水流指示器是用来观测管道内介质实时动态和向管道控制中心输送管道动态的一种指示器。正常情况下安装在管道系统的横向水管上，在消防管道系统中应用广，是管道系统是重要组成部件。下面川消小编为您讲解下：水流指示器特点和使用注意事项。

The water flow indicator is an indicator used to observe the real-time dynamics of the medium in the pipeline and the dynamics of the transmission pipeline to the pipeline control center. It is normally installed on the horizontal water pipe of the pipeline system and widely used in the fire protection pipeline system. It is an important component of the pipeline system. The following is Sichuan Xiaobian's explanation of the characteristics and precautions of the water flow indicator.

水流指示器特点：

Characteristics of water flow indicator:

结构合理，水流指示器结构组合简单，占用空间小，重量轻盈，运输携带方便，安装时占用的空间很小，几乎不会占用其它管道系统的正常使用空间。

Reasonable structure, simple structure combination of water flow indicator, small space occupation, light weight, convenient transportation, small space occupation during installation, hardly occupying the normal use space of other pipeline systems.

性能好，工作稳定，即使在管道温度冷热变化的时候，也能准确的反应当前管道介质的动态，有很高的精准度，工作性能非常好。

Good performance and stable operation. It can accurately reflect the current pipeline medium dynamics even when the pipeline temperature changes from cold to hot, with high accuracy and excellent performance.

应用广，除了在石油化工、医疗卫生、食品制造、水电工业和能源工业中被广泛的用来计算各种介质流速之外，水流指示器也常被使用在消防管道中，在产生火情时为消防系统发送消防警报。

It is widely used. In addition to being widely used to calculate the flow rate of various media in petrochemical, medical and health, food manufacturing, hydropower and energy industries, the water flow indicator is also often used in fire pipelines to send fire alarm to the fire protection system in case of fire.

水流指示器使用注意事项：

Precautions for use of water flow indicator:

水流指示器的正确安装方法是安装管道系统的水平或者横向管道上，为了不影响水流指示器的性能，不使用侧装或者倒装水流指示器。应该根据实际使用管道的直径等参数来选择水流指示器的型号，为保证工作效率，一般情况下建议水流指示器的口径不低于安装管道口径的5倍。根据不同的使用环境和使用目的，对水流指示器进行延迟时间的调整，以便达到优良的使用效果。

The correct installation method of the water flow indicator is to install it on the horizontal or horizontal pipeline of the pipeline system. In order not to affect the performance of the water flow indicator, it is not recommended to use the side-mounted or inverted water flow indicator. The model of the water flow indicator should be selected according to the actual diameter of the pipeline and other parameters. In order to ensure the working efficiency, it is generally recommended that the diameter of the water flow indicator should not be less than 5 times the diameter of the installed pipeline. Adjust the delay time of the water flow indicator according to the different use environment and purpose, so as to achieve good use effect.

目前市场上水流指示器有叶轮式和浮球式两种大类，根据不同的连接方式又有螺纹式、法兰式、焊接式等型号，相信这么多型号会让您在选购水流指示器眼花缭乱，我们http://www.cx-fire.com根据客户的实际使用情况为客户适用的阀门！

At present, there are two types of water flow indicators on the market: impeller type and floating ball type. According to different connection modes, there are threaded type, flange type, welding type and other models. I believe that so many models will dazzle you when you buy water flow indicators. We http://www.cx-fire.com Recommend applicable valves for customers according to their actual use!
