In industrial production, environmental monitoring, and civilian facilities, liquid level measurement is the core link to ensure system safety and optimize resource utilization. However, harsh environments such as humidity, dust, and corrosive gases often pose serious challenges to the reliability and accuracy of liquid level gauges.IP68Ultrasonic level gauges, with their fully sealed design, non-contact measurement, and intelligent functions, have become an ideal choice for such scenarios. This article is based onAC100Taking the series as an example, analyze its technical characteristics and application value.

1IP68Protection: Fully sealed structure to cope with extreme environments

IP68It's the International Electrotechnical Commission（IEC）The highest protection level standard established, among which“6”Represents complete dust prevention,“8”Representatives can be present1.5Long term immersion at a depth of meters.AC100The series achieves this goal through the following design:

Shell material: Adopting316LStainless steel or reinforced typePVDFEngineering plastics have better corrosion resistance than ordinary plastics304Stainless steel, suitable for strong corrosion scenarios such as acid and alkali storage tanks and seawater desalination.

Sealing process: The sensor and circuit board are sealed using vacuum sealing technology, filled with epoxy resin or silicone to isolate moisture and dust from entering. For example, in the salt spray environment of coastal chemical plants, the internal circuits of the equipment can be maintained10Over years without corrosion.

Pressure balance: The built-in breathable membrane balances the internal and external air pressure, avoiding deformation of the shell due to temperature changes and preventing water vapor from seeping in.

2、 Non contact measurement: a technological breakthrough with no wear and high adaptability

Ultrasonic level gauges measure by emitting and receiving ultrasonic pulses, without the need for direct contact with liquids, solving the three major pain points of traditional level gauges:

Media compatibility: It can penetrate interference layers such as steam, foam and suspended solids. In the pulp storage tank of the paper mill,AC100Can penetrate10cmThe thick foam layer accurately measures the liquid level, while the float level gauge is prone to false alarm due to foam stagnation.

No mechanical wear and tear: The sensor has no moving parts and has a long lifespan8-10In the year, far exceeding the magnetic flip plate and static pressure level gauge3-5Year.

Wide range coverage: Supports0.25-25Measurement range of meters, a single device can adapt to the needs of laboratory small tanks to large reservoirs.

3、 Intelligent function: improve operation and maintenance efficiency

Automatic temperature compensation: Built in high-precision temperature sensor, real-time correction of sound velocity (sound velocity changes at a rate of approximately with temperature)0.6m/s/℃）Ensure that in-20℃to70℃Accuracy within a wide temperature range±0.25%FS.

Empty cans/Full tank calibration: Users can input the tank height through buttons or upper computer software, and complete zero and full range calibration with one click, reducing debugging time to5Within minutes.

Fault self diagnosis: When the echo signal strength is below the threshold (such as low liquid level or sensor contamination), the equipment automatically triggers an alarm and passes485Upload fault codes through the interface for quick problem identification.

4、 Typical application scenarios

Water treatment industry: In the regulating tanks and aeration tanks of sewage treatment plants,AC100TolerableH₂SWaiting for corrosive gases, the linked pump station realizes automatic liquid level control to avoid overflow fines.

In the field of chemical engineering, the liquid level of storage tanks for hazardous chemicals such as concentrated sulfuric acid and liquid alkali is monitored. The non-contact design eliminates the risk of medium leakage and meets the requirementsATEXExplosion proof standards.

Agricultural irrigation: powered by solar energyAC100The liquid level gauge can be installed in reservoirs in remote areas, and data can be uploaded to the cloud platform through wireless modules to achieve remote irrigation scheduling.

Food processing: In the fermentation tanks of dairy products and beer, ultrasound can penetrate the vapor layer to measure the liquid level, and316LStainless steel material meets the requirementsFDAHygiene standards.

Conclusion

IP68Ultrasonic level gauge passed through“Fully sealed protection+Non-contact measurement+Intelligent compensation”The combination solves the problem of liquid level monitoring in harsh environments such as humidity, corrosion, and dust. its8-10The long lifespan and low maintenance requirements of the year further reduce the total lifecycle cost. With the advancement of industry4.0With the increasing demand for process control accuracy, such equipment will continue to provide key support for the digital transformation of industries such as energy, environmental protection, and agriculture through technological innovation.
