智能电容液位计（HART）

      

智能电容液位计适用于容器内导电、非导电介质液位测量，利用液位变化与其对测量传感器产生的电容变化成正比的关系，输出相应的两线制4～20mA标准电流信号。传感器在测量过程中自动适应介质的变化，能够对介质介电常数的变化自动进行补偿。可广泛应用于化工、石油、食品、电力、冶金等领域，特别适合对各种规格的锅炉汽包、高加、低加、中小锅炉等压力容器的液位进行测量。

The intelligent capacitance level gauge is suitable for measuring the liquid level of conductive and non-conductive media in containers. It utilizes the relationship between the liquid level change and the capacitance change generated by the measuring sensor to output the corresponding two wire 4-20mA standard current signal. Sensors automatically adapt to changes in the medium during the measurement process and can automatically compensate for changes in the dielectric constant of the medium. It can be widely used in fields such as chemical, petroleum, food, electricity, metallurgy, etc., and is particularly suitable for measuring the liquid level of various specifications of pressure vessels such as boiler drums, high pressure heaters, low pressure heaters, and small and medium-sized boilers.
