SS304 Ultrasonic Level Transmitter,
220VAC Liquid Level Transmitter,
220VAC ultrasonic water tank level meter
The NYCSUL Ultrasonic Level Measurement is mounted on top of the vessel. Under the control of the electronic unit, the probe emits ultrasonic wave pulse to measured medium. The sound wave is reflected by the surface of medium, a part of reflection echo is received by the probe and converted into electrical signal. From the emission of the ultrasonic wave to the new reception,the time is direct proportion to the distance from the probe to the measured medium. The electronic unit detects the time and calculates out the easured distance according to the known sound velocity. Use subtraction to obtain the value of medium position. It is widely used in open pipe, oil tank, pump station, water tower, dam,open channel, difference between levels etc.

Ultrasonic Level Transmitter Operating Principle
The ultrasonic level meter is installed at the top of the container. Under the control of the electronic unit, the probe transmits a beam of ultrasonic pulse to the object under the control of the electronic unit. The acoustic wave is reflected by the surface of the object. Some of the reflected echoes are received by the probe and converted into electrical signals. According to the time difference between retransmission and re-receiving of ultrasonic wave and the known speed of sound, the change of object level is determined. The microwave signal is processed by electronic device, and finally transformed into electrical signal related to object level.
