產(chǎn)品特點(diǎn) products feature

四、產(chǎn)品特點(diǎn) products feature
◆ 采用動(dòng)態(tài)流量補(bǔ)償算法，實(shí)現(xiàn)流量的準(zhǔn)確計(jì)量；
◆ 電子運(yùn)算單元采用美國ti公司msp430系列16位微處理；先進(jìn)的微功耗設(shè)計(jì)；
◆ 完善的，智能化的計(jì)量自診斷和監(jiān)控功能；
◆ 結(jié)構(gòu)緊湊，一體化設(shè)計(jì)結(jié)構(gòu)牢固，抗破壞性好；
◆ 積分儀可上下調(diào)整90°，方便用戶讀數(shù)；
◆ 脈沖輸出和485接口，可實(shí)現(xiàn)數(shù)據(jù)遠(yuǎn)傳、集中控制（可選）；
◆ 電子式多流束無磁流量計(jì)采用電渦流原理采集流量、無鐵屑吸附、保證流量計(jì)的長期使用、特別適合中國供暖水質(zhì)；

◆無磁流量計(jì)采用業(yè)內(nèi)Zui先進(jìn)的線圈式無磁傳感器，內(nèi)部沒有磁鐵，不會(huì)被磁鐵干擾，杜絕了偷熱情況出現(xiàn)，也不會(huì)吸附水中的鐵銹和雜質(zhì)，保證長期使用計(jì)量準(zhǔn)確；
◆采用螺紋導(dǎo)流多流束方式，推動(dòng)葉輪的切向流束均勻，有效克服單流束葉輪一個(gè)方式受力導(dǎo)致單邊的大量磨損，不需要加直管調(diào)整水流，可以水平、垂直傾斜安裝，提高了安裝的靈活性；
◆ 內(nèi)部的唯一磨損部位采用鎢鋼針尖和紅寶石軸承，鎢鋼針尖只能用金剛石鉆頭才能加工出來，保證了產(chǎn)品長期運(yùn)行的準(zhǔn)確性；
◆ 銅件全部采用鍛壓工藝生產(chǎn)，杜絕了翻砂鑄造工藝引起的沙眼匯露現(xiàn)象，每只流量計(jì)均經(jīng)過2.0mpa的壓力實(shí)驗(yàn)，杜絕匯露問題；
◆ 可和本企業(yè)生產(chǎn)的智能熱量控制閥配合，實(shí)現(xiàn)預(yù)付費(fèi)。

◆ use dynamic flow algorithm,can be meter very accurate;
◆ the ic comes form u.s.a. ti company"s msp430 series 16 bitmicro-computer,advance micro function design;
◆ complete make up algorithm,self-check and control fuction;
◆ small strructure,total design structure,anti-broken feature isgood;
◆ the integrating instrument can be nod in 90°,easy to read;
◆ pause export and 485 joggles,can be get the data communicate,andcenter control.(selected);
◆ electric multiple flow meter use the vortex principle and gatherflow,have no iron adsorb,very suite use in china;
◆ no magnet flow meter use the advance coil style sensor,there isno magnet in it,will not be obstruct by magnet,can"t stolen theheat ,and not adsorb iron and jmpurity,protect accurate in longterm;

◆ take the screw drive flow and multiple speed way,push the leafwheel critical flow e ,don"t made the leaf wheel take thepower with only direction and wear,don"t need add the drive pipe toadjust the water direction,can be set in vertical or horizontaldirection,and grow the flexibele to fix;
◆ inner wear parts use the wolfram steel needle and rubiesbearing.the head of wolfram needle only be process by diamond,toprotect the accuracy in a long term;
◆ the brass part be process by forge and press,so has no the sandhole by cast,every meter has passed the check with 2.0mpapressure
◆ can be companied by our factory auto-heat valve,get the prepaidfee。
