How can errors be reduced when measuring high-temperature liquid level with a double-flange differential pressure sensor? This article analyzes the effects of fill fluid thermal expansion, changes in medium density, and installation temperature differences, and provides guidance on selection, symmetrical arrangement, temperature compensation, calibration, and maintenance to help improve liquid level measurement stability in applications such as reactors and storage tanks.

The interface specifications of flange differential pressure sensors directly affect sealing safety under high-pressure conditions. This article explains the key verification points for flange standards, pressure ratings, sealing faces, gasket materials, and installation loads, helping chemical, energy, and other projects reduce the risks of leakage and rework and achieve reliable selection.
