Differentialpressure remote water gauge should have pressure supplement function to ensure an actual indication of water line in the bubbles under all kinds of working circumstances.
差压式远传水位表应具有压力补偿功能，以保证各种工况下都能显示汽包中真实水位的变化。

The zero and linearity characteristic of differentialpressure transducer is corrected with method of water column correction to ensure higher precision differentialpressure data.
采用水柱校正法对差压传感器的零点及线性特性进行校正以保证高精度的差压数据。
