質量流量計

科里奥利質量流量計（Coriolis Mass Flowmeter）简称科氏力流量计，是一种利用流体在振动管道中流动时产生与质量流量成正比的科里奥利力原理来直接测量质量流量的装置，由流量检测元件和转换器组成。科里奥利質量流量計实现了质量流量的直接测量，具有高精度，可测多重介质和多个工艺参数的特点，广泛应用于石化，制藥，食品等行业。流體爲了反抗這種強迫振動，會給管子一個與其流動方向垂直的反作用力，在這種被叫做科裏奧利效應力的作用下，管子的震動不同步了，入口段管與出口段管在振動的時間先後商會出現差異，（差異是由于入口段和出口段流體流向是相反的），這叫做相位時間差。

産品簡介 / Introduction

流體爲了反抗這種強迫振動，會給管子一個與其流動方向垂直的反作用力，在這種被叫做科裏奧利效應力的作用下，管子的震動不同步了，入口段管與出口段管在振動的時間先後商會出現差異，（差異是由于入口段和出口段流體流向是相反的），這叫做相位時間差。

这种差异与流过管子的流体质量流量的大小成正比。如果通过电路能检测出这种时间差异的大小，则就能将质量流量的大小给确定了。这种流量计被称作科里奥利直接質量流量計，它与世界上目前在用的几十种常规容积式流量计的不同是它测的质量的大小，使用的单位是kg/h。用质量（如千克）作单位的流量计比用容积（如立升或立方米）作单位的容积式流量计要准确和恒定。因为质量是遵循守恒定律的。

産品優點 / Product advantages

1、直接測量管道內流體的質量流量以及流體密度；

安裝注意事項 / Installation precautions

1、流量传感器应安裝在一个坚固的基础上。内径小于10mm的小口徑質量流量計安裝在平衡坚硬和无振动的底面上，如墙面、地面或专门的基础。如果在高振动环境使用，应注意对基础的振动吸收，而且传感器进出口与管道之间应用柔性管道连接；较大口徑的流量计直接安裝在工艺管道上，应用管卡和支撑物将流量计牢牢地固定；
2、盡爲防止CMF間的相互影響，在多台流量計串聯或並聯使用時，各流量傳感器之間的距離應足夠遠，管卡和支撐物應分別設置在各自獨立基礎上；
3、爲保證使用時流量傳感器內不會存積氣體或液體殘值，對于彎管型流量計，測量液體，彎管應朝下，測量氣體時，彎管應朝上。測量漿液或排放液時，應將傳感器安裝在垂直管道，流向由下而上。對于直管型流量計，水平安裝時應避免安裝在最高點上，以免氣團存積。連接傳感器和工藝管道時，一定要做到無應力安裝，特別對某些直管型測量管的流量傳感器更應注意。

‘Are you going home?’ asked the other. ‘My wife, I know, is calling on Lady Keeling, and she will pick me up there. If she has not been so fortunate as to find Lady Keeling in, she will wait for me in the motor. May we not walk down there together?’ ‘My dear,’ he said, ‘I am so glad you have let me come to you. You are in deep waters, poor girl.’ I saw two. "Yes," he said, dismounting and motioning me to do the same. Kendall took our bridles. Leaving him with the animals we went over the fence, through the cotton, across the road at a point terribly near the lighted and guarded shop, and on down the field of corn, to and over its farthest fence; stooping, gliding, halting, crouching, in the cotton-rows and corn-rows; taking every posture two upright gentlemen would rather not take; while nevertheless I swelled with pride, to be alone at the side--or even at the heels--of one who, for all this apparent skulking and grovelling, and in despite of all the hidden drawings of his passion for a fair woman at this hour somewhere in peril, kept his straight course in lion-hearted pursuit of his duty (as he saw it) to a whole world of loves and lovers, martyrs and fighters, hosts of whom had as good a right to their heart's desire as I to mine or he to his; and I remembered Charlotte Oliver saying, on her knees, "I believe no beauty and no joy can be perfect apart from a love that loves the whole world's joy better than any separate joy of any separate soul." That Plato put forward the ethical theory of the Protagoras in perfect good faith cannot, we think, be doubted; although in other writings he has repudiated hedonism with contemptuous aversion; and it seems equally evident that this was his earliest contribution to positive thought. Of all his theories it is the simplest and most Socratic; for Socrates, in endeavouring to reclaim the foolish or vicious, often spoke as if self-interest was the paramount principle of human nature; although, had his assumption been formulated as an abstract proposition, he too might have shrunk from it with something of the uneasiness attributed to Protagoras. And from internal evidence of another description we have reason to think that the Dialogue in question is a comparatively juvenile production, remembering always that the period of youth was much more189 protracted among the Greeks than among ourselves. One almost seems to recognise the hand of a boy just out of college, who delights in drawing caricatures of his teachers; and who, while he looks down on classical scholarship in comparison with more living and practical topics, is not sorry to show that he can discuss a difficult passage from Simonides better than the professors themselves. Nor is this all. After sharply distinguishing what is from what is not, and refusing to admit any intermediary between them, Aristotle proceeds to discover such an intermediary in the shape of what he calls Accidental Predication.236 An accident is an attribute not necessarily or usually inhering in its subject—in other words, a co-existence not dependent on causation. Aristotle could never distinguish between the two notions of cause and kind, nor yet between interferences with the action of some particular cause and exceptions to the law of causation in general; and so he could not frame an intelligible theory of chance. Some propositions, he tells us, are necessarily true, others are only generally true; and it is the exceptions to the latter which constitute accident; as, for instance, when a cold day happens to come in the middle341 of summer. So also a man is necessarily an animal, but only exceptionally white. Such distinctions are not uninteresting, for they prove with what difficulties the idea of invariable sequence had to contend before even the highest intellects could grasp it. There was a constant liability to confound the order of succession with the order of co-existence, the order of our sensations with the order of objective existence, and the subjection of human actions to any fixed order, with the impossibility of deliberation and choice. The earlier Greek thinkers had proclaimed that all things existed by necessity; but with their purely geometrical or historical point of view, they entirely ignored the more complex questions raised by theories about classification, logical attribution, and moral responsibility. And the modifications introduced by Epicurus, into the old physics, show us how unanswerable Aristotle’s reasonings seemed to some of his ablest successors. only three dances with me. He said he was bashful about dancing Please get well--fast--fast--fast. I want to have you close So it was in Larry’s race, with Dick, Sandy and the caretaker. "I'm goin' to stop him killin' mules," he said to himself. "I rayly hope I won't kill him, but that's a secondary matter. Providence'll settle that. It's my duty to stop him. That's clear. If his time's come Providence'll put the bullet where it'll kill him. If it ain't, it won't. That's all. Providence indicates my duty to me. The responsibility for the rest is with Providence, who doeth all things well." ile look 4 it EvEry dAy til i git it. Awake, oh, for shame, ye electors of Rye! He had flung off his coat, and squared up to Realf, who, seeing no alternative, began to strip. "My lord," said Richard, "we are resolved to meet these bold men, and hear what they have to say. Shall you attend us, my lord of Canterbury?" HoME sewangdaquan ENTER NUMBET 0010aab66.com.cn
