2 years 分流旋翼式蒸汽流量计 分流旋翼式蒸汽流量计是计量流经管道内饱和蒸汽或微过热蒸汽流量的质 量流量计,能在现场或远传显示蒸汽质量流量的累计或瞬时值、分机械型、智能 型.智能型可温、压补偿,测量过热蒸汽.流量计配有 l 、

2 、

3 号节流孔 板,可通过更换节流孔板改变流量范围.本流量计的测量范围广、精确度高、寿 命长、操作、维修方便,广泛用于石油、化工、轻工等工业部门的蒸汽流量计量. Triage triage rotor steam flowmeter flowmeter rotor steam download instructions Rotor streaming steam flowmeter measurement of flow through tubes are saturated or slightly superheated steam steam flow mass flowmeter can be at the scene or FarEasTone shows the cumulative mass flow of steam or the instantaneous value, sub-machine-type, intelligent type. Smart can be temperature, pressure compensation, measuring superheated steam. Flowmeter with l, 2,

3 No. plate cutting, plate cutting through the replacement of the scope of change in flow. Flowmeter measurement of the wide range of high precision, long life, operation, maintenance convenience, are widely used in petroleum, chemical, light industry, such as the industrial sector of steam flow measurement.

二、流量计的正确选型 流量计的口径及孔板号的选型很重要, 要遵循一些原则进行选择;

应根据被 测蒸汽的最大流量、常用流量、最高压力;

流量测量范围应处于仪表的最佳工作 范围(即公称注流量的

50 % -100 % )见表

1 , 来选定流量计的口径及孔板号. Second, the correct selection of flowmeters Flowmeter orifice diameter and its selection is very important to follow some principles of selection;

should be based on the measured maximum steam flow, commonly used traffic, the maximum pressure;

flow measurement should be the best instrument in the scope of work (that is, nominal Note flow of 50% -100%) in Table 1, to selected orifice flowmeter and No. caliber.

三、结构及工作原理 流量计主要由节流体,阻尼器和指示器三大部件组成,是一种差压一分流原 理式仪表,被测介质蒸汽进人流量计节流体后,一部分通过主管道节流孔板,一 部分经分流管流经喷嘴,射流到叶轮上,对叶轮形成转矩,使叶轮带动转子轴旋 转,在转子轴的下部装有阻尼叶片,安装在注满阻尼液的阻尼室中,使叶轮转动 受到制约,所以它的转速比蒸汽的喷速慢得多,因此,叶轮能有效地吸收蒸汽喷 速的功能,使它的旋转速度与蒸汽喷射造成的转矩及阻尼力矩相对应,并形成一 确定量的关系,叶轮转速与流量成正比. 智能型流量计是采用耐高温传感器、 叶轮直接带动传感器,无需齿轮减速,可温度补偿密度,液晶就地显示也可远传 二次仪表. 南京迪泰尔仪表机电设备有限公司 http://www.迪泰尔.cn/ 地址 : 大光路

Smart flowmeter temperature sensors are used, directly Driven Impeller sensors, no need to gear reducer can be temperature and pressure compensated density, liquid crystal display can also be in situ FarEasTone Secondary Instrument.
