熱量表中的溫度傳感器和流量傳感器的作用及組合：

溫度傳感器和流量傳感器是熱量表中*的器件，熱量表中的積算儀便是通過搜集這兩個(gè)傳感器的信號(hào)來核算熱交換系統(tǒng)所獲得的熱量。
 

    熱量表中的溫度傳感器是搜集水的溫度并宣告溫度信號(hào)的部件，常用的溫度傳感器是由鉑電阻組成，它的特性是溫度越高阻值越大，電阻的大小可以通過導(dǎo)線傳到很遠(yuǎn)的當(dāng)?shù)厝y量，根據(jù)鉑電阻的改動(dòng)我們就可以得到溫度的改動(dòng)。當(dāng)然溫度傳感器并不是這一種，也可以選用其它種的傳感器。
 

    熱量表中的流量傳感器是搜集水的流量并宣告流量信號(hào)的部件，常用的有孔板差壓式、旋渦式、渦輪式等。渦輪式流量傳感器是一個(gè)小水輪發(fā)電機(jī)，和水力發(fā)電用的水輪發(fā)電機(jī)是一個(gè)道理。只不過非常細(xì)巧而簡略，僅僅是由管道里的一個(gè)葉輪和管外的線圈所構(gòu)成。葉輪上有一小塊磁鐵，當(dāng)葉輪被水激動(dòng)而旋轉(zhuǎn)時(shí)，線圈切開磁力線就會(huì)宣告交流信號(hào)來。管道里的水流量越大，當(dāng)然葉輪轉(zhuǎn)得越快，宣告的交流頻率就越高。用頻率來代表流量，這樣就簡略傳到別處去了，所以這才稱得上是傳感器。
 

    通過這些傳感器測量的數(shù)據(jù)加上微處理機(jī)的算法就可以核算到每月的供暖費(fèi)用是多少，這些數(shù)據(jù)還能跟銀行聯(lián)網(wǎng)，省去現(xiàn)金繳費(fèi)的費(fèi)事。

熱量表流量傳感器和溫度傳感器安裝方法

    1.一次計(jì)量系統(tǒng)：這種安裝情況指在整個(gè)供暖系統(tǒng)中，只有這一個(gè)計(jì)量系統(tǒng)。 

    2.二次計(jì)量系統(tǒng)：和一次系統(tǒng)不同的是安裝位置處的計(jì)量屬于第二次計(jì)量。 

    3.家庭用戶中的單獨(dú)供暖計(jì)量：隨著分戶計(jì)量的普及和供暖節(jié)能工程的推進(jìn)目前這種安裝方法比較常見。 

    4.垂直供暖的分配計(jì)量：主要用于垂直供暖系統(tǒng)中的供暖計(jì)量。
