Ultrasonic level gauge

Ultrasonic level gauge, as a non-contact measuring device based on the principle of ultrasonic waves, has become one of the mainstream products in the field of level measurement due to its accuracy, stability, and wide applicability.

Ultrasonic level gaugeThe core working principle of is based on the "echo ranging" technology, and the entire measurement process does not require direct contact with the measured medium, effectively avoiding the impact of medium corrosion, adhesion and other problems on the equipment. The workflow mainly consists of four steps: firstly, the ultrasonic transducer (probe) of the equipment emits high-frequency ultrasonic pulse signals to the surface of the measured liquid under the control of the electronic unit; Secondly, ultrasonic signals reflect off the liquid surface during propagation, forming echo signals; Then, the transducer receives the reflected echo signal and converts it into an electrical signal for transmission to the electronic unit; Finally, the electronic unit processes the electrical signal and calculates the distance between the probe and the liquid surface using the formula "distance=sound speed x time/2" based on the ultrasonic propagation speed (usually based on the speed of sound in the air, which can be automatically compensated according to the ambient temperature) and the round-trip time of the signal. Combined with the preset measurement range (such as the height from the bottom of the tank to the probe), the actual liquid level height of the liquid is finally obtained, and the measurement results are output in digital, analog signals, or wireless transmission.

It is worth noting that high-qualityUltrasonic level gaugeEquipped with * signal processing technology, such as automatic filtering and interference suppression functions, it can effectively eliminate the influence of interference factors such as bubbles, dust, and stirring on the measurement, ensuring stable measurement accuracy under complex working conditions. At the same time, some products also have temperature compensation function, which automatically adjusts the ultrasonic propagation speed by monitoring the environmental temperature in real time, further improving measurement accuracy, especially suitable for scenarios with large temperature fluctuations.

Compared to traditional measuring devices such as radar level gauges, float level gauges, and pressure type level gauges,Ultrasonic level gaugeHaving outstanding advantages in multiple aspects, it occupies an important position in the market.

In addition, the equipment also has good anti-interference ability, which can effectively resist electromagnetic interference, radio frequency interference, etc., ensuring normal operation in complex industrial environments.

Finally,High level of intelligence and convenient operationModernUltrasonic level gaugeCommonly equipped with LCD screens, it can display real-time data such as liquid level height, temperature, and fault information, allowing users to intuitively understand the operating status of the equipment. Some products also support button operation or remote control. Users can set and adjust the parameters of the device through buttons or remote terminals, such as switching measurement units (meters, centimeters, inches, etc.), setting alarm thresholds, resetting data, etc. Meanwhile, manyUltrasonic level gaugeIt also has data storage and transmission functions, which can store measurement data inside the device or transmit it to the upper computer or cloud platform through communication interfaces such as RS485, 4G, LoRa, etc., realizing real-time monitoring of liquid level data, historical data query and data analysis, and providing data support for intelligent management of enterprises.

To ensureUltrasonic level gaugeTo achieve excellent performance in practical applications, users need to pay attention to the following points during the selection and installation process.

atSelection aspectFirstly, it is necessary to clarify the measurement requirements, including the measurement range (i.e. the distance from low to high liquid level, ensuring that the measurement range of the selected equipment covers this distance while reserving a certain margin), measurement accuracy (determining the required accuracy level according to production processes or monitoring requirements, avoiding excessive pursuit of high accuracy leading to cost increase or insufficient accuracy affecting use), characteristics of the measured medium (such as corrosiveness, viscosity, temperature, pressure, whether it contains bubbles or impurities, etc.), and selecting equipment models that match the characteristics of the medium. For corrosive media, probes with anti-corrosion coatings should be selected; for high-temperature media, high-temperature resistant models should be selected. Secondly, it is necessary to consider factors related to the installation environment, such as the size of the installation space, the presence of dust, steam, electromagnetic interference, etc., and choose an installation method and equipment model that is suitable for the environment. In addition, attention should be paid to the functional requirements of the device, such as whether data storage, remote transmission, alarm functions, etc., and products with corresponding functions should be selected according to actual needs. Finally, it is important to choose products produced by reputable manufacturers to ensure product quality and after-sales service, and to avoid any impact on usage due to product quality issues.

atInstallation aspectFirstly, it is necessary to choose a suitable installation location. Top mounted equipment should be installed in the center of the top of the storage tank or container, avoiding being close to the tank wall or the inlet and outlet to prevent liquid fluctuations from affecting the measurement; Side mounted equipment should be installed in areas where the liquid level is stable, avoiding installation in locations where the liquid level fluctuates greatly. Secondly, it is necessary to ensure that the probe is perpendicular to the liquid surface to avoid measurement errors caused by tilting. At the same time, there should be no obstructions below the probe (such as stirrers, brackets, etc.) to prevent ultrasonic signals from being obstructed or reflected, which could affect the measurement results. In addition, attention should be paid to the protective measures of the equipment during installation. For example, when installing outdoors, rain and sun protection covers should be added; In environments with high levels of dust, it is necessary to regularly clean the dust on the surface of the probe to ensure its normal operation. Finally, after installation, the equipment needs to be debugged, including parameter settings (such as measurement range, alarm threshold, etc.), zero calibration, etc., to ensure accurate measurement and stable operation of the equipment.
