3151智能型雙法蘭液位計原理及其作用，當測量具有腐蝕性或含有結晶顆粒，以及粘度大、易凝2113固等介質的測量時，為解決引壓管線腐蝕或堵塞的問題，可以采用法蘭式差壓變送器變送器的法蘭直接與容器上5261的法蘭連接，作為敏感元4102件的測量頭1（金屬膜盒）經毛細管2與變送器的測量室相連通，在膜盒、毛細管和測量室所組成的封閉系統內充滿硅油，作為傳壓介質，起到變送器與被測介質隔離的作用。
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.
這要看安裝位置預留的孔有多大，反向安裝法蘭有多大。
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 部分直徑多大。
In addition, it depends on the diameter of the part that the front end extends into the tank.
3151智能型雙法蘭差壓液位變送器法蘭接口大小選擇/電容液位計常見螺紋安裝而少用法蘭安裝。
It is common to install the capacitance liquid level meter with thread but less flange.
按照差壓式液位變送器的使用原理:
According to the operation principle of differential pressure liquid level transmitter:
帶毛細管的雙法蘭測液位時，液位計的安裝位置（高度）對測量沒有影響；
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;
帶毛細管的單法蘭測液位時，液位計的安裝位置（高度）與下接口一致，可以避免遷移的麻煩，如果不等高，安裝完成進料前進行一次遷移，將零位對準即可
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
雙法蘭只用一個測液位時，只需將兩個法蘭置于同等高度，液位計的安裝位置（高度）對測量沒有影響；
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智能型雙法蘭差壓液位變送器法蘭接口大小選擇/注意：上面的“安裝位置對測量沒有影響”只是理論上的，實際上當兩法蘭的高度差或單法蘭與變送器的高差，所引起的毛細管內液柱壓力超過量程時，有些液位計會失常，這和變送器制造水平相關
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
