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。

Parker Hannifin Corporation 仪表管筒选择指南说明书
Instrument TubingSelection GuideBulletin 4200-TSOctober 2000Parker Hannifin Corporation Instrum entation Connectors Division P.O. B ox 400004, H untsville, A L 35815-1504Parker’s instrument tube fittings have been designed to work in a wide variety of applications that demand the utmost in product performance. Although Parker’s Instrument tube fittings have been engineered and manufactured to consistently provide this level of reliability, no systems in-tegrity is complete without considering the critical link, tubing.This booklet is intended to assist the designer to properly select and order quality tubing.Proper tube selection and installa-tion, we believe, are key ingredients in building leak-free reliable tubingsystems.General Selection CriteriaThe most important consideration inthe selection of suitable tubing for anyapplication is the compatibility of thetubing material with the media to becontained. Table 1 lists commonmaterials and their associated generalapplication. Table 1 also lists themaximum and minimum operatingtemperature for the various tubingmaterials.In addition, Parker instrumentfittings are designed to work onlike materials. Stainless steelfittings should be used only withstainless steel tubing, aluminumfittings with aluminum tubing, etc.The practice of mixing materials isstrongly discouraged. The onlyexception is brass fittings withcopper tubing.Dissimilar materials in contactmay be susceptible to galvaniccorrosion. Further, differentmaterials have different levels ofhardness, and can adversely affectthe fittings ability to seal on thetubing.TUBINGMATERIAL GENERAL APPLICATION RECOMMENDED TEMPERATURE RANGEStainless Steel High Pressure, High Temperature,Generally Corrosive Media -425°F to 1200°F1 (-255°C to 605°C)Carbon Steel High Pressure, High Temperature Oil,Air, Some Specialty Chemicals -65°F to 800°F2 (-55°C to 425°C)Copper Low Temperature, Low Pressure Water,Oil, Air-40°F to 400°F (-40°C to 205°C)Aluminum Low Temperature, Low Pressure Water,Oil, Air, Some Specialty Chemicals-40°F to 400°F (-40°C to 205°C)Monel 400 Recommended for Sour Gas Applications.Well Suited for Marine and General ChemicalProcessing Applications-400°F to 800°F (-240°C to 425°C)Alloy C276Excellent Corrosion Resistance to Both OxidizingAnd Reducing Media and Excellent Resistance toLocalized Corrosion Attack -320°F to 1000°F (-195°C to 535°C)Carpenter 20 Applications Requiring Resistance to StressCorrosion Cracking in Extreme Conditions-400°F to 800°F (-240°C to 425°C)Alloy 600Recommended for High Temperature ApplicationsWith Generally Corrosive Media -205°F to 1200°F (-130°C to 650°C)Titanium Resistant To Many Natural Environments Such asSea Water, Body Fluids and Salt Solutions-320°F to 600°F (-195°C to 315°C)Carpenter 20 is a trademark of Carpenter Technology Corporation.Monel 400 is a trademark of International Nickel.1. F or operating temperatures above 800°F(425°C), consideration should be given to media. 300 Series Stainless Steels are susceptible to carbide precipitation which may lead to intergranular corrosion at elevated temperatures.2. C onsideration should be given to maximum temperature ratings if fittings and/or tubing are coated or plated.All temperature ratings based on maximum temperatures per ASME/ANSI B31.3 Chemical Plant And Refinery Piping Code, 1999 Edition.The information listed in Table 1 is general in scope. For specific applications, please contact Parker’s Instrumentation Connectors Division, Product Engineering Department (256) 881-2040.TABLE 1Gas ServiceSpecial care must be taken when selecting tubing for gas service. In order to achieve a gas-tight seal, ferrules in instrument fittings must seal any surface imperfections. This is accomplished by the ferrules penetrating the surface of the tubing. Penetration can only be achieved if the tubing provides radial resistance and if the tubing material is softer than the ferrules.Thick walled tubing helps to provide resistance. Tables 2-7 indicate the minimum acceptable wall thickness for various materials in gas service. The ratings in white indicate combination of diameter and wall thickness which are suitable for gas service.Acceptable tubing hardness for general application is listed in Table 9. These values are the maximum allowed by ASTM. For gas service, better results can be obtained by using tubing well below this maximum hardness. For example, a desirable hardness of 80 Rb is suitable for stainless steel. The maximum allowed by ASTM is 90 Rb. System PressureThe system operating pressure is another important factor in determining the type, and more importantly, the size of tubing to be used. In general, high pressure installations require strong materials such as steel or stainless steel. Heavy walled softer tubing such as copper may be used if chemical compatibility exists with the media. However, the higher strength of steel or stainless steel permits the use of thinner tubes without reducing the ultimate rating of the system.

液位计工作原理与结构
玻璃管式液位计工作原理与结构仪表是基于连通器原理设计的，由玻璃管构成的液体通路。
通路经接管用法兰或锥管螺纹与被测容器连接构成连通器，透过玻璃管观察到的液面与容器内的液面相同即液位高度。
管式液位计主要由玻璃管、保护套、上下阀门及连接法兰（或螺纹）等组成。
液位计改变零件的材料或增加一些附属部件，即可达到防腐或保温的功能。
●适用范围及特点我公司是物位仪表的专业生产企业，生产的玻璃板式、玻璃管式液位计已有多年的历史、工艺先进，检测设备齐全，产品符合机械部专业标准及化工部专业标准，产品型式多样。
具有结构简单、经济实用、安装方便、工作可靠、使用寿命长等优点。
作为基本的液位指示仪表，广泛运用于在最简单液位测量场合和自动化程度很高的大型工程项目中液位的测量和监测。
●主要技术参数：公称长度：500，600，800，1000，1100，1200，1400mm工作压力： 1.6MPa介质温度：0～200℃针型阀自动关闭压力：≤0.2MPa伴热管工作压力：0.6MpaUHZ-10系列磁翻板液位计工作原理UHZ-10系列磁翻板液位计是北京金德创业测控技术有限公司在引进、改进国外同类液位计，结合本公司此类液位计长期销售中取得的经验的基础上，依照化工工业部标准HG/T21584-95开发、研制出的最新产品。
为保证产品的可靠性和技术上的优势，该仪表的所有关键部位均采用优质原材料或进口元器件。
该产品完全可代替国外同一类型产品，性能可靠、安全、实用，可适应对高温、高压、腐蚀性液位的测量。
工作原理金德公司UHZ-10系列磁翻板液位计可以视为压力容器的一部分。
以UHZ-10系列侧装式磁翻板液位计为例，液位计与容器通过侧法兰相连接，这样液位计中的变化实际与容器内液位变化是相一致的。
液位计腔内的柱状浮子与液位计外部的磁翻板和一关实际为一组磁性系统。
柱状浮子通过磁场影响翻板内的翻珠和开关内的磁性元件，从而将液位传递出去。
磁翻板是显示液位的部分。
外测液位计与外测液位开关技术规格详解
西安定华外贴液位计技术规格详解一、ELL-FI外贴液位计（一）、规格1、ELL-FI-A标准型（经典型）用于30m量程内各种罐型的常规工况。
可内调或外调阀值，不能调频。
2、ELL-FI-B增强型（极品型）不仅可用于30m量程内各种罐型的常规工况，而且可用于30m量程内各种罐型的严苛工况。
阀值、频率可根据现场工况外调。
3、ELL-FI-P紧凑型（经济型）用于16m量程内卧罐和立罐。
可内调阀值，不能调频。
4、ELL-FI-V车载型（抗震性）适用于6m量程内油罐车、化学液体运输车辆。
可内调阀值，不能调频。
（二）、测量精度1、仪表的测量精度通常以最大允许的绝对误差或相对误差表示。
以绝对误差表示精度等级，例如液位计精度等级1mm、5mm、10mm；以相对误差表示精度等级，例如液位计精度等级0.5%F.S.、0.2% F.S.、0.1% F.S.F.S.=Full Scale 表示额定检测距离的范围。
F.S. 表示满量程。
%F.S是指传感器的指标相对于传感器的满量程误差的百分数2、绝对误差和相对误差的换算相对误差=绝对误差/满量程×%3、几个定义绝对误差：一个量的观测值或计算值与其真实值（真值）之差。
误差是不可避免的，只能减小。
真值：是一个变量本身所具有的真实值，它是一个理想的概念，一般是无法得到的。
所以在计算误差时，一般用约定真值或相对真值来代替。
约定真值也称规定真值，是一个接近真值的值，它与真值之差可忽略不计。
绝对误差并不能完全表示近似值的好坏程度，例如：x=10±1，y=1000±5，哪一个精度高呢？看上去x的绝对误差限比y的绝对误差限小，似乎x的精度高，其实不然。
绝对误差计算公式:测量值-真实。
绝对误差有正负之分的。
相对误差：指的是测量所造成的绝对误差与被测量〔约定〕真值之比。
乘以100%所得的数值，以百分数表示。
一般来说，相对误差更能反映测量的可信程度。
相对误差等于测量值与真值差的绝对值除以真值，再乘以100%。
