20种液位计工作原理及常见故障分析
20种液位计工作原理及常见故障分析3、钢带液位计它是利用力学平衡原理设计制作的。
当液位改变时，原有的力学平衡在浮子受浮力的扰动下，将通过钢带的移动达到新的平衡。
液位检测装置（浮子）根据液位的情况带动钢带移动，位移传动系统通过钢带的移动策动传动销转动，进而作用于计数器来显示液位的情况。
4、雷达液位计雷达液位计是基于时间行程原理的测量仪表，雷达波以光速运行，运行时间可以通过电子部件被转换成物位信号。
探头发出高频脉冲并沿缆式探头传播，当脉冲遇到物料表面时反射回来被仪表内的接收器接收，并将距离信号转化为物位信号。
5、磁致伸缩液位计磁致伸缩液位计的传感器工作时，传感器的电路部分将在波导丝上激励出脉冲电流，该电流沿波导丝传播时会在波导丝的周围产生脉冲电流磁场。
在磁致伸缩液位计的传感器测杆外配有一浮子，此浮子可以沿测杆随液位的变化而上下移动。
在浮子内部有一组永久磁环。
当脉冲电流磁场与浮子产生的磁环磁场相遇时，浮子周围的磁场发生改变从而使得由磁致伸缩材料做成的波导丝在浮子所在的位置产生一个扭转波脉冲，这个脉冲以固定的速度沿波导丝传回并由检出机构检出。
通过测量脉冲电流与扭转波的时间差可以精确地确定浮子所在的位置，即液面的位置。
6、射频导纳液位计射频导纳料位仪由传感器和控制仪表组成，传感器可采用棒式、同轴或缆式探极安装于仓顶。
传感器中的脉冲卡可以把物位变化转换为脉冲信号送给控制仪表，控制仪表经运算处理后转换为工程量显示出来，从而实现了物位的连续测量。
7、音叉物位计音叉式物位控制器的工作原理是通过安装在音叉基座上的一对压电晶体使音叉在一定共振频率下振动。
当音叉与被测介质相接触时，音叉的频率和振幅将改变，这些变化由智能电路来进行检测，处理并将之转换为一个开关信号。
8、玻璃板液位计（玻璃管液位计）玻璃板式液位计是通过法兰与容器连接构成连通器，透过玻璃板可直接读得容器内液位的高度。
9、压力液位变送器压力式液位计采用静压测量原理，当液位变送器投入到被测液体中某一深度时，传感器迎液面受到的压力的同时，通过导气不锈钢将液体的压力引入到传感器的正压腔，再将液面上的大气压Po 与传感器的负压腔相连，以抵消传感器背面的Po ，使传感器测得压力为：ρ .g.H ，通过测取压力P ，可以得到液位深度。
