l4660sc超声波液位计说明书
l4660sc超声波液位计说明书L4660SC超声波液位计是一种应用于工业领域的液位测量设备，它采用声波脉冲技术来测量液体的高度。
本说明书将详细介绍L4660SC超声波液位计的特点、工作原理、安装与使用方法以及注意事项。
一、特点：1.高精度：L4660SC超声波液位计采用先进的声波脉冲测量技术，具有高精度和稳定性，可精确测量液体的高度。
2.多功能：本液位计具有多种测量模式，可根据实际需求选择合适的模式，如连续测量模式、点测量模式等。
3.长寿命：采用优质材料和先进工艺制造，具有耐腐蚀、耐高温、抗压强等特点，可在恶劣环境下长期使用。
4.无污染：超声波液位计无需直接接触被测液体，不会对被测介质产生污染，适用于各种液体的测量。
二、工作原理：L4660SC超声波液位计利用声波的传播速度差来测量液体的高度。
当液体介质存在于液位计的测量范围内时，超声波发射器会向下发射一束频率和幅度稳定的声波信号。
声波信号在液体和传感器之间传播，当遇到液体表面时，部分能量被液体吸收，而另一部分能量反射回来。
超声波接收器接收到反射回来的信号，并计算从发射器到液体表面的时间间隔，根据声速和时间间隔的关系，即可计算出液体的高度。
三、安装与使用方法：1.安装：将L4660SC超声波液位计安装在液体容器的顶部，确保传感器与液体表面垂直，在安装过程中需注意避免振动和干扰源等对测量精度的影响。
2.连接：将液位计的输出信号线连接至测量仪表或控制系统，确保连接正确、牢固可靠。
3.参数设置：根据实际需要，通过仪表或控制系统对液位计的参数进行设置，包括单位、测量范围、测量模式等。
4.校准：在使用前，需要对液位计进行校准，确保测量结果的准确性。
具体校准方法可参考本产品的校准说明书。
四、注意事项：1.在安装、使用和维护过程中，请务必参考本说明书，并按照操作规程进行操作。
2.请确保电源的稳定，并遵循相关的电气安全规范。

超声波液位计说明书
技术原理超声波物位计安装于容器上部，在电子单元的控制下，探头向被测物体发射一束超声波脉冲。
声波被物体表面反射，部分反射回波由探头接收并转换为电信号。
从超声波发射到被重新被接收，其时间与探头至被测物体的距离成正比。
电子单元检测该时间，并根据已知的声速计算出被测距离。
通过减法运算就可得出物位值。
技术问答1．超声波物位计适于什么样的应用环境？通常应用于温度在150℃以下、压力在5Bar（5kg/cm2）以下的场所进行液位或料位的测量。
2．对于密闭容器内的挥发性的液体的液位测量，应注意那些事项？应注意两点：a容器内气体声速可能与空气中的声速不同，如液位计不能对声速进行修正，则会出现较大误差；b挥发性的液体会在超声波液位计探头表面凝结，阻挡声波的收发，要求液位计具有可变功率控制功能。
我公司产品能够满足以上要求，并有大量的实践应用。
3．超声波物位计可以测量原煤仓、煤粉仓的料位吗？原煤的料位测量是可行的，有足够的应用经验和成功实例；煤粉仓的料位测量使用超声波方式目前并不理想。
4．对于液面剧烈波动的液体，如何使用超声波液位计进行液位测量？有三种可行的办法：a选用具有自动功率控制功能的超声波液位计b选用更大量程的超声波液位计c在液体中加入塑料管，测量塑料管内液位5．两线制超声波物位计与三线制超声波物位计有和不同？两线制超声波物位计其供电（DC24v）与信号输出（DC4-20mA）共用一个回路，仅使用两条线即可，为标准的变送器形式，不足之处是发射功率微弱，不适合液面有较大波动的液位测量和料位测量，当液体有较大挥发性时，测量效果有时也不理想。
三线制超声波物位计实际上为四线制，其供电（DC24v）与信号输出（DC4-20mA）回路分离，各使用两条线，当它们负端共地相连时，通常使用三条线即可。
其优势是发射功率较大，适合对各种条件的液位和料位进行测量，效果理想。

电脑上物位计调试步骤：一．进入调试软件1. 双击GosHawk软件，弹出GosHawk的工作界面；2. 点击View按键后，选择点击Options，待弹出Properties对话框，然后关闭该对话框；3. 接上步，点击GosHawk工作界面中的Connect按键，待出现Info参数表后，可以点击Diag进入回波动态画面。
4. 点击Setup，从中选择需要设定的菜单目录进行如下二、三、四各步骤的操作（二三四几步的调试同样适用于在仪表上手动调试）。
二．快速设定（即Quick Set）1.设定高物位（即Hi Level）低物位（即Lo Level）注意：高物位要大于盲区值（仪表盲区请参看使用说明书第12页）2.选择测量介质（即Application）；3.设定进料速度（即Fill Rate）出料速度（即Empty Rate），要求是按照最大的进出料速度设定（出厂设定值能够满足许多工矿的应用）。
4.进出料阻尼参数（即Damp Fill与Damp Empty），在设定进出料速度时，软件通过计算，已经将该参数设定好，但可以根据具体情况将该参数增大或减小。
超声波液位计说明书
超声波液位计说明书本说明书适用三线制或4线制、二线制由于盘装式和壁挂式已经停产，使用时可以参考本说明书一，用户自检：A,仪表正确通上合格的电源，按移位键（即左键）找出L（L是探头到反射面的距离），垂直对准空旷的墙面作为超声波的反射面(假设是水面），观察L的数字，显示L的数字和实际距离相等说明测量功能正常. (首先要先熟悉有关距离L和液位H的关系图见附件）.说明:1,由于仪表有严格的数据过滤和确认过程,数字变化可能会比您移动仪表的速度慢一些,属于正常现象。
（有特殊要求请您在订货时说明）2，在检验的过程中应该注意：L（max）≤测量距离能力, L(min）≥仪表的盲区C.3,一般情况下，仪表量程d+盲区C＝仪表最大测量距离能力L（max).4，量程是和输出电流P有关的参数，和其他无关.B，把超声波的发射口对向空旷的天空，一分钟以内仪表应该显示FFFF，也可以取一块干燥的毛巾重叠数层堵住换能器的发射口,从原理上说仪表此时没有回波收到,同样仪表会显示FFFF。
说明您的仪表抗干扰性能不错.C，按移位键找出P（仪表应该输出的电流值）,用电流表直接测量输出电流应该和P值相当.经过以上3个项目的检验,用户可以放心的使用了。
二，连续按移位键可以依次查看仪表的以下参数参数：P—XXXX 当前应该输出的电流（mA）h—XXXX 最后一次所设定的“当前液位"值（m）.h-该参数没有实际意义. 该数对应菜单01C-XXXX 仪表盲区（cm)，盲区固有d—XXXX 仪表量程(m）该数对应菜单02d只和输出电流有关,和其他无关.H当前液（物）位m-XXXX 或L(距离m）XXXX对于三线制超声波液位计用户菜单中编号为07的是工作模式转换。
对于二线制超声波液位计用户菜单中编号为04的是工作模式转换。
工作模式设置为1。
0000时是测量距离模式，设置为0。
000是测量当前液位模式。
按上升键仪器直接显示“当前液位”H 或距离L.按SET键仪器直接显示P.三，如何进入用户菜单：1，先按住上升键(中间键）不放开，然后再按一下SET，显示屏出现-XXXX—密码界面(其中有一位在闪烁).2,交替使用移位键和上升键,使界面改为—1234-(用户密码）,连续按SET键就进入用户设定01….。

容器接管
1.在介质的反射特性好的情况下，容器接管直径较大时，接管长度可略长于换能器（图1）。右边表格 列出对应于不同直径接管的长度推荐值。在这种情况下，接管末端必须平滑，没有毛刺，尽可能将接管 末端磨圆。另外，必须进行“虚假回波学习”。在被测介质反射特性不好，或者料位较高可能连入测量 盲区，因而必须提高接管安装位置时，可选用喇叭型导波管（DB2）安装方式，以增大信号的方向性， 减小接管对测量的影响（图2） 2.容器接管的长度：必须保证探头伸出接管至少10mm

泡沫 气流
由于入料，搅拌或容器内其他过程处理，会在某些液体介质表面形成泡沫，衰弱发射信号。如 果泡沫造成测量误差，应该将传感器安装在导波管内，或使用导波雷达物位计。导波雷达物位 计的测量不受泡沫的影响，是这种应用的最佳选择。 如果容器内有很强的气流，例如：室外安装，而且风很大，或容器内有空气涡流，应该将传感 器安装在导波管内，或使用脉冲雷达物位计或导波雷达物位计
1.2 高位调整
按 键，进入编程低位百分比，参见前述参数编辑方法中的字符/数字参数 编程方法编辑百分比值及距离值。编辑完成后，按 键，确认，按 键放 弃编程。
高位调整用于量程设置。它与低位调整一起决定了电流输出线性对应关系的比 例。当液晶显示菜单号为 1.1 时，按 键进入高位调整，液晶显示
