作为在立足西北,恩泽西北地区工业自动化进程,在在西安液位变送器厂家生产的过程中,时长会提到3151双法兰液位计在密闭管上的安装特点的使用,差压液位变偶送器是在石油化工,市政控制中都有非常重要的使用.

双法兰液位变送器在密闭管上的安装的原理:
双法兰液位计用于防止管道中的介质直接进入变送器里,感压膜片与变送器之间靠注满流体的毛细管连接起来。它用于测量液体、气体或蒸汽的液位、流量和压力,然后将其转变成4~20mA DC信号输出。
差压液位变送器产品特点
●逐台进行模拟“在线运行”考核,保证变送器在极限环境温度、介质温度和工作压力(包括正压或真空)下,稳定而可靠地工作。
  ●采用“动态型面”远传膜片结构,超载后膜片不会受损;长期工作后精度不会发生变化。
  ●选用全熔焊和刚性密封结构的灌充系统,根除了漏油现象的发生。
  ●设计新颖的毛细管结合部件,使毛细管得到可靠的保护,在现场使用不易折断。
  ●品种、形式和尺寸多样的远传装置,以及丰富的灌充液种类,可以满足各种不同场合的测量需要。
  ●可提供各种特殊需要产品,包括高温、高真空、快响应和不等长毛细管(差值≤4.5米)远传差压变送器。双法兰液位变送器在密闭管上的安装时产品有以下特点:
When the double flange liquid level transmitter is installed on the closed pipe, the product has the following characteristics:
1、结构简单牢固,无可动部件,可靠性高,长期运行十分可靠。
1. The structure is simple and firm, no moving parts, high reliability, long-term operation is very reliable.
2、安装简单,维护十分方便。
2. It is easy to install and maintain.
3、检测传感器不直接接触被测介质,性能稳定,寿命长。
3. The sensor has stable performance and long service life without direct contact with the measured medium.
4、测量的是与流量成正比的脉冲信号,无零点漂移,精度高。
4. The pulse signal measured is proportional to the flow rate, with no zero drift and high accuracy.
5、测量范围宽,量程比可达1: 50。
5. The measurement range is wide and the range ratio can reach 1:50.
6、压力损失较小,运行费用低,更具节能意义。
6. The pressure loss is small, the operation cost is low, and it is more energy-saving.
7、采用超低功耗技术,电池供电可运行两年以上。
7. With ultra-low power consumption technology, the battery can run for more than two years.
8、温压补偿一体化设计,同时显示流量值与累积流量值,温度、压力值,不必轮流切换。
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.
3151双法兰液位计在密闭管上的安装特点/安装注意事项
Installation features of 3151 double flange liquid level gauge on closed pipe
1、在线密度计传感器部分间距最少为200mm,直径为50mm, 现场不能小于这些尺寸安装,如选择弯曲型密度计,请测量好可以伸进管内的法兰和长度尺寸。
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、现场液体必须保持没过两个测量传感器,法兰到第一个传感器的距离可选。
2. The liquid on site must not exceed two measuring sensors, and the distance from the flange to the first sensor is optional.
3、管道安装时需让液体从最下面传感器之下进入液体,或者从最上面传感器的上面进入液体,不要从中间进入液体。管道安装通液体时,管道阀门或者弯头部分至少留出30CM液体缓冲距离。
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、配备电源为24VDC输出4-20mA信号如需接二次用表,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、现场环境如果外部有腐蚀性液体,请做好防护措施。如果有雷击危险,请在周围做好引地装置。
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、如需拆卸做清洗时,拆装时请保证传感器膜片不受到碰撞及其它损坏。
6. If it needs to be disassembled for cleaning, please ensure that the sensor diaphragm is not damaged by collision and other damage.
7、请勿在高出5Mpa情况下使用。
7. Do not use it above 5MPa.
8、如果需要调整量程需要用手持器,  技术问题请联系华恒.
8. If you need to adjust the range, you need to use a handheld, please contact Huaheng for technical problems

双法兰液位变送器在密闭管上使用采用先进的隔离型扩散硅敏感元件或陶瓷电容压力敏感传感器制作而成,将静压转换为电信号,再经过温度补偿和线性修正,转化成标准电信号(一般为4~20mA/1~5VDC)的一种测量液位的压力传感器,又可以称之为“静压液位计、液位变送器、液位传感器、水位传感器”。
