The integrated ultrasonic level gauge is a liquid level measurement device that integrates ultrasonic sensors and data processing controllers in the same housing. With the advantage of non-contact measurement, it is widely used in multi industry liquid level monitoring.
The built-in ultrasonic sensor of the device emits high-frequency ultrasonic signals to the measured liquid level. After the signal contacts the surface of the liquid level, it is reflected, and the reflected signal is received by the same sensor and transmitted to the internal controller. The controller combines temperature compensation to correct the ultrasonic propagation speed, calculates the distance from the sensor to the liquid level surface based on the time difference between signal transmission and reception, and then converts it to the actual liquid level height. The data is then output in a specific signal form for subsequent use.
Its core working principle is that the sensor (probe) on the top of the device emits high-frequency ultrasonic pulses, which are reflected back when they encounter the surface of the measured medium and are received by the same sensor. By accurately calculating the time interval between the emission and reception of sound waves, combined with the speed of sound, the distance from the sensor to the surface of the medium can be calculated, thereby obtaining the level data.
Technical Features
Non contact measurement: does not require direct contact with liquids, avoids corrosion and pollution problems, extends equipment life, especially suitable for corrosive, easily adhesive or polluting liquids (such as acid-base solutions, sewage).
High precision and high stability:
The measurement accuracy can reach ± (0.2% distance+0.05% range), and the resolution varies with the range (such as 1mm for<2m and 2mm for 2-5m).
Some models support dual mode measurement of liquid level and distance, adapting to different scene requirements.
Wide range coverage: The range is usually 4-25 meters, and optional models include 4m, 6m, 8m, 10m, 15m, 25m, meeting the needs of tank, water tank, reservoir and other scenarios.
Application scenarios
Petrochemical industry: liquid level monitoring of storage tanks and reaction vessels, suitable for high temperature, high pressure, and corrosive media environments.
Water treatment: water level monitoring of reservoirs, sedimentation tanks and sewage treatment plants should deal with foam, suspended solids and other disturbances.
Food and beverage: Accurate control of raw material and finished product quantities during the production process to avoid contamination risks.
Other fields: open channel flow measurement, shallow water tank monitoring, etc.
