，从而将液位变化转换为机械位移或磁力信号，进而触发开关动作或驱动指示装置。

液位浮子通常根据其功能分为浮球开关和磁性浮子两大类。浮球开关通过浮子的位移直接驱动内部的微动开关，输出开关信号；而磁性浮子则与磁性液位计配套使用，通过磁耦合原理无接触地驱动外部指示器翻柱翻转或触发干簧管开关。

该产品具有结构简单、性能稳定、安装方便、成本低廉等优点，是工业领域中常见和基础的液位传感解决方案之一。

广泛应用于供水、排水、水处理、石油化工、制药、食品、锅炉、制冷设备等行业，用于水箱、水池、油箱、压力容器等设备的液位自动控制、报警或指示。

Level Float Product Overview

The level float (also called a float ball float switch) is the core sensing component in level measurement control systems. Its operation is based on Archimedes' principle of buoyancy. As the liquid level changes, the float moves up down accordingly, converting this level change into either mechanical displacement a magnetic signal, which in turn activates a switch drives an indicating device.

Level floats are generally categorized into two main types based on their function: float switches magnetic floats. Float switches use the displacement of the float to directly actuate an internal micro-switch, providing an on/off signal. Magnetic floats are used with magnetic level indicators (magmeters), they utilize magnetic coupling to non-contact drive the external indicator's flags to flip activate reed switches.

This product offers the advantages of simple structure, stable performance, easy installation, low cost, making it one of the most common fundamental liquid level sensing solutions in industrial fields.

Key Features:

Simple Working Principle: Based on fundamental buoyancy, ensuring high reliability.

Strong Adaptability: Can be constructed various materials (e.g., Stainless Steel, PP, PVDF) to suit different liquid media, including water, oil, acids, alkalis, corrosive liquids.

Multiple Functions: Can be used for simple point level control (ON/OFF), as well as continuous level indication remote transmission.

Diverse Structures: Available in various forms such as hollow balls solid floats to meet the requirements of different liquid densities installation spaces.

Typical Applications:

Widely used in water supply, drainage, water treatment, petrochemical, pharmaceutical, food beverage, boiler, refrigeration systems for automatic level control, alarm, indication in tanks, sumps, oil reservoirs, pressure vessels, other equipment.
