In order to further improve the seal of sealed storage tank, tank differential pressure transducer is indispensable. In recent years, most sensor manufacturers have been developing new pressure level sensors to measure the pressure and level of sealed storage tanks, but these new products have been marketed without severe environmental measurements, resulting in a bad reputation.

This tank differential pressure transducer is not a so-called "high-tech" pressure sensor, its main function is to calculate storage top and bottom of the pressure difference, its installation method as shown in the figure below, under normal circumstances, a differential pressure sensor is installed in the bottom of the storage tank, and the other is a drainage pipe connected to the storage tank. The pressure difference between the two ends is used to calculate the level change in the tank, so as to prevent the liquid in the tank from volatilizing or being oxidized.

I believe that some people are concerned about the stability of the differential tank pressure transducer. In fact, its high and low pressure values are in the range of 5 to 40bar, which is basically the pressure level suitable for most sealed storage tanks.
