结构原理

液位计根据浮力原理和磁性耦合作用研制而成。当被测容器 中的液位升降时，液位计本

体管中的磁性浮子也随之升降，浮子 内的永久磁钢通过磁耦合传递到磁翻柱指示器，驱动红、白翻柱 翻转180°，当液位上升时翻柱由白色转变为红色，当液位下降时翻柱由红色转变为白色，指示器的红白交界处为容器内部液位的实际高度，从而实现液位清晰的指示。

磁性浮子液位计
它是利用磁耦合原理进行工作的,产品弥补了玻璃管液位计不能在高温高压下工作且易碎的多重缺点.　有侧装和顶装二种安装方式,无论那种方式都可以捆绑远传装置,使液位计即可以就地显示液位,又可以远程监控液位.捆绑后的磁翻板液位计可称为远传型磁翻板液位计.　制作磁翻板液位计的工艺虽然很简单,但磁翻板液位计作为计量仪表,特别是远传型磁翻板液位计，如果未经质监局审核,没有生产许可证,产品质量是难以得到保证的.因此,采购磁翻板液位计要选择有生产许可证且信誉好的厂家,价格可能略高一点,但产品质量有保证,售后服务有保证。　磁性液位计的使用　玻璃板液位计可直接用来观察各种容器内介质的液位高度。它适用于石油、化工等工业领域的液位指示，该液位计结构简单，观察直观、清晰，不堵塞、不渗漏，安装方便，维修简单。玻璃板液位计上、下端安装法兰与容器相连接构成连通器，透过玻璃板可直接观察到容器内液位的实际高度。上下阀门装有安全钢珠，当玻璃因意外损坏时，钢珠在容器内压的作用下自动密封，防止容器内液体外溢，并保证操作人员安全。翻柱侧装式磁性液位计
磁性浮子式液面计安装于桶槽外侧延伸管上，桶槽内部的液位能由翻板指示器清楚得知。旁路管外侧亦可加装磁性开关，做为电气接点信号输出，或装置液位传送器做远距离液位信号传送及液位控制。该液位计是具有可靠的安全性仪表。由于具有磁性藕合隔离器密闭结构。尤其适用于易燃、易爆和腐蚀有毒液位检测。从而使原复杂环境的液位检测手段变得简单和可靠安全。液位计具有就地显示的直读式特性。不需多组液位计组合。有着单体进行全量程测量。设备少开孔，显示清晰，标志醒目，读数直观等优点。当液位计直接配带显示仪时可省去该系统信号检测的中间变送从而提高其传输精度。　选择磁性液位计应该考虑的因素　选择液位计时应考虑以下因素：(1)测量对象，如被测介质的物理和化学性质，以及工作压力和温度、安装条件、液位变化的速度等；(2)测量和控制要求，如测量范围、测量(或控制)精确度、显示方式、现场指示、远距离指示、与计算机的接口、安全防腐、可靠性及施工方便性。　给水工程中常用的液位计及选型要点如下：　a. 浮球式液位计　在液体中放入一个空心的浮球，当液位变化时，浮球将产生与液位变化相同的位移。可用机械或电的方法来测得浮球的位移，其精确度为±(1~2)%，这种液位计不适用于高粘度的液体，其输出端有开关控制和连续输出。　在净水厂的设计中，多将此种液位计用于集水井的液位测量以控制排水泵的自动开停。　b.静压(或差压)式液位计　由于液柱的静压与液位成正比，因此利用压力表测量基准面上液柱的静压就可测得液位。根据被测介质的密度及液体测量范围计算出压力或压差范围，再选用量程、精确度等性能合适的压力表或差压表。这种液位计的精确度为±(0.5~2)%。　c. 电容式液位计　在容器内插入电极，当液位变化时，电极内部介质改变，电极间(或电极与容器壁之间)的电容也随之变化，该电容量的变化再转换成标准化的直流电信号。其精确度为±(0.5~1.5)%。　电容式液位计具有以下优点：传感器无机械可动部分，结构简单、可靠；精确度高；检测端消耗电能小，动态响应快；维护方便，寿命长。缺点是被测液体的介电常数不稳定会引起误差。电容式液位计一般用于调节池、清水池等的液位测量。　当测量范围不超过2m时，采用棒状、板状、同轴电极；当超过2m时，采用缆式电极。当被测介质为水时，采用带绝缘层(可用聚乙烯)的电极。　d. 超声液位计　超声液位计的传感器由一对发射、接收换能器组成。发射换能器面对液面发射超声波脉冲，超声波脉冲从液面上反射回来，被接收换能器接收。根据发射至接收的时间可确定传感器与液面之间的距离，即可换算成液位。其精确度为±0.5%。　这种液位计无机械可动部分，可靠性高，安装简单、方便，属于非接触测量，且不受液体的粘度、密度等影响，因此多用于药池、药罐、排泥水池等的液位测量。但此种方法有一定的盲区，且价格较贵。　另外楼主讲到磁翻板液位计，要考虑磁性材料的退磁问题，退磁导致液位计不能正常工作，测量结果也不能为操作人员信任。磁翻板液位计推荐选用的场合：高处不轻易接近读取液位的场所，例如塔等。但不能只设置磁翻板液位计，要同时设置玻璃板液位计，磁翻板液位计只能做参考用。另外较重要的液位（与工艺安全、设备安全相关）例如，汽包液位，不推荐用磁翻板液位计。　磁翻板液位计还要考虑介质的腐蚀性和使用寿命，因为磁翻板是工艺介质里装有磁性浮筒，浮筒耐腐蚀性和厚度也要考虑！

Magnetic float level gauge

It is to work with magnetic coupling principle, products make up the multiple disadvantagesmeter cannot work under high temperature and high pressure and fragile glass liquid leveltube. Fitted with side and top two installed, regardless of the way you can bundle remote transmission device, the liquid level meter which can display the liquid level on the spot, andcan remotely monitor the liquid level. After the bundle magnetic level gauge can be called the remote type magnetic level gauge. The manufacture process of the magnetic level gaugealthough very simple, but the magnetic level gauge as measuring instruments, especially the remote type magnetic level gauge, if not the Quality Supervision Bureau, audit, no production license, the quality of the products is difficult to be guaranteed. Therefore, the procurement of magnetic level gauge to choose to have the production license and good reputation of the manufacturers, the price may be slightly higher, but ensures the product quality, after saleservice guarantee. The use of glass plate level gauge magnetic level gauge can be used to directly observe the medium container liquid level height. It is suitable for liquid level ofindustrial field of petroleum, chemical and other instructions, the liquid level meter has the advantages of simple structure, visual observation, clear, no blockage, no leakage,convenient installation, simple repair. Glass plate level gauge is arranged at the lower end ofthe flange, and connected connected device, can be directly observed the actual height ofthe liquid level through the glass plate. The upper and lower valve is provided with a safetyball, when the glass due to accidental damage, ball in the pressure within the containerautomatically under the effect of sealing, prevent the liquid in the container spillover, and ensure the safety of personnel. Turning column side mounted magnetic level gauge

Magnetic float type liquid level gauge is installed on the barrel groove of the outer extensiontube, liquid level in tank by internal plate turning indicator can clearly know. Bypass pipe can also be installed outside the magnetic switch, as the electrical contact signal output, or device of liquid level transmitter do remote level signal transmission and liquid level control. The liquid level gauge has the instrument is reliable safety. Because of the magnetic coupledisolator sealed structure. Especially for flammable, explosive and corrosive toxic liquid level detection. So that the liquid level detecting means of the original complex environment has become simple and reliable safety. Liquid level meter has the characteristics of in-situ direct reading display. No more group level meter combination. There is a single full rangemeasurement. Equipment small hole, clear display, eye-catching signs, visual reading etc..When the liquid level gauge is directly equipped with display instrument can save theintermediate signal detection and transmission system so as to improve the transmissionaccuracy. Factor in the selection of magnetic level gauge should be given the option of level meter should consider the following factors: (1) the object of measurement, such as physical and chemical properties of the medium to be measured, and the working pressure and temperature, the installation conditions, the variation of the liquid level speed; (2)measurement and control requirements, such as the measurement range and measurement(or control) precision, display mode, spot indication and remote indication, and computer interface, safety, reliability and ease of construction anti-corrosion. The following water supply engineering are commonly used in liquid level meter and selection points: float in the liquid into a hollow A. float type liquid level gauge, when the liquid level changes, the float ball will generate the same displacement and the change of liquid level. Displacement method can be used to measure mechanical or electrical floating ball, its accuracy is + (1~2)%, the liquid level gauge is not suitable for high viscosity liquid, its output end is provided with a switch control and continuous output. In the design of waterworks, many will automatically start stopthe liquid level gauge for measuring level set of wells to control the drainage pump. B. static pressure (or pressure) type liquid level gauge because of the liquid column hydrostatic pressure and liquid level is proportional to, so using pressure gauge measurement datumstatic liquid column on the surface can be measured the level. According to the density and liquid measurement range of measured medium to calculate the pressure or differential pressure range, and then choose the range and accuracy properties suitable pressure gauge or pressure gauge. The liquid level meter accuracy is + (0.5~2)%. C. capacitance type liquid level gauge is inserted into the electrode in a container, when the liquid level changes,the internal medium between electrodes, electrode change (or between the electrode and the wall of the container) capacitor is also changing, change the capacitance is converted intoDC signal standardization. Its accuracy is + (0.5~1.5)%. Capacitance type liquid level gaugehas the following advantages: the sensor has no mechanical moving part, simple and reliablestructure; high precision; detection end electric energy consumption is small, fast dynamic response and convenient maintenance, long service life. The disadvantage is the dielectric constant of the liquid to be tested will cause instability in error. Capacitance type liquid level gauge is generally used for liquid level measurement adjustment pool, water pool etc.. When the measurement range is not more than 2m, uses the rod, plate, a coaxial electrode; whenmore than 2m, the cable type electrode. When the measured medium is water, mining
