Measuring gas volumes using electromechanical exciter excited with set frequency in vehicle fuel tank

Measuring gas volumes using electromechanical exciter excited with set frequency in vehicle fuel tank

The measurement method uses an electromechanical exciter (1), which by electrical values is excited with a predetermined excitation frequency to produce oscillation. The exciter together with the gas volume (5) in a container (3) form an oscillating system. The excitation frequency is so selected, t...

description The measurement method uses an electromechanical exciter (1), which by electrical values is excited with a predetermined excitation frequency to produce oscillation. The exciter together with the gas volume (5) in a container (3) form an oscillating system. The excitation frequency is so selected, that no sound reflection can be formed, and the electrical values resulting from the operation of the exciter, are used for measuring the gas volume. The output value of the oscillating system is its electrical impedance. The output value of the oscillation system is its electrical resonance frequency. The quality of the oscillation system is influenced by mechanical damping. The quality of the oscillation system is influenced by electric or electronic measures.
