进口金属管浮子流量计 产品用途 Product use

1.主要有三大部分组成：1.测量管体；2.锥形浮子；3.指示器，它可用来测量液体、气体以及蒸汽的流量，特别适宜低流速小流量的介质流量测量 It mainly consists of three parts: 1. Measuring tube body; 2. Conical float; 3. Indicator, which can be used to measure the flow of liquid, gas, and steam, especially suitable for medium flow measurement with low flow rate and small flow rate

2.浮子的位移量与流量大小成正比，通过磁耦合系统，以不接触方式，将浮子位移量传给指示器指出流量大小 The displacement of the float is proportional to the flow rate. Through a magnetic coupling system, the float displacement is transmitted to the indicator in a non-contact manner to indicate the flow rate

3.也可配合不同的转换器，将流量值转换成标准的电远传信号如4-20mA It can also be combined with different converters to convert the flow value into a standard electrical remote transmission signal such as 4-20mA

4.实现距离远传显示、记录、积算和控制等功能 Achieve functions such as distance remote display, recording, integration, and control

5.具有特别的双指示系统，双行液晶数字显示，耐高温高压 With a unique dual indicator system, dual line LCD digital display, high temperature and high pressure resistance

安装示意图

1.安装操作之前，应拆卸所有包装，取出运输中固定浮子的部件，并检查有无损坏 

2.安装到工艺管道之前，将管道里的焊渣清洗干净，防止管道中杂质堵塞仪表，影响正常使用。

3.为了保证测量精度，推荐在流量计上游安装5DN的入口直管段，下游安装250mm出口直管段。

4.流量计有垂直安装和水平安装形式，如果是垂直安装形式安装垂直度应该保证优于1%，如果是水平安装形式，安装垂直度和水平度都应该保证优于1%。

5.若介质中含有固体杂质，应在阀门和直管段间加装过滤器；若介质中含有铁磁物质，应在流量计上游安装磁过滤器。

6.由于金属管浮子流量计安装一个磁远传系统，要确保周围其他设备产生的磁场不影响测量结果。

7.安装在管道中的仪表不应受到压力的作用，仪表的出入口应有合适的管道支撑，使仪表处于最小的应力状态。

8.低温介质测量时，需选夹套型。
