The digital liquid level instrument of device control.Ultrasonic pulse is issued by energy converter in the measurements, and sound wave is same after liquid surface reflects
One sensor receives, and is converted into electric signal by piezo-electric crystal or magnetostrictive device, and by between the transmitting and reception of sound wave
Time come calculate sensor to fluid to be measured surface distance.Due to use non-contacting measurement, measured medium hardly by
Limitation, can be widely used for the measurement of various liquid and solid material height.
Ultrasonic wave is one kind of mechanical wave, is mechanical oscillation in one of elastic fluid communication process, it is characterized in
Frequency is high, wavelength is short, diffraction phenomenon is small, in addition good directionality, can become ray and direction propagation.Ultrasonic wave is in liquid, solid
Decay very little in body, thus penetration capacity is strong, and especially in the solid opaque to light, ultrasonic wave can penetrate tens meters of length
Degree, encounters impurity or interface and just has significant reflection, ultrasonic measurement level is exactly that its this feature is utilized.Ultrasonic wave
There is a blind area, when installation, which must calculate, reserves the distance between sensor mounting location and measurement liquid.
The working principle of ultrasonic level gage is to issue high-frequency impulse sound wave by ultrasonic transducer to encounter tested level table
Face is turned back by reflection, and reflection echo is converted into electric signal by energy converter reception.Propagation time of sound wave and sound wave are issued to object
The distance in body surface face is directly proportional, and sonic transmissions distance S and the relationship of velocity of sound C harmony transmission time T can be formulated: S=C ×
T/2。
