SLDL2110 Ultrasonic Level Indicator
The SLDL2110 Ultrasonic Level Indicator is a high-precision, non-contact level measurement device designed for reliable monitoring in tanks and vessels across industrial applications. Built with advanced ultrasonic technology and patented signal processing, this level indicator delivers stable, real-time data while adapting to harsh environments, corrosive media, and complex working conditions. As a flagship product from Solidat Applied Technologies Ltd., the SLDL2110 Ultrasonic Level Indicator combines ease of use, durability, and professional performance to support efficient process control and inventory management.
Working Principle of SLDL2110 Ultrasonic Level Indicator
The SLDL2110 Ultrasonic Level Indicator operates by transmitting ultrasonic pulses that reflect off the surface of the measured medium. The sensor receives the echo and converts it into an electrical signal. The distance between the sensor and the medium is calculated using the formula S=C×T/2, where S is distance, C is sound velocity, and T is the time interval of pulse transmission and reception. This non-contact principle ensures the SLDL2110 Ultrasonic Level Indicator remains unaffected by medium conductivity, viscosity, or contamination, making it suitable for almost all liquid types.
Key Features of SLDL2110 Ultrasonic Level Indicator
The SLDL2110 Ultrasonic Level Indicator adopts patented acoustic wave matching technology to enhance signal stability and measurement accuracy. It supports debug-free and calibration-free operation, reducing on-site workload and improving efficiency. A built-in temperature sensor provides intelligent compensation to maintain precision under changing environmental conditions.
The SLDL2110 Ultrasonic Level Indicator includes one-click false echo learning, which filters interference from tank walls, fixtures, and condensation to ensure accurate readings. A false echo display function assists engineers in analyzing on-site conditions for faster commissioning. The device supports multiple languages including Chinese menus, and accepts external 4–20mA input for multi-sensor fusion. It also integrates GPS input to transmit location and measurement data simultaneously.
Communication Protocols Supported by SLDL2110 Ultrasonic Level Indicator
The SLDL2110 Ultrasonic Level Indicator offers extensive connectivity for industrial systems:
•HART
• Modbus
• Profibus PA
• Foundation Fieldbus
• GPRS/CDMA remote transmission
• Bluetooth
This wide protocol support makes the SLDL2110 Ultrasonic Level Indicator compatible with PLC, DCS, SCADA, and cloud platforms for remote monitoring and data managem
Installation Guidelines for SLDL2110 Ultrasonic Level Indicator
Correct installation improves the long-term stability of the SLDL2110 Ultrasonic Level Indicator. Cables should be routed downward before connection to prevent moisture ingress, especially in outdoor or high-humidity environments. The sensor should be mounted vertically for optimal performance. In asymmetric tanks such as horizontal cylinders or spherical vessels, a sealing tube or signal linearization is recommended. For condensation-prone conditions, a shielded or extended insulating tube helps avoid measurement errors caused by moisture bridges.
Applications of SLDL2110 Ultrasonic Level Indicator
The SLDL2110 Ultrasonic Level Indicator serves many industries:
• Water and wastewater treatment
• Chemical storage and processing
• Food and beverage production
• Oil and gas tank monitoring
• Industrial inventory control
• Tank filling and emptying systems
Its non-contact design allows the SLDL2110 Ultrasonic Level Indicator to safely measure corrosive, abrasive, opaque, and high-temperature liquids without contact or contamination risk.
