The double flange liquid level transmitter can avoid the direct contact between the measured medium and the isolation diaphragm of the transmitter, This measurement method is applicable to the following situations: the tested medium has strong corrosion on the transmitter sensitive elements, and the high-temperature measured medium needs to be separated from the transmitter; 3. There is solid suspension or high viscosity medium in the measured medium, and the measured medium is easy to solidify or crystallize; 5. The measured medium needs to be replaced, and the measuring head needs to be cleaned strictly

双法兰液位变送器选型的时候尤其要注意一个很重要的因素，就是差压式液位变送器，它是安装在液体容器的底部，通过表压信号来反映液位的高度。在制药、化工行业的液位测量的控制过程中，盛装液 体的容器经常处于有压的情况下，此时常规的静压式液位变送器变不能满足测量要求，由于在传感器电路和结构.上的改进，提高了差压液位测量技术在制药和食品行业的实用价值。/3151智能型双法兰液位变送器选型手册(双语通用)
When selecting the type of double flange liquid level transmitter, we should pay special attention to a very important factor, that is, the differential pressure type liquid level transmitter, which is installed at the bottom of the liquid container and reflects the height of the liquid level through the gauge pressure signal. In the control process of liquid level measurement in pharmaceutical and chemical industries, the container containing liquid is often under pressure. At this time, the conventional static pressure liquid level transmitter cannot meet the measurement requirements. Due to the improvement of sensor circuit and structure, the practical value of differential pressure liquid level measurement technology in pharmaceutical and food industries is improved.
远传差压变送器选型远传变送器是在变送器主体基础上附加远传装置的变型所以其选型工作行:首先确定变送器主体的类型(DP)、测量范围和结构材料,然后按现场的安装要求确传装置类型和丿组成灌充系统的各参数(如灌充液的工作温度、粘度和毛细管的长度)与变送器的性能指标密切相关,因此归入变送器主体选型范畴,不单独列表选择
Selection of remote differential pressure transmitter remote transmitter is a variant of remote transmitter with remote device attached to the transmitter body, so its selection work is as follows: first, determine the type (DP), measurement range and structural material of the transmitter body, Then according to the site installation requirements, confirm that the device type and parameters of the filling system (such as the working temperature, viscosity of the filling liquid and the length of the capillary) are closely related to the performance index of the transmitter. Therefore, they are included in the selection category of the transmitter main body and are not selected in a separate list
