Split type ultrasonic liquid level meter

 Ultrasonic level gauge

Yj-cyw series Split type ultrasonic liquid level meter Two wire system, three wire system or four wire system technology can be adopted. The power supply circuit and signal output circuit are independent 24v For power supply, one can be used three Core cable, the negative end of power supply and the negative end of signal output share the same core wire; when using AC 220v When supplying power, or when using DC 24v Power supply: when the power supply circuit is completely isolated from the signal output circuit, one should be used four Core cable. DC or AC power supply with 4~20mADC High low switch output.

 

Yj-cyw series Split type ultrasonic liquid level meter Application range:

YJ-CYW Series split type ultrasonic liquid level meter Due to the non-contact measurement, the measured medium is almost unlimited, which can be widely used to measure the height of various liquid and solid materials.

 

Yj-cyw series Split type ultrasonic liquid level meter Measurement principle:
 Measuring principle of ultrasonic liquid level meter


YJ-CYW Series split type ultrasonic liquid level meter The working principle is that the ultrasonic transducer (probe) sends out high-frequency pulse sound wave. When the sound wave meets the surface of the measured level, it is reflected back and the reflected echo is received by the transducer and converted into electrical signal . The propagation time of sound wave is proportional to the distance from the sound wave to the surface of the object . Acoustic transmission distance S And speed of sound C Harmony transmission time T The relationship between the two can be expressed as follows: S=C×T/2.

The distance between the probe and the liquid surface is proportional to the ultrasonic time

HB = CT2, i.e

distance [m] = time × sound velocity /2 [m]

Temperature compensation formula of sound speed:

Ambient sound velocity = 331.5 + 0.6× temperature
