一、水表怎么讀?
1、數(shu)字(zi)(zi)水表(biao):水表(biao)怎么看用(yong)了(le)多少水?在數(shu)字(zi)(zi)水表(biao)的(de)最上(shang)方(fang)有5個(ge)(ge)數(shu)字(zi)(zi),其中前四個(ge)(ge)數(shu)字(zi)(zi)是(shi)(shi)(shi)黑色的(de),表(biao)示(shi)的(de)是(shi)(shi)(shi)噸(dun)(dun),第五個(ge)(ge)數(shu)字(zi)(zi)則是(shi)(shi)(shi)紅色的(de),表(biao)示(shi)的(de)是(shi)(shi)(shi)零(ling)點(dian)(dian)幾(ji)(ji)噸(dun)(dun)(0.*噸(dun)(dun))。然后(hou)還(huan)可以看到上(shang)面有三個(ge)(ge)紅色的(de)指(zhi)針(zhen),最上(shang)方(fang)的(de)指(zhi)針(zhen)代表(biao)著是(shi)(shi)(shi)用(yong)水零(ling)點(dian)(dian)零(ling)幾(ji)(ji)噸(dun)(dun)(0.0*噸(dun)(dun)),中間的(de)指(zhi)針(zhen)表(biao)示(shi)的(de)是(shi)(shi)(shi)零(ling)點(dian)(dian)零(ling)零(ling)幾(ji)(ji)噸(dun)(dun)(0.00*噸(dun)(dun)),最后(hou)則表(biao)示(shi)的(de)是(shi)(shi)(shi)零(ling)點(dian)(dian)零(ling)零(ling)零(ling)幾(ji)(ji)噸(dun)(dun)(0.000*噸(dun)(dun))。
2、指針水表:指針水表是非常老式的一種水表品牌產品,采取的是十進位(wei)(wei)(wei)累進計數(shu)(shu)的方式,黑盤(pan)指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)數(shu)(shu)有(you)個、十、百、千(qian)四個指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)盤(pan),查表時要掌(zhang)握(wo)進位(wei)(wei)(wei)方法,個位(wei)(wei)(wei)指(zhi)(zhi)(zhi)(zhi)(zhi)針沒(mei)走到(dao)0,十位(wei)(wei)(wei)表指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)數(shu)(shu)不(bu)得進位(wei)(wei)(wei);十位(wei)(wei)(wei)指(zhi)(zhi)(zhi)(zhi)(zhi)針沒(mei)走到(dao)0,百位(wei)(wei)(wei)表指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)數(shu)(shu)不(bu)得進位(wei)(wei)(wei);百位(wei)(wei)(wei)指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)針沒(mei)走到(dao)0,千(qian)位(wei)(wei)(wei)表指(zhi)(zhi)(zhi)(zhi)(zhi)示(shi)數(shu)(shu)不(bu)得進位(wei)(wei)(wei)。
3、智能(neng)水(shui)表(biao):這種(zhong)水(shui)表(biao)是近幾年來新興(xing)的水(shui)表(biao),采用的是IC卡智能(neng)水(shui)表(biao),它的盤與數字水(shui)表(biao)基(ji)本上都是一致的,看(kan)法也與數字水(shui)表(biao)相(xiang)差無幾,大(da)家在看(kan)的時候就(jiu)采取數字水(shui)表(biao)的方(fang)式即可。
4、跳(tiao)字(zi)式水(shui)表:跳(tiao)字(zi)式水(shui)表只(zhi)(zhi)讀(du)(du)取四位黑(hei)字(zi)的(de)有效數(shu)(shu)值,其他指(zhi)針只(zhi)(zhi)作(zuo)為水(shui)表檢(jian)驗時使用(yong)的(de),用(yong)戶不(bu)必(bi)讀(du)(du)取。跳(tiao)字(zi)式水(shui)表的(de)每個小(xiao)表上(shang)面有單位的(de),你只(zhi)(zhi)需要(yao)把表上(shang)的(de)數(shu)(shu)讀(du)(du)出來乘以(yi)單位,最后全部(bu)相(xiang)加就(jiu)是(shi)了總數(shu)(shu),用(yong)這個數(shu)(shu)減去你上(shang)個月(yue)讀(du)(du)出來的(de)數(shu)(shu),就(jiu)是(shi)你這個月(yue)用(yong)的(de)。
二、水表不用水為什么還轉
出現這種情況的(de)(de)原(yuan)因并不復(fu)雜,當(dang)新安裝水(shui)(shui)(shui)(shui)(shui)表或水(shui)(shui)(shui)(shui)(shui)表外移時(shi)(shi),管(guan)(guan)道內(nei)(nei)的(de)(de)水(shui)(shui)(shui)(shui)(shui)被(bei)放空(kong),空(kong)氣(qi)(qi)(qi)便“乘虛(xu)而入”;當(dang)恢復(fu)通水(shui)(shui)(shui)(shui)(shui)時(shi)(shi),水(shui)(shui)(shui)(shui)(shui)流把(ba)管(guan)(guan)道內(nei)(nei)的(de)(de)空(kong)氣(qi)(qi)(qi)壓(ya)(ya)向室內(nei)(nei)管(guan)(guan)道各個(ge)盲端,形(xing)成“壓(ya)(ya)縮空(kong)氣(qi)(qi)(qi)”,直(zhi)到(dao)氣(qi)(qi)(qi)壓(ya)(ya)與水(shui)(shui)(shui)(shui)(shui)壓(ya)(ya)平衡(heng)為止(zhi)。氣(qi)(qi)(qi)、水(shui)(shui)(shui)(shui)(shui)之間(jian)存(cun)在一個(ge)界面,此(ci)時(shi)(shi)界面兩(liang)邊的(de)(de)壓(ya)(ya)差為零;而當(dang)水(shui)(shui)(shui)(shui)(shui)壓(ya)(ya)發生變化時(shi)(shi),界面兩(liang)邊就(jiu)形(xing)成了一定(ding)的(de)(de)壓(ya)(ya)差,氣(qi)(qi)(qi)、水(shui)(shui)(shui)(shui)(shui)平衡(heng)被(bei)破壞。要彌補(bu)這個(ge)壓(ya)(ya)差,達到(dao)新的(de)(de)平衡(heng),必須相應改變空(kong)氣(qi)(qi)(qi)的(de)(de)壓(ya)(ya)力(li),從而引起空(kong)氣(qi)(qi)(qi)體積膨脹或收縮,由(you)此(ci)促使管(guan)(guan)道這個(ge)“連(lian)通器”內(nei)(nei)的(de)(de)自來(lai)水(shui)(shui)(shui)(shui)(shui)產生流動(dong),于是(shi),“水(shui)(shui)(shui)(shui)(shui)表空(kong)轉(zhuan)”現象(xiang)就(jiu)產生了。
