雙膜片式高靜壓差壓表主要用于過濾器的正負(fù)壓力端,液體灌液位、 泵出入口、 輸油管線、 輸氣管線和加壓泵站等場(chǎng)合的壓力差的測(cè)量。 本儀表具有較高的耐壓性能, 并適合于在有腐蝕性的環(huán)境中使用。
Mainly used for measuring the difference between two pressure
values, in the plus and minus ends of filter, the level of liquid, the
entrance and exit of pump, oil pipeline, gas pipeline and high
pressure pump station and so on. It is excellent while overpressure
take place, also suitable for corrosion environments.
