钢带浮子液位指示器“原理结构” The principle structure

1. 液位计是根据力平衡原理来测量容器内的液位的，在力平衡状态下，当液位处于某一高度时，浮标重量W减去浮标浸在液体中的浮力F. 减去重锤重量W1，减去测量系统中的摩擦力f等于零， W－F－W1－f=0或W1=W－F－f,重锤指示的即为容器内的液位高度;

Liquid level meter is to measure the liquid level in the container according to the principle of force balance, in the balance state, when the liquid level is at a certain height, W weight minus buoy buoy is immersed in liquid buoyancy F. minus W1 minus the hammer weight, friction measurement system f is equal to zero, the W - F - W1 －f=0 or W1=W－F－f the weight indicator, which is the height of the liquid level in container;

2. 液位计由标尺. 重锤指针. 导轮. 导向钢丝及浮标等组成;

Liquid level gauge from the scale. The hammer. The pointer. A guide wire and buoy;

钢带浮子液位指示器“安装” Installation

1. 两根导向钢丝必须平行，与容器底边垂直，两端需要固定与拉紧;

Two guide wire must be parallel, vertical and container bottom, both parties need fixing and tensioning;

2. 钢带浮标处在容器底部时，垂锤指针应指向零位，浮标处在液位上，垂锤指针应指向满量程;

Strip the buoy at the container bottom, vertical hammer pointer pointing to zero, the buoy at the level cap, vertical hammer pointer pointing to a full-scale;

3. 出厂液位计为装零部件，客户自行就地安装;

The factory level gauge is installed components, the client to be installed;
