浮筒液位计测量原理，西安华恒仪表介绍：浮筒液位计是根据阿基米德定律和磁耦合原理设计而成的液位测量仪表，仪表可用来测量液位、界位和密度，负责上下限位报警信号输出。专用于测量压力容器内液位，由四个基本部分组成：浮筒、弹簧、磁钢室和指示器。
Float level gauge measuring principle,Xi'an Huaheng Instrument:Float level gauge is designed according to Archimedes law and magnetic coupling principle.The instrument can be used to measure liquid level,boundary level and density,responsible for the output of upper and lower limit alarm signal.It is specially designed for measuring liquid level in pressure vessel.It consists of four basic parts:buoy,spring,magnet chamber and indicator.
原理：
Principle:
浸在液体中的浮筒受到向下的重力，向上的浮力和弹簧弹力的复合作用。当这三个力达到平衡时，浮筒就静止在某一位置。当液位发生变化时，浮筒所受浮力相应改变，平衡状态被打破，从而引起弹力变化即弹簧的伸缩，以达到新的平衡。弹簧的伸缩使其与刚性连接的磁钢产生位移。
The buoy immersed in liquid is subjected to the combined action of downward gravity,upward buoyancy and spring elasticity.When these three forces are balanced,the buoy is stationary at a certain position.When the liquid level changes,the buoyancy of the buoy changes correspondingly,and the equilibrium state is broken,which causes the elastic change,i.e.the expansion and contraction of the spring,in order to achieve a new balance.The expansion of the spring displaces the rigidly connected magnet.
这样，通过指示器内磁感应元件和传动装置使其指示出液位。限位开关的仪表即可实现液位信号的报警功能。
In this way,the liquid level is indicated by the magnetic induction element and the transmission device in the indicator.The instrument of limit switch can realize alarm function of liquid level signal.
基于位移测量原理，悬挂在测量弹簧上的位移筒体沉浸在被测液体中，并受到阿基米德向上浮力作用，其作用力与排开液体质量成正比。根据液位高低，筒体浸入深度不同，向上浮力发生变化，测量弹簧将要作相应延伸，以达到测量结果。
Based on the principle of displacement measurement,the displacement cylinder suspended on the measuring spring is immersed in the measured liquid and acted by Archimedes upward buoyancy,whose force is proportional to the mass of the discharged liquid.According to the liquid level and the depth of immersion,the buoyancy of the cylinder will change.The measuring spring will be extended accordingly to achieve the measurement results.
