锅炉汽包水位测量的重要性是人所共知的，然而长期以来锅炉汽包水位连续测量技术方面采用的平衡容器式（差压式）测量方法存在许多无法改进的缺陷，主要体现在以下几个方面： It’s well known that the measurement on fluid level of boiler drum is very important, but for a long time, the balance conteiner type (Pressure Gradient type) used for the continuous measurement technology of boiler drum fluid level has had many defects that could not be improved, it mainly embodied in the following aspects:

   1、不能实施全工况测量，存在“假水位”测量、在锅炉启、停、排空、连排、事故等不稳定运行工况下建立稳定差压条件时间较长、恢复时间较长或干脆不能建立正常差压，需要人工干预等问题。It cannot perform the measurement under all states, ａnd still exists following problems: the measurement on “shrink ａnd swell in drum boilers”, too long a time to set up steady pressure gradient under the unstable operating conditions such as start. S, drain, constant discharge ａnd accident of boilers; too long a time to recover or cannot set up the normal pressure gradient; need manual intervention etc; 
    2 、在稳定工况条件下，由于受结构限制，不能彻底解决因水侧绝温造成的系统测量误差的补偿问题。在锅炉缺、满水等事故工况条件下，系统测量误差过大可能带来严重后果 Under the steady operating conditions, because of structural limitation, it cannot completely solve the problem for the compensation of system measurement error due to temperature insulation on the water side. While in the accident operating conditions such as lack/ full of water in boiler, the too large error of system measurement may result in serious consequences accordingly. 
    3、结构复杂，静密封点多，施工规模大并存在冬季保温问题。The structure is quite complex, too much static sealing points were required, construction size is large ａnd the existed problem for heat preservation in winter;
    4、测量时滞较长，不能即时反应锅炉水位变化，测量信号调节质量差。 Time-lag for measurement is too long, cannot reflect the fluid level changes inside the boiler instantly, the measuring signal has quite poor adjustment quality;
    5、由于存在冷凝筒放热，使用成本高。 Because of condensation drum heat radiation, it causes too higher using cost.
    这些缺陷都是由于差压式测量原理及其对系统取样结构的不合理造成的，无法改进。在非正常工况下给锅炉安全运行造成了大隐患。为彻底解决汽包水位测量存在的问题，我公司针对锅炉汽包水位测控工况业设计生产出FY2G系列智能锅炉汽包液位计 Those defects are all generated from the principle of pressure gradient measurement ａnd the irrational sampling structure of system, ａnd cannot be improved at all. Under the abnormal operating conditions it may cause great hidden trouble for the safety operation of boiler. To completely solve such existing problem for the fluid level measurement on boiler drum, aimed to the measurement ａnd control operating conditions for fluid level of boiler drum, our company has developed ａnd manufactured the intelligent boiler drum fluid level gauge in FY2G series in specialty. 

1、 具有全工况条件下液位准确连续测控功能。 It has the continuous measurement function on the fluid level under all operating conditions;

2、 能够对液相介质、介电常数变化、汽相介质、介电常数变化同时进行自动补偿。It can make the automatic compensation on both the liquid phase medium & dielectric constant change, vapor phase medium & dielectric constant change at the same time;

3、 按键调整、轻松标定、带自诊断，全温度范围、测量系统，温漂不超过0.1PF，电采用非金属材质，机电体化。 With the measurement system in key adjustment, easy calibration, self-diagnosis ａnd full temperature range, its temperature drift will not exceed 0.1PF ａnd the electrode was made with non-metal material, with mechanical-electrical integration.

4、 FY2G系列智能锅炉汽包液位计耐高温、高压、寿命长、高可靠、高精度、高稳定。The intelligent boiler drum fluid level gauge in FY2G shall have the advantages of high-temperature/ pressure resistance, long service life, with high reliability, high accuracy ａnd high stability.

5、 适用于各种规格的工业锅炉、汽包等压力容器的液位测控。It can be applied for the fluid level measurement ａnd control on those pressure vessels as the industrial boiler ,steam drum in various specifications.
