Things to note when using a float meter for the first time
2011-9-22 10:00:15

     

         流量计仪表 属于精密设备,所以在运输、安装、储存和使用过程中,必须要轻拿轻放, 避免过力安装;同时 还要 保证指示器和传感器 相对位置不能改变, 如果 相对位置发生改变,会直接影响浮子流量计仪表的测量精度; Since the flow meter is a precision device, it must be handled gently during transportation, installation, storage, and use to avoid excessive force installation. At the same time , the relative position of the indicator and sensor cannot be changed. The change will directly affect the measurement accuracy of the float meter ; 管道中要有铁磁性物质吸附在浮子上 In use, ferromagnetic substances must be adsorbed on the float in the inevitable pipeline . 的话 ,会将浮子卡死或 影响测量精度,所以要定期对仪表的测量管进行清洗。 If there are too many impurities , the float will be stuck or the measurement accuracy will be affected, so the measuring tube of the instrument should be cleaned regularly. 在仪表的入口装有磁过滤器, 同时还要 对磁过滤器定期清洗; When necessary , a magnetic filter is installed at the entrance of the meter, and the magnetic filter is regularly cleaned; 仪表的指示器内装有电子器件,所以仪表在拆装外壳和使用 过程中,要将盖的螺钉旋紧,保持壳体密封, 还必须 要防止液体、铁磁性物质和腐蚀性气体等有害物质进入对仪表 产生影响 ,同时要保证仪表的外壳可靠接地; Because the indicator of the instrument contains electronic components, during the disassembly and assembly of the instrument and the use of the instrument , the screws of the cover must be tightened to keep the case sealed, and liquids, ferromagnetic substances and corrosive gases must be prevented. The entry of material has an impact on the meter , and at the same time, the shell of the meter must be reliably grounded;

 

以下几点 Pay attention to the following points when using the flow meter for the first time :

1   过程中,为 避免突然打开阀门,形成水头冲击, 导致 仪表损坏, 一定 要缓慢地打开阀门; Liquid measurement: In the process of opening the valve , in order to avoid the sudden opening of the valve and the formation of water head impact, which will cause the instrument to be damaged, the valve must be opened slowly;

2   要不然的话 如果阀门被突然打开,浮子将 急速冲向止动器,并有可能损坏仪表,所以 在使用的时候 一定 要缓慢地打开阀门。 Gas measurement: Before putting into operation, do not pressurize the pipeline. Otherwise, if the valve is suddenly opened, the float will rush to the stopper and may damage the meter, so be sure to open it slowly when in use. valve. 减小浮子的震荡 The gas measuring instrument can be equipped with a pneumatic damping device to minimize the vibration of the float .

      正确 后才能通电。 For intelligent indicators, first ensure that the electrical wiring is correct, and then check the power before powering on. 容易使仪表产生故障; 对于按键的操作,一定要按照使用说明书正确进行,不要盲目操作,否则会造成仪表内EEPROM 存储的数据丢失或 损坏; Otherwise, it is easy to cause the meter to malfunction; for the operation of the keys, be sure to follow the instruction manual correctly, do not operate blindly, otherwise the data stored in the meter's EEPROM will be lost or damaged;

      大于90% ,没有 日晒 及腐蚀性气体侵蚀的场所; 隔爆型仪表在现场维护需要打开壳体 ,一定要断开电源。 The instrument should be stored at -40 ~ 55 , the relative humidity should not be greater than 90% , there is no place where the sun and corrosive gas attack; and the explosion-proof instrument must be opened when the field maintenance requires cut off the power.
