特點(diǎn)features:
＊measures mass flowrate free of influence from pressure changes.
＊since no moving part exists in gas contact area structurally simple and compact(excluding needie valve).
＊dueto temperature compensating circuit incorporated corresponds ro tempeiature changes.
＊no restriction placed on instsllstion.
