Ultrasonic Level Transmitters Applications
Measurement of liquid level in water pools, sewage pools, etc.
Ultrasonic Level Transmitters are widely used in level meter measurement projects in water plants, wastewater treatment plants, chemical reagent plants, dye plants, pulp mills and other factories. It is one of the main level measurement methods in modern intelligent automation industry.
Tank liquid level-liquid level difference monitoring
Ultrasonic level measurement technology has unique advantages in measuring tank liquid level. One common method is to make a hole on the top of the tank and install an ultrasonic level sensor for measurement. Another method is to use an external sensor. For tanks that cannot be opened, an ultrasonic level sensor can be attached externally. It is convenient and efficient.
Diesel and other oil storage tank liquid level measurement
For diesel tanks or other oil tanks, explosion-proof ultrasonic level transmitters can meet the measurement requirements. And can be configured with signal output and relay output. Can be used for tank high and low level alarm.
Water level monitoring in lakes, reservoirs, shallow seas, etc.
Ultrasonic level measurement technology is suitable for water level measurement in rivers, lakes, reservoirs, estuaries, channels, ship locks and various hydraulic structures. This real-time monitoring capability can help water conservancy departments to understand water level conditions in a timely manner, predict floods, and provide accurate data support for reservoir scheduling and flood control decisions.

Ultrasonic Level Transmitter Working Principle
Ultrasonic level meter working principle:
Ultrasonic waves propagate in gas, liquid and solid with a certain propagation speed. When propagating in the medium, ultrasonic waves will be absorbed and attenuated. The attenuation in gas is the largest. The attenuation in solid is the smallest.
Ultrasonic waves will reflect and refract when passing through the interface of two different media. For interfaces with large differences in acoustic impedance, it is almost total reflection.
The time interval from transmitting ultrasonic waves to receiving the transmitted signal is related to the position of the interface. Ultrasonic level meters use this characteristic of ultrasonic waves to measure the level.
The transmitter and receiver of ultrasonic level meters can be installed at the bottom or the top of the container. The transmitted ultrasonic waves are emitted at the interface and received by the receiver. By measuring the time interval from the transmission to the reception of ultrasonic waves, the height of the object can be measured.
As shown in the figure below: The speed of sound in the medium is c. The time difference between the echo and the transmitted pulse is t. Then, according to the formula D=c×t/2, the distance D between the sensor and the surface of the object is calculated.
Please understand the measurement principle of ultrasonic level meters in conjunction with the figure below. The calculation formula is: L=E-D. E is the empty tank distance. F is the measuring range (full tank distance). L is the material level. BD is the measurement blind area. D is the distance from the sensor housing plane to the liquid surface (or material surface).
