Level instrument
Boiler magnetic water level meter

是根据磁性原理、阿基米德(浮力定律)等原理巧妙地结合机械传动的特性而开发研制的一种专门用于液位测量的装置;其中DX-FO型是最基本的一种产品,其余的各种产品都是在其基础上的延伸;在检测液位的同时我们赋予它们更多的实用功能。 The boiler magnetic water level meter is a device specially developed for liquid level measurement based on the magnetic principle, Archimedes (buoyancy law) and other principles. A kind of product, and the rest of the various products are based on its extension; while detecting the liquid level, we give them more practical functions.
的工作原理作一简单的介绍。 Before you choose this product, we will briefly introduce the working principle of the boiler magnetic water level meter . It has a cavity that holds the float. We call it the main body tube or shell. It forms a connector with the container through a flange or other interface. In this way, the liquid level in the cavity is the same as the liquid level in the container, so The floating ball in the cavity will rise and fall with the rise and fall of the liquid level in the container; at this time we cannot see the liquid level, so we installed a flip-column display outside the cavity, because we were floating when we made the floating ball. Magnetic steel is installed at the interface between the ball sinking liquid and the floating part. When the ball and the floating ball rise and fall with the liquid level, its magnetism is transmitted to the flip column display through the shell, pushing the magnetic flip column to turn 180 °; It is a cylinder composed of two red and white semi-cylindrical columns, so after turning 180 °, it will change the color (red below the liquid surface and white above) after facing the column display, and the junction of the two colors is the height of the liquid surface.
是在翻柱液位计的基础上增加了磁控开关,在监测液位的同时磁控开关信号可用于对液位进行控制或报警;远传型是在翻柱液位计的基础上增加了4~20mA 变送传感器,在现场监测液位的同时将液位的变化通过变送传感器、线缆及仪表传到控制室,实现远程监测和控制。 The control boiler magnetic water level meter is based on the column-turning liquid level gauge, which adds a magnetic control switch. While monitoring the liquid level, the magnetic switch signal can be used to control or alarm the liquid level. A 4-20mA transmission sensor is added to the position meter, and the liquid level change is transmitted to the control room through the transmission sensor, cable and instrument while monitoring the liquid level on the spot to achieve remote monitoring and control.
