由于水流指示器种种异常状况的发生使消防工程方经常需要求助厂家上门服务，给厂家增加了本可避免的麻烦及损失，所以为了各方面我们需要在平常中就要提前做好问题的了解，比如水流指示器出现间隙报警和渗漏问题。

Due to the occurrence of various abnormal conditions of the water flow indicator, the fire engineering party often needs to turn to the manufacturer for door-to-door service, which increases the avoidable trouble and loss to the manufacturer. Therefore, in order to understand all aspects, we need to know the problems in advance, such as the gap alarm and leakage of the water flow indicator.

间隙报警

Gap alarm

由于设计和安装的原因，消防管网中有多余的空气，会导致水流指示器产生间歇性间隙报警。严重的管道空气甚可能导致水流指示器反方向动作（没有水的测试会发出很长的报警，但在水测试过程中不会报警）。确认这种情况后，必须采取有效措施排除气体（如增加排气阀等）。在少数工程中，由于设计原因，施工人员无法有效排气，导致水流指示器无法正常工作。

Due to design and installation reasons, there is excess air in the fire pipe network, which will cause intermittent gap alarm of the water flow indicator. Serious pipe air may even cause the water flow indicator to act in the opposite direction (the test without water will send a long alarm, but it will not alarm during the water test). After confirming this situation, effective measures must be taken to remove the gas (such as adding exhaust valve, etc.). In a few projects, due to design reasons, the construction personnel cannot exhaust effectively, resulting in the normal operation of the water flow indicator.

渗漏

leakage

水流指示器漏水，无论是密封膜片漏水还是水流指示器本体由于铸件气孔造成的沙眼漏水，都是生产厂家的产品质量问题。因为厂家在产品出厂前按照GB5135.7标准进行了2.4MPa的密封试验。虽然这种漏水产品的比例很小，但也应该由厂家更换。

Water leakage of the water flow indicator, whether it is the leakage of the sealing diaphragm or the trachoma leakage of the water flow indicator body caused by the air hole of the casting, is the product quality problem of the manufacturer. Because the manufacturer conducted a 2.4Mpa sealing test according to gb5135.7 standard before the product leaves the factory. Although the proportion of this leaking product is very small, it should also be replaced by the manufacturer.

除了以上原因外，报警系统的问题也不容忽视（报警系统包括信号线、电源线、模块、楼层显示器、控制面板等），因为水流指示器本身的原理很简单，动作相当灵敏。只要管道中有水流过，安装在管道上的水流指示器就会立即动作。

In addition to the above reasons, the problems of the alarm system can not be ignored (the alarm system includes signal line, power line, module, floor display, control panel, etc.), because the principle of the water flow indicator itself is very simple and the action is quite sensitive. As long as there is water flowing through the pipe, the water flow indicator installed on the pipe will act immediately.

但是，水流转换的电信号必须通过完整的电气系统进行传输和报警。很多用户抱怨水流量表有问题，但经过现场调查证实，大部分不是水流量表质量问题，而是信号线、电源故障引起的线路、模块故障和控制面板故障。

However, the electrical signal converted by the water flow must be transmitted and alarmed through the complete electrical system. Many users complain that there are problems with the water flow meter, but after field investigation, it is confirmed that most of the problems are not the quality problems of the water flow meter, but the line, module faults and control panel faults caused by signal line and power supply faults.

因此川消厂家提醒用户，当水流指示器产生长报警或不报警时，需要确认报警系统的功能是否良好。造成不必要的麻烦。

Therefore, the manufacturer of Chuanxiao reminds users that when the water flow indicator gives an alarm or does not give an alarm, it is necessary to confirm whether the function of the alarm system is good. Cause unnecessary trouble.
