測量原理

超聲波液位計的原理是测量一个超声波脉冲从发出到返回整个过程所需的时间。超聲波液位計垂直安装在液体的表面，它向液面发出一个超声波脉冲，经过一段时间，超聲波液位計的传感器接收到从液面反射回的信号，信号经过变送器电路的选择和处理，根据超聲波液位計发出和接收超声波的时间差，计算出液面到传感器的距离。

超聲波液位計的技术优势：超聲波液位計是非接触测量方式，±0.2%精度，1-25米量程，优异的聚焦：5度声束角，多种传感器材质，内置全量程溫度补偿。超聲波液位計测量有腐蚀（酸、碱）的介质、有污染的场合（下水道），或易产生粘附物的物质。适合于那些无法用物理方式接触的液体。

超聲波液位計的組成部分：超聲波換能器、處理單元、輸出單元。

德克森仪表专业提供进口超聲波液位計，长期备有大量现货，性能稳定，质量可靠，并提供各种售后服务。

應用指南

超聲波液位計 针对腐蚀性、有结层或者是含酸碱废水来说，都是一种非常理想的测量工具。超聲波液位計可测量的介质包括盐酸、硫酸、氢氧化物、废水、树脂、石蜡、泥浆、碱液和漂白剂等工业用剂，广泛应用于水处理、化工、电力、冶金、石油、半导体等行业。

超聲波液位計的優點

非接觸式測量
無可動部件、結構簡單、使用壽命長
耐腐蝕（探頭大多采用PVDF、PP等材料）
自动溫度补偿功能
不受介質濕度、粘度的影響
不受介質介電常數、電導率、熱導率的影響
優異的性能價格比

超聲波液位計的注意事項

耐溫能力有限，大多數小于60℃，個別特殊産品可達100℃
真空环境下无法测量，壓力的大幅波动影响测量精度
安裝時盡量避開氣泡、障礙物、波浪等幹擾因素

"Oh!--good-bye, just anybody?" I asked; and thereupon she gathered up all her misplaced trust in me, all her maiden ignorance of what is in man, and all her sweet daring, to murmur-- "I am sorry I spoke harshly to you just now," she said. "Drink this. It is my own pet mixture of sal volatile and a spirit of my own. It will act like a charm on those frayed nerves of yours." Another condition of apprenticeship that is equally as difficult to define as the commercial value of mechanical knowledge, or that of apprentice labour, is the extent and nature of the facilities that different establishments afford for learners. The quality of castings is governed by a great many things besides what have been named, such as the manner of gating or flowing the metal into the moulds, the temperature and quality of the iron, the temperature and character of the mould—things which any skilled foundryman will take pleasure in explaining in answer to courteous and proper questions. In respect to the difference between expanding and solid dies it consists mainly in the time required to run back, and the injury to dies which this operation occasions. Uniformity of [145] size is within certain limits insured by solid dies, but they are more liable to derangement and less easy to repair than expanding or independent dies. CHAPTER IV The physics of Stoicism was, in truth, the scaffolding rather than the foundation of its ethical superstructure. The real foundation was the necessity of social existence, formulated under the influence of a logical exclusiveness first introduced by Parmenides, and inherited from his teaching by every system of philosophy in turn. Yet there is no doubt that Stoic morality was considerably strengthened and steadied by the support it found in conceptions derived from a different order of speculations; so much so that at last it grew to conscious independence of that support. He spends his entire time between classes in trying to figure What seems to you the right thing for me to do? “Atley,” she told the millionaire, “we are getting nowhere. For my part I believe that the emeralds have already been destroyed!” Landor interrupted by taking the slipper from Felipa's foot and killing with it a centipede that crawled up the wall of the abode. "That's the second," he said, as he put the shoe on again. "I killed one yesterday; the third will come to-morrow." Then he went back to his chair and to the discussion, and before long he was called to the adjutant's office. "Such as—" John Gay, a contemporary of Pope, Swift, and Arbuthnot, is now best known by his "Fables" and his "Beggar's Opera." His "Fables" have been extremely popular, and still make him a general name; but, in his own time, his "Beggar's Opera" was his great success. Its wit, its charming music, its popular characters, gave it a universal favour; and it is the only English opera that even to this time has become permanent. Gay's "Trivia; or, the Art of Walking the Streets of London," is still amusing, and some of his ballads have a lightness and buoyancy about them which justify the esteem in which he was held. "Here, Sergeant," called out the Provost-Marshal from the other room, "what are you fooling around in there so long for?" "No, it ain't Grant, neither," said Gid Mackall. "Too big. Must be Gen. Thomas." "Oh, and her liddle dentical ways!" "Not so, my lord," said Isabella, at the moment entering the hall, attracted by the loud tones of De Boteler's voice; "not so, my lord; the tumbrel is not for such as he, however rude his bearing. My Lord de Boteler," turning to the monk, "has doubtless given you an answer—retire, and do not farther provoke his wrath." The lord mayor approached the table at which Richard had seated himself, and presenting a box of dice, challenged the young monarch to play. At the same instant, one esquire placed on the table a bowl of gold, another a box containing jewels, and a third a golden cup, as pledges for the civic gambler. Richard accepted the challenge, and of course was permitted to win; and father John, who stood among the group looking on, seized the favourable moment of royal exultation to prefer his suit. He stepped forward, and kneeling before the young king, to the surprise of all, and to the particular annoyance of the ostentatious citizens, exclaimed— HoME 草榴区t66yENTER NUMBET 0019siz7ty.com.cn
