XY-GA High Protection Ultrasonic Level Meter: A Reliable Integrated Solution for Non-contact Material Level and Liquid Level Measurement and Control in Complex Working Conditions
In the fields of petrochemical, wastewater treatment, power, metallurgy, mining, and environmental protection, continuous and accurate monitoring of material level and liquid level directly affects production safety, process control, and equipment protection. Traditional contact measurement methods (such as pressure type, capacitive type, and float type) often lead to frequent maintenance and reduced reliability due to medium corrosion, crystallization adhesion, blockage, and leakage problems.
The Nexisense XY-GA cast aluminum ultrasonic level meter is developed based on years of industrial application experience, integrating advanced domestic and international technologies, and adopting a fully digital and user-friendly design concept. The instrument consists of an ultrasonic transducer, a processing unit, and an output unit. It uses piezoelectric ceramics to emit and receive ultrasonic pulses and realizes non-contact material level/liquid level measurement through time-distance conversion. This product completely avoids the winding, blockage, corrosion, and leakage problems of traditional measurement methods, and is particularly suitable for working conditions with strong corrosion (acid, alkali), high adhesion, dust, or severe pollution, providing stable and reliable liquid level/material level data support for DCS, PLC, and SCADA systems.

Typical Application Scenarios
The Nexisense XY-GA high-protection ultrasonic level meter is widely used in projects requiring non-contact, high-reliability material level/liquid level monitoring:
Chemical and Petroleum Storage Tanks: Liquid level measurement of highly corrosive liquids (such as acid and alkali solutions). Corrosion-resistant sensors effectively cope with medium erosion.
Wastewater Treatment and Environmental Protection Projects: Liquid level monitoring of sewage tanks, sewers, mud, and other easily polluted and adhesive media, reducing maintenance frequency.
Power and Metallurgy Industries: High-dust solid material level measurement in coal powder silos, ash hoppers, and slurry pools. Strong anti-interference ability ensures stable output.
Food, Pharmaceutical, and Water Treatment: Liquid level control of hygienic or corrosive media, supporting relay output for high and low level alarm interlocking.
System Integration Expansion: Seamless connection with DCS/PLC through 4-20mA or RS485 to achieve remote monitoring, data acquisition, and automated control.
In actual EPC projects and existing system renovations, the instrument significantly reduces installation difficulty and long-term operation and maintenance costs with its non-contact advantages and high protection performance.
Selection Guide and Integration Considerations
Correct selection can ensure long-term stable operation. It is recommended to refer to the following points:
Range and Blind Zone Matching: Select the appropriate range according to the container height and maximum material level, reserving sufficient blind zone (0.15-0.7m).
Medium Characteristic Analysis: For strong corrosive or adhesive media, prioritize PTFE sensors; for dust or foam conditions, evaluate the beam angle and installation position.
Output and Control Requirements: Use 4-20mA for basic monitoring; configure RS485 and relay output when remote communication or alarm interlocking is required.
Installation Environment: The cast aluminum enclosure is suitable for outdoor or explosion-proof areas. Ensure the probe is installed vertically downward during installation and avoid interference sources such as feed inlets and agitators.
System Integration Considerations:
Use standard terminals for wiring. It is recommended to use shielded cables to reduce the impact of electromagnetic interference on RS485 communication.
The temperature compensation function is built-in. It is still recommended to verify actual accuracy in extreme temperature difference environments.
When integrating with PLC/DCS, calibrate the 4-20mA output range and upper/lower limit alarm nodes.
Regularly check the cleanliness of the probe surface. For severely adhesive conditions, maintenance can be combined with a purging device.
For bulk projects, container dimensions, medium parameters, and control system interfaces can be provided in advance to achieve pre-configuration and testing.
