MDD has high pressure resistance and high anti-corrosive performance. The diaphragm type pressure gauge is mainly use for the positive and negative pressure port of the filter. It is suitable for measuring differential pressure of liquid level, pump inlet and outlet, oil pipeline, pipeline gas and pressurize pump station.
