一般工厂中都装有锅炉,制造蒸汽供生产或生活需要。锅炉汽泡必须保持适当的液位,以确保安全。为此,任何一台锅炉上都装有液位计显示汽泡内水位的高低。其中最简单的是玻璃平板液位计,水位高低可用肉眼直接透过玻璃观察。但这种玻璃液位计有时会因上下与汽泡相连的根部阀门局部堵塞或有空气而造成假液位,为此必须定期排污检查。同时,这类玻璃液位计只有在炉膛与汽泡相距不远的小型锅炉上才能使用。大锅炉,汽泡与司炉工操作位置相距很远,或因隔着其他建筑物就无法观察,因此就得装较复杂的液面计,先由发送器 General factories are equipped with boilers, steam production for the production or life needs. Boiler bubble must maintain the appropriate level to ensure safety. To this end, any one of the boiler is equipped with a level gauge shows the level of water level in the bubble. One of the most simple is the glass flat liquid level gauge, the level of the water can be observed directly through the glass with the naked eye. However, this glass level gauge sometimes due to the upper and lower connected to the root of the bubble valve is partially plugged or air caused false water level, for which we must regularly check the sewage. At the same time, such glass level gauges can only be used on small boilers that are not far from the bubble in the hearth. Big boiler, bubble and fireman operating position is very far away, or because of other buildings can not be observed, so you have to install a more complex liquid level meter, the first by the transmitter
