Claims

[Scope of utility model registration request]

A magnetic float installed in the gas flow path of a medical gas humidifier floats in response to the flow rate of the gas, thereby causing an inductance variable in the oscillator's Tsuremade coil, which is then converted into a frequency variable corresponding to the variable. Equipped with an oscillator for detecting float height that causes the oscillator to oscillate,
A predetermined frequency output wave of a fixed oscillator is applied to the output side of the oscillator of this oscillation section, and a phase detection circuit is connected to the oscillator, and the frequency difference value output of the oscillator obtained by the phase detection circuit is instantaneously It is connected to the instantaneous value counter via the value frequency divider, and the output side of the counter is connected to the integration counter via the integration frequency divider, and the output sides of the instantaneous value counter and the integration counter are connected. A gas meter for medical gas humidifiers that is connected to a switchable display.
