摘要: There is provided a meter for measuring the molecular weight of gas, comprising housing having an inlet and interior receiving said gas to be measured, sensor assembly high-frequency planar piezoelectric crystal oscillator located within so that, in use, contact with being arranged: drive such that resonates at single resonant frequency; measure frequency determine density gas; from density, determined or pre-determined pressure temperature gas.
