| 四、北京益都立式多流冷热量表产品特点 Products Feature
◆ 采用动态流量补偿算法，实现流量的精确计量；
◆ 电子运算单元采用美国TI公司MSP430系列16位微处理；先进的微功耗设计；
◆ 完善的，智能化的计量自诊断和监控功能；
◆ 结构紧凑，一体化设计结构牢固，抗破坏性好；
◆ 积分仪可上下调整90°，方便用户读数；
◆ 脉冲输出和485接口，可实现数据远传、集中控制（可选）；
◆ 电子式多流束无磁流量计采用电涡流原理采集流量、无铁屑吸附、保证流量计的长期使用、特别适合中国供暖水质；
◆ 无磁流量计采用业内最先进的线圈式无磁传感器，内部没有磁铁，不会被磁铁干扰，杜绝了偷热情况出现，也不会吸附水中的铁锈和杂质，保证长期使用计量准确；
◆ 采用螺纹导流多流束方式，推动叶轮的切向流束均匀，有效克服单流束叶轮一个方式受力导致单边的大量磨损，不需要加直管调整水流，可以水平、垂直倾斜安装，提高了安装的灵活性；
◆ 内部的唯一磨损部位采用钨钢针尖和红宝石轴承，钨钢针尖只能用金刚石钻头才能加工出来，保证了产品长期运行的准确性；
◆ 铜件全部采用锻压工艺生产，杜绝了翻砂铸造工艺引起的沙眼汇露现象，每只流量计均经过2.0MPa的压力实验，杜绝汇露问题；
◆ 可和本企业生产的智能热量控制阀配合，实现预付费。
◆ Use dynamic flow algorithm,can be meter very accurate;
◆ The IC comes form U.S.A. TI company\'s MSP430 series 16 bit micro-computer,advance micro function design;
◆ Complete make up algorithm,self-check and control fuction;
◆ Small strructure,total design structure,anti-broken feature is good;
◆ The integrating instrument can be nod in 90°,easy to read;
◆ Pause export and 485 joggles,can be get the data communicate,and center control.(selected);
◆ Electric multiple flow meter use the vortex principle and gather flow,have no iron adsorb,very suite use in China;
◆ No magnet flow meter use the advance coil style sensor,there is no magnet in it,will not be obstruct by magnet,can\'t stolen the heat ,and not adsorb iron and jmpurity,protect accurate in long term;
◆ Take the screw drive flow and multiple speed way,push the leaf wheel critical flow equality ,don\'t made the leaf wheel take the power with only direction and wear,don\'t need add the drive pipe to adjust the water direction,can be set in vertical or horizontal direction,and grow the flexibele to fix;
◆ Inner wear parts use the wolfram steel needle and rubies bearing.The head of wolfram needle only be process by diamond,to protect the accuracy in a long term;
◆ The brass part be process by forge and press,so has no the sand hole by cast,every meter has passed the check with 2.0MPa pressure
◆ Can be companied by our factory auto-heat valve,get the prepaid fee。 |
