Most levitation type liquid level meter and capacitance level gauge both,
Levitation type liquid level meter is maximum by wobble effects, and rapid wear bad influence is used.Capacitance level gauge output signal has non-linear,
Parasitic capacitance and distribution capacity have considerable influence to sensitivity and certainty of measurement.Not only two sensor accuracy class easily receive environment
Affect, and a sensor be only installed mostly when being installed in gas cylinder to cause easily occur deviation in use.
Ultrasonic sensor has advantages below in addition：(1) do not contact with medium, without movable member, electronic component only with
Acoustic frequency vibration, amplitude are little, and device longevity is long；(2) ultrasonic propagation velocity is more stable, light, dielectric viscosity, humidity, dielectric
Constant, electrical conductivity, thermal conductivity etc. are on detecting almost without impact, therefore are applied to the special occasions such as poisonous, corrosivity or high viscosity
Level gauging；(3) not only continuously can be measured and one-point measurement, moreover it is possible to which remote measurement or remote signal are easily provided；(4) energy
Measurement high-speed motion has the liquid level of liquid that inclination rocks.
