LevelSite 磁性浮球液位计说明书
Level1LevelSite ® Supplemental GuideFeaturesModel LSSMin Typical SystemFigure 12from the liquid; the tank remains sealed from the surrounding environment (See Figure 2). Accidental spills from sight-glass breakage are eliminated.LevelSite® consists of 3 major components: the float housing, a magnetic float, and the rotating flagassembly. The float housing is an engineered pressure vessel which is externally mounted to the tank. The float housing is designed to handle the same temperatures andpressures found in the tank. It is fabricated from a variety of materials, depending on the application. The alloy models are usually polyvinyliden fluoride (PVDF). Other materials are available on request.The float (See Figure 3), is equipped witha permanent ring magnet assembly. Thisassembly rides at the surface of the liquidcontained within the float housing, rising and falling as the liquid in the tank rises and falls.As the float moves up and down, a magnetic flux field maintains continuous contact with the rotating flags mounted on theoutside of the float housing. Flag rotation occurs as the fluxFigure 3Standard Alloy Float has a resolution of 1/2” (12.7 mm). Rotating flags have a square profilewith embedded permanent magnets. The flux field generated by the ring magnet in the float interacts with the flag magnets causing them to rotate as the float moves up and down inside the housing. After the flags rotate to the new position, the embedded magnets lock the flags in place, making the flags less sensitive to vibration (See Figures 4 and 5).LevelSite®’s rotating flags are mounted in a housingfabricated of extruded aluminum or polycarbonate. The assembly is attached to the outside of the float housing with stainless steel clamps. The ends are sealed against dust and moisture. Since the flags are never in contact with the liquid, they never need to be cleaned and they can’t discolor. If the rotating flag assembly is accidentally crushed, there is no danger of a liquid spill.The rotating flag assembly is available in aluminum orpolycarbonate and measures 1.18”(30 mm) and 1.02” (26 mm) wide,respectively (See Figure 6).Figure 5Figure 6Level3LevelSite ® Supplemental GuideGeneral SpecificationsAluminum flags are offered in an anodized finish of red andsilver or painted in red and white. Anodized flags are suitable for service up to 400°F (200°C); painted versions can be subjected to 600°F (316°C). A glass pane protects the flags. The housing is extruded, black anodized aluminum.Polycarbonate flag housings are clear and impact-resistant. They offer 180° visibility of the flags; level can be seen from front and sides (See Figure 5). Housing and flags can withstand temperatures to 250°F (121°C). Standard flag colors are red and white.LevelSite®s are designed according to the unique requirements of each application. Based on information provided by the user regarding operating temperature, pressure, and “normal” specific gravity of the liquid, a float is selected appropriate to the application. Maximum and minimum conditions are evaluated to ensure that the LevelSite® will function not only at the normal condition, but at each extreme. Maximum temperature and pressure are parameters used to design the pressure vessel (float housing).9 can be used as a guide in selecting the ANSI class flanges and materialsappropriate for your temperature and pressure conditions.Barksdale’s LevelSite® is a unique system that can be custom designed for many types of applications, from a stand-alone, no-power-required levelindicator to a fully-integrated electroniccomponent within a process controlsystem. It can be supplied with process connections located for any of the four standard patterns: top/bottom, top/side, side/side, or side/bottom (See Figure 7). For applications where tank-side mounting of the LevelSite is not practical or desired, top mounted versions are available. Liquid interface configurations require three process connections (See Figure 7).Quality and dependability are built into every BarksdaleLevelSite. As a registered ISO 9001 manufacturer, Barksdale meets the most demanding international standards. LevelSite® can be certified to ASME, ANSI, DIN, BSP and other codes.System SpecificationsFigure 7ConfigurationQualityMaterialPressure/temperature performance parameters for LevelSite housing constructed of 316 stainless steel are specified in the chart. Please consult the factory with pressures/temperatures requiring other alloys.MaterialPressure/temperature performance parameters for LevelSite housing constructed of PVC, PP or PVDF are specified in the chart.

Make sure that all parts are available and the connecting flanges on the tank correspond to those on theindicator. The float and limit switches (if applicable) are enclosed in a separate box. Remove the bottom connection flange (1) of the float chamber and insert the float with the top uppermost. Replace the bottom flange with the gasket, fixing it to the chamber by tightening all the bolts securely. The LevelSite® must be raised slowly and carefully so that the float is not damaged by severe impact.It is essential to ensure that the flanges on the tank are accurately aligned with the flanges on the LevelSite®. Non-alignment of the flanges causes distortion of the float chamber (2) with the possibility that the float (3) will stick. The Levelsite® must always be mounted vertically. Before commissioning, the flags in the flag assembly (4) must be aligned by means of a magnet so that they all show the color white (polycarbonate) or silver (aluminum). NOTE: It is essential for all flange bolts, the vent-plug (5) and the drain-plug (6) to be fully tightened.The electrical limit switches (7) may be attached at any point in the range on the indicator bar by means of a stainless steel clip. Ensure that the stainless steel clips are installed under the flag assembly. The maximum electrical switching capacity is specified on the nameplate of the limit switch (7) and must not be exceeded. IMPORTANT: The operation of the LevelSite® is based on the magnetic field principle. Ferrous strips, clamps, or screws must not be used.LevelSite®s are always application specific. The most important technical data such as pressure and temperature limits are specified accurately on the nameplate (8). However, the sales drawing for the model number referenced on the nameplate is specific and detailed to the application and is the governingspecification document. Before commissioning, a check must be made to ensure that the technical data shown on the nameplate corresponds exactly with the plant requirements. NOTE: Test pressure and test temperature of the plant must NOT exceed the specifications.The transmitter is installed on the side of the LevelSite® housing, utilizing stainless steel clips, with the transmitter’s probe along the housing. The transmitter may be used in addition to a visual indicator (rotating flag assembly) to provide electronic monitoring of fluid level. If the transmitter is used with a flag assembly, it may be necessary to slide the transmitter’s clamps under the flag assembly. The transmitter is supplied with a mark on its probe. This mark must line-up with the centerline of the processMechanical InstallationElectrical InstallationCommissioningconnector on the LevelSite®. If the transmitter’s probe spans the entire measuring range (center-to-center of the process connections), the probe will be marked to show the measuring range. Electrical Connections: Ground the transmitter’shousing if necessary. The cable length may be up to 3 miles. The transmitter is designed to be maintenance-free and is not field-serviceable. If the unit is not operating properly, replace the entire unit. For more information, refer back to “Tank Level Indicating Transmitter”.Tank Level Indicator (TLI) Installation。

They work on the float principle with magnetic transmission.The float's magnetic system in the guide tube actuates a resistance measuring chain that corresponds to a 3-wire potentiometer circuit. The measurement voltage generated by this is proportional to the fill level.The measurement voltage is very finely-stepped due to the contact separation of the measuring chain and is thus virtually continuous. Depending on the requirements severaldifferent contact separations are available.Level measurementKSR data sheet LM 20.02Page 1 of 18KSR data sheet LM 20.02 ∙ 04/2017Level sensor with reed measuring chainModel FLR, for the process industryfor further approvalssee page 3A division of the WIKA groupModel overviewInternal circuit diagram of the reed sensorsT emperature range (process)■Model FLR-S -80 ... +200 °C ■Model FLR-P -10 ... +100 °C ■Model FLR-H -20 ... +200 °CPage 2 of 18KSR data sheet LM 20.02 ∙ 04/2017Approvals■Model FLR-SKSR data sheet LM 20.02 ∙ 04/2017Page 3 of 18■Model FLR-P■Model FLR-HApprovals and certificates, see websitePage 4 of 18KSR data sheet LM 20.02 ∙ 04/2017Sensor, standard version with connection housing Models FLR-SA, FLR-SBProcess connection, guide tube and float from stainless steelPage 5 of 18KSR data sheet LM 20.02 ∙ 04/2017Sensor, ECTFE coated version with connection housing Models FLR-SA, FLR-SBProcess connection, guide tube material and float from stainless steel 1.4571, ECTFE coatedPage 6 of 18KSR data sheet LM 20.02 ∙ 04/2017Sensor, standard version with cable or plug connection Models FLR-SE, FLR-SFProcess connection, guide tube and float from stainless steelPage 7 of 18KSR data sheet LM 20.02 ∙ 04/2017Sensor, plastic version with connection housing Models FLR-PA, FLR-PBProcess connection, guide tube and float from polypropylene, PVDF or PVCPage 8 of 18KSR data sheet LM 20.02 ∙ 04/2017Sensor, explosion-protected version Ex i, intrinsically safe Models FLR-SAI, FLR-SBI (NMG 125)KEMA 01 ATEX 1052 X (II 1/2G Ex ia IIC T4 ...

(具体说明详见PSG系列电源保护器使用说明书)控制及处理子系统:控制及处理子系统指的是VR 公司具有不同功能的各型控制台。
(具体说明详见产品操作手册)数据采样子系统:数据采样子系统指的是VR公司不同型号的液位探棒。
(具体说明详见产品现场安装准备手册)四、液位仪系统应用的主要功能●计量管理液位仪系统在设置好基本运行参数后(如探杆高度校正值、罐容表等),即可进行昼夜不间断的自动测量。
实时显示各油罐当前油面高度、当前水位高度与前、当前油品温度,还可显示根据罐容表自动计算出的油品存量,方便油站管理人员随时掌握油罐存油量动态。
由于液位测量探杆位置与人工测量孔不同,往往会在液位仪测量值与人工测量值间产生一个固定的高度误差,液位仪可记录此误差值进行高度校正,从而得出与人工测量基本一致的测量数据。
●安全管理液位仪系统在设置好报警参数后(如油位高限值、油位低限值、水位高限值以及溢出报警值等),即可对探杆动态测量数据进行自动监测,当超过设置的报警参数值时,立刻通过液位仪控制台前面板的双色LED灯与蜂鸣器发出声光报警信号,也可触发外部大功率报警装置,从而杜绝进油冒罐事故与水位超高事故的发生。
●库存管理液位仪系统都具有油罐容积表的记录功能,一般需要记录多达128个或更多点的对应容量值才能达到足够的准确度。

WFX-40型自收缆水位计的安装原理图如图1所示,它是单浮子式水位仪传感器。它只有一个直径为Φ100mm(或Φ45mm)浮子,工作于直径Φ(150-100)mm的测压管中,测压管的制作和安装须符合如下条件:
c将测量缆连同浮子投入测压水位管中,沿顺时针方向慢慢转动贮线轮,直至浮子抵达图1所示Hmax水位高度线。此时浮子的行程为H0。
d在浮子大致悬垂于最高水位线高度Hmax时,锁紧固定贮线轮的两个锁紧螺钉,然后慢慢释放贮线轮,使浮子以60cm/min的速度逐渐下沉,直至浮子浮于水面平衡位置时,浮子即会自动停止下沉,此时,浮子工作于图1所示Hx高度的 “工作区”位置。在浮子下沉的过程中,重锤钢缆将逐步缠绕于贮线轮的卷扬轴上,并将重锤提升,当浮子不在下沉时,重锤将会稳定在某一高度上。
井的内壁较光洁,无明显阻滞凸起物,测井井壁的残留凸起物不得阻碍浮子运动;测井的垂直度必须符合要求(倾斜度≤0.5度),或者当浮子沉于井底时,测缆上端不得触碰井口壁。
安装调试步骤如下:
14.1
图1 WFX-D型水位传感器和支承座安装图
按图1的尺寸要求制作传感器支承底座,支承底座之下可用水泥板砌制矩形防护框架,并在仪器过线孔附近留有投放浮子的缺口。支承座距井口上缘的高度为180-200mm,以便于投放浮子,并使测缆垂直穿过支承座的过线孔,对准测井的中心。然后用4个地脚螺钉将仪器底板固定于支承座上。

由于安装调试不慎或其它原因导致测缆从测轮及贮线轮中脱出时,应按如下步骤处理:
a将脱出的测缆轻轻取出,防止测缆弯折;
b按照安装图1所示,正对贮线轮方向,使贮线轮相对静止,用手将测缆按顺时针方向绕于贮线槽中,直至余下约30~50cm长;
c将余下的30~50cm测缆的引出端从悬浮压轮和贮线槽中间穿过,绕经测轮的“V”型凹槽,再从滚动压轮和“V”形凹槽的中间穿出,引向过线轮,然后与浮子悬吊螺钉固定即可。
4·经济性好
传感器加上通信接口、通信电缆的总成本低于其它系统,可靠性及使用寿命(光电传感器的寿命达10万小时)高于其它系统,其综合性能价格比最优。

根据用户的需求,我单位研制了全数字化的WFX-40型自收缆水位计,该系统由WFX型水位传感器、RS485通信接口、测控计算机等组成。
该系统的工作原理是:WFX-40型传感器以直径Φ45mm或Φ100mm的浮子感测水位管的水位变化;力矩自动平衡装置自动释放或提升测缆带动测轮驱动编码器旋转,输出对水位变化对应的全量型格雷码电信号。
图 2
上述步骤完成后,可用手沿顺时针方向转动贮线轮,直至将浮子悬吊螺钉拉至过线孔处为止。然后锁紧贮线轮的两个顶丝。
14.4
用手捏住测量缆,以(40-60)cm/min的速度沿垂直方向拉动测缆运动,使悬吊螺钉进入测井,拉出长度约为2-3米长,边拉边观察测缆是否有阻滞或松脱现象,如无松脱现象即属正常。当牵引测缆运动时,测轮、贮线轮、卷扬轴均会随同旋转,并将重锤提升至一定高度。然后再以(40-60)cm/min的速度慢慢放松测缆,此时~~测轮作顺时针方向旋转、贮线轮作逆时针方向旋转,慢慢将测缆收回贮线轮,直至将悬吊螺钉收回原位,不应有运动阻滞或测缆松脱现象。
16.4
此类故障多为电源线或地线开路或连接插头接触不良所致。此类故障应由专业人员排除。
注意!
检修仪器时,请勿随意打开拆解编码器。如判断为编码器故障,请及时与厂方联系。

电输出接线图
注意:投放浮子时,不可使浮子处于自由落体状态,否则会因浮子下降过快撞击测井或者产生脱缆现象;投放浮子时,如果有阻塞现象,应沿逆时针方向用手慢慢将浮子提出井口,并对井的内壁进行清理,然后,再重新投放浮子。

14.5.3
给传感器及显示器通电,并按照图1所示,松动测轮轴套的锁紧顶丝。然后用手缓慢旋转编码器主轴(顺时针旋转时读数增加,逆时针旋转时读数减少),直至显示器读数与实际水位高度H0的数值相同时为止,然后锁紧测轮的项丝。对水位即告完成。
本类型水位计可选装三种不同的输出方式与计算机联接使用:
(1)并联总线方式:传感器通过14-16芯屏蔽电缆分别与计算机联接;
(2)RS485串行总线联接方式:多个传感器通过一对屏蔽双绞线与计算机联接。
(3)采用模拟量4-20mA信号与计算机联接。

13.1
水位(压力)变幅:0-10m;
浮子直径:Φ10cm;Φ4.5cm;Φ4cm
WFX型水位传感器的输出码为格雷码(一种有纠错功能的格雷码),它可以通过标准译码程序转换成二进制码。传感器的测量缆为Φ0.5mm的包敷尼龙套的不锈钢索,可以在潮湿环境中长期工作。
水位传感器的力矩自动平衡装置是由贮线轮、卷扬轴、重锺、重锺悬吊钢缆、滑轮组等组成。力矩平衡装置的作用是产生一个自动平衡力拉直测量缆,并使浮子工作在正常吃水深度上。当测压管中的水位发生变化,浮子即可通过测量缆将这一微小变力传递给力矩平衡装置并驱动编码器测轮转动,输出与水位变化量相对应的编码数据。
a按照图1所示的要求及测压管埋深和最大水位变幅计算测缆最大长度。绕线轮中的测缆应能满足最低水位的测量要求(订货时,用户须提供测缆长度要求)。
b松动锁紧贮线轮轴套的两个顶丝,并锁紧测轮轴套与编码器转轴的顶丝,使贮线轮可以绕重锤卷扬轴自由旋转,并按图3方法将浮子盖、密封胶垫与浮子连接,并且用手托住浮子,或者用手指捏住贮线轮不使浮子下沉。
14.6
在冬季井口喷出潮湿雾状气体的情况下,为保护仪器,可在传感器底板下面安装防潮气风幕机,风幕机吹出干燥的空气,可以隔离井口喷出的潮气,保护仪器。风幕机为单独直流(或交流)电源供电,不使用仪器蓄电瓶供电。
14.7
按照图1所示,先将仪器机芯用紧固螺钉安装于仪器底座上,再安装仪器上防护罩,即可投入正常使用。
如发现有运动阻滞或测缆松脱现象,应调整悬浮压线轮的位置,使测缆运动时,既无阻滞,又不松脱。
注意:作测缆牵引试验时,勿松开手中的测缆(或浮子盖),导致贮线轮高速旋转,使测缆脱离贮线轮。

安装仪器时,先松开仪器防护罩的紧固螺钉,轻轻取下防护罩。为方便包装运输,在仪器出厂之前,已将仪器的力矩平衡装置的平衡锤(重锤)用螺钉紧固于仪器底板上。做测缆牵引试验之前,应当用螺丝刀从底部将重锤固定螺钉拆除,使重锤能作上升运动。拆除工作完成后,应当用胶带堵上孔洞,以防止潮气从孔洞进入仪器。仪器安装调试完毕应罩上防护罩,并应从安全和防护考虑制作必要的防淋、防盗保护箱。

出现此类现象的原因,多是因为对水位不准或因外界因素使测缆沿测轮的“V”形凹槽滑动所致,也可能因仪器轴承被污导致摩擦阻力加大所致。排除故障方法是,重新对水位,并清洗仪器轴承,并充浠润滑油(缝纫机轴),即可排出故断线、或因雷击导致电子元件损坏所致。此类故障应由专业人员分析排除。

按照传感器输出插座接线图要求,给传感器和显示器通电,用手转动编码器的测轮,并观察显示器显示值,应能连续显示自“0”显示到最大量程的全部编码数据。

用手压住测缆,防止测缆从贮线槽中脱出,然后除去固定测缆用的胶带及软塞,将测缆的引出端按图1所示穿过悬浮压线轮缝隙引向测轮的“V”型凹槽,按逆时针方向绕经测轮V形槽后,垂直向下,再穿过仪器底板过线和安装底板的过线孔,然后与浮子盖相连接。连接方法如图2所示。
