作為在立足西北,恩澤西北地區工業自動化進程,在在西安液位變送器廠家生產的過程中,時長會提到3151雙法蘭液位計在密閉管上的安裝特點的使用,差壓液位變偶送器是在石油化工,市政控制中都有非常重要的使用.
雙法蘭液位變送器在密閉管上的安裝的原理：
雙法蘭液位計用于防止管道中的介質直接進入變送器里，感壓膜片與變送器之間靠注滿流體的毛細管連接起來。它用于測量液體、氣體或蒸汽的液位、流量和壓力，然后將其轉變成4～20mA DC信號輸出。
差壓液位變送器產品特點
●逐臺進行模擬“在線運行”考核，保證變送器在極限環境溫度、介質溫度和工作壓力（包括正壓或真空）下，穩定而可靠地工作。
●采用“動態型面”遠傳膜片結構，超載后膜片不會受損；長期工作后精度不會發生變化。
●選用全熔焊和剛性密封結構的灌充系統，根除了漏油現象的發生。
●設計新穎的毛細管結合部件，使毛細管得到可靠的保護，在現場使用不易折斷。
●品種、形式和尺寸多樣的遠傳裝置，以及豐富的灌充液種類，可以滿足各種不同場合的測量需要。
●可提供各種特殊需要產品，包括高溫、高真空、快響應和不等長毛細管（差值≤4.5米）遠傳差壓變送器。雙法蘭液位變送器在密閉管上的安裝時產品有以下特點:
When the double flange liquid level transmitter is installed on the closed pipe, the product has the following characteristics:
1、結構簡單牢固，無可動部件，可靠性高，長期運行十分可靠。
1. The structure is simple and firm, no moving parts, high reliability, long-term operation is very reliable.
2、安裝簡單，維護十分方便。
2. It is easy to install and maintain.
3、檢測傳感器不直接接觸被測介質，性能穩定，壽命長。
3. The sensor has stable performance and long service life without direct contact with the measured medium.
4、測量的是與流量成正比的脈沖信號，無零點漂移，精度高。
4. The pulse signal measured is proportional to the flow rate, with no zero drift and high accuracy.
5、測量范圍寬，量程比可達1: 50。
5. The measurement range is wide and the range ratio can reach 1:50.
6、壓力損失較小，運行費用低，更具節能意義。
6. The pressure loss is small, the operation cost is low, and it is more energy-saving.
7、采用超低功耗技術，電池供電可運行兩年以上。
7. With ultra-low power consumption technology, the battery can run for more than two years.
8、溫壓補償一體化設計，同時顯示流量值與累積流量值，溫度、壓力值，不必輪流切換。
8. Temperature and pressure compensation integrated design, display flow value and cumulative flow value, temperature and pressure value at the same time, do not need to switch in turn.

Installation features of 3151 double flange liquid level gauge on closed pipe
1、在線密度計傳感器部分間距最少為200mm,直徑為50mm, 現場不能小于這些尺寸安裝,如選擇彎曲型密度計,請測量好可以伸進管內的法蘭和長度尺寸。
1. The distance between sensors of on-line densitometer shall be at least 200 mm and the diameter shall be 50 mm. The installation shall not be less than these dimensions on site. If bending densitometer is selected, please measure the flange and length that can be extended into the pipe.
2、現場液體必須保持沒過兩個測量傳感器,法蘭到第一個傳感器的距離可選。
2. The liquid on site must not exceed two measuring sensors, and the distance from the flange to the first sensor is optional.
3、管道安裝時需讓液體從最下面傳感器之下進入液體，或者從最上面傳感器的上面進入液體，不要從中間進入液體。管道安裝通液體時，管道閥門或者彎頭部分至少留出30CM液體緩沖距離。
3. When installing the pipeline, the liquid should be allowed to enter the liquid from the bottom sensor or from the top of the top sensor. Do not enter the liquid from the middle. When the pipeline is installed with liquid, at least 30cm liquid buffer distance shall be reserved at the valve or elbow part of the pipeline.
4、配備電源為24VDC輸出4-20mA信號如需接二次用表，需接24V“+”
4. It is equipped with a power supply of 24 VDC to output 4-20mA signal. If the secondary meter needs to be connected, it needs to be connected with 24 V "+"
5、現場環境如果外部有腐蝕性液體，請做好防護措施。如果有雷擊危險，請在周圍做好引地裝置。
5. If there is corrosive liquid outside the site environment, please take protective measures. If there is a lightning strike around the device, please do it properly.
6、如需拆卸做清洗時，拆裝時請保證傳感器膜片不受到碰撞及其它損壞。
6. If it needs to be disassembled for cleaning, please ensure that the sensor diaphragm is not damaged by collision and other damage.
7、請勿在高出5Mpa情況下使用。
7. Do not use it above 5MPa.
8、如果需要調整量程需要用手持器, 技術問題請聯系華恒.
8. If you need to adjust the range, you need to use a handheld, please contact Huaheng for technical problems
雙法蘭液位變送器在密閉管上使用采用先進的隔離型擴散硅敏感元件或陶瓷電容壓力敏感傳感器制作而成，將靜壓轉換為電信號，再經過溫度補償和線性修正，轉化成標準電信號（一般為4～20mA/1～5VDC）的一種測量液位的壓力傳感器，又可以稱之為“靜壓液位計、液位變送器、液位傳感器、水位傳感器”。
