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

雙法蘭液位變送器選型的時(shí)候尤其要注意一個(gè)很重要的因素，就是差壓式液位變送器，它是安裝在液體容器的底部，通過表壓信號來反映液位的高度。在制藥、化工行業(yè)的液位測量的控制過程中，盛裝液 體的容器經(jīng)常處于有壓的情況下，此時(shí)常規(guī)的靜壓式液位變送器變不能滿足測量要求，由于在傳感器電路和結(jié)構(gòu).上的改進(jìn)，提高了差壓液位測量技術(shù)在制藥和食品行業(yè)的實(shí)用價(jià)值。/3151智能型雙法蘭液位變送器選型手冊(雙語通用)
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.
遠(yuǎn)傳差壓變送器選型遠(yuǎn)傳變送器是在變送器主體基礎(chǔ)上附加遠(yuǎn)傳裝置的變型所以其選型工作行:首先確定變送器主體的類型(DP)、測量范圍和結(jié)構(gòu)材料,然后按現(xiàn)場的安裝要求確傳裝置類型和丿組成灌充系統(tǒng)的各參數(shù)(如灌充液的工作溫度、粘度和毛細(xì)管的長度)與變送器的性能指標(biāo)密切相關(guān),因此歸入變送器主體選型范疇,不單獨(dú)列表選擇
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
