3151智能型双法兰液位计原理及其作用，当测量具有腐蚀性或含有结晶颗粒，以及粘度大、易凝2113固等介质的测量时，为解决引压管线腐蚀或堵塞的问题，可以采用法兰式差压变送器变送器的法兰直接与容器上5261的法兰连接，作为敏感元4102件的测量头1（金属膜盒）经毛细管2与变送器的测量室相连通，在膜盒、毛细管和测量室所组成的封闭系统内充满硅油，作为传压介质，起到变送器与被测介质隔离的作用。
The principle and function of 3151 intelligent double flange liquid level meter. When measuring corrosive or crystalline particles, as well as high viscosity, easy to condense 2113 solid and other media, in order to solve the problem of corrosion or blockage of impulse pipeline, flange of flange type differential pressure transmitter transmitter can be directly connected with 5261 flange on the vessel as the measuring head 1 (metal capsule) of 4102 sensitive elements ）It is connected with the measuring chamber of the transmitter through capillary 2, and filled with silicone oil in the closed system composed of capsule, capillary and measuring chamber. As a pressure medium, it plays the role of isolating the transmitter from the measured medium.
这要看安装位置预留的孔有多大，反向安装法兰有多大。
It depends on the size of the hole reserved in the installation position and the size of the reverse installation flange.
另外要看 前端伸入罐中的 部分直径多大。
In addition, it depends on the diameter of the part that the front end extends into the tank.
3151智能型双法兰差压液位变送器法兰接口大小选择/电容液位计常见螺纹安装而少用法兰安装。
It is common to install the capacitance liquid level meter with thread but less flange.
按照差压式液位变送器的使用原理:
According to the operation principle of differential pressure liquid level transmitter:
带毛细管的双法兰测液位时，液位计的安装位置（高度）对测量没有影响；
When the liquid level is measured by double flange with capillary, the installation position (height) of the liquid level gauge has no influence on the measurement;
带毛细管的单法兰测液位时，液位计的安装位置（高度）与下接口一致，可以避免迁移的麻烦，如果不等高，安装完成进料前进行一次迁移，将零位对准即可
When measuring the liquid level with single flange with capillary, the installation position (height) of the liquid level gauge is the same as the lower interface, which can avoid the trouble of migration. If the height is not equal to the height, the migration shall be carried out once before the installation and feeding, and the zero position can be aligned
双法兰只用一个测液位时，只需将两个法兰置于同等高度，液位计的安装位置（高度）对测量没有影响；
When only one flange is used to measure the liquid level, only two flanges need to be placed at the same height, and the installation position (height) of the liquid level gauge has no effect on the measurement;
3151智能型双法兰差压液位变送器法兰接口大小选择/注意：上面的“安装位置对测量没有影响”只是理论上的，实际上当两法兰的高度差或单法兰与变送器的高差，所引起的毛细管内液柱压力超过量程时，有些液位计会失常，这和变送器制造水平相关
Note: the above "installation position has no effect on measurement" is only theoretical. In fact, when the height difference between two flanges or the height difference between a single flange and the transmitter causes the liquid column pressure in the capillary to exceed the measuring range, some liquid level meters will malfunction, which is related to the manufacturing level of the transmitter
