The DS1603 Ultrasonic Liquid Level Sensor, designed and manufactured by Shenzhen Xingkechuang Co., Ltd., represents a breakthrough in non-invasive liquid level measurement technology. Utilizing advanced ultrasonic penetration technology, this sensor enables accurate detection of liquid levels inside sealed containers without direct contact with the liquid itself. This innovative approach makes it ideal for measuring hazardous, corrosive, or sterile liquids where traditional contact sensors would be impractical or unsafe.
Our factory-direct sales model ensures competitive pricing, complete specification availability, and comprehensive customization options to meet the unique requirements of industrial and commercial applications worldwide. The DS1603 series has been rigorously tested and proven reliable in demanding environments across multiple industries.
The DS1603 sensor operates on the principle of ultrasonic wave propagation. It emits high-frequency ultrasonic waves (2 MHz) that penetrate through the container wall and reflect off the liquid surface. The sensor then measures the time it takes for the reflected waves to return, calculating the precise liquid level based on this time-of-flight measurement.
This non-contact method eliminates the risk of contamination, corrosion, or leakage associated with traditional immersion sensors. It also allows for installation on the outside of existing containers, eliminating the need for costly modifications or process shutdowns during installation.
The DS1603 sensor's non-contact design makes it perfect for measuring toxic substances, strong acids, strong alkalis, and other hazardous liquids. It can operate safely in high-temperature and high-pressure airtight containers where direct contact would be dangerous or impossible. This feature significantly reduces maintenance costs and improves workplace safety.
With a blind zone of only ≤50 mm and real-time liquid height output, the DS1603 provides accurate and up-to-date level measurements. The sensor has a 1-second work cycle, ensuring that you always have the most current information about your liquid levels. This precision is critical for process control, inventory management, and preventing overflows or dry runs.
The DS1603 sensor can detect liquid levels through both metal and non-metal containers of various materials and thicknesses. It is compatible with insulating liquids such as gasoline and diesel, as well as water and other conductive liquids. The sensor works with container widths ranging from 50 mm to 2000 mm, making it suitable for a wide range of tank sizes.
The compact size of the DS1603 sensor (27.7 mm × 17 mm × 450 mm) allows for easy installation in tight spaces. It features strong anti-interference capabilities and reliable performance even in noisy industrial environments. The sensor complies with the IEC61000-4-2 ESD standard (±4/±8 KV), ensuring protection against electrostatic discharge.
The DS1603 Ultrasonic Liquid Level Sensor is suitable for real-time detection of various liquids, especially those that are difficult to access. It has been widely used in:
Beverage production and processing
Household appliances manufacturing
Medical equipment and healthcare facilities
Drinking water treatment and distribution systems
Chemical processing and manufacturing
Industrial automation and process control
Hazardous liquid storage and handling
The DS1603 sensor can detect a wide range of liquids, including water, gasoline, diesel, various chemicals, strong acids, strong alkalis, and toxic substances. It is particularly effective with insulating liquids but also works well with many conductive liquids.
Yes, the DS1603 sensor is designed to penetrate both metal and non-metal containers. It has been tested and proven effective on 5mm thick steel plate containers at room temperature.
The standard DS1603NF model is optimized for containers up to 5mm thick. For thicker containers or special materials, we offer customized solutions to meet your specific requirements.
The sensor is designed for easy external installation on the bottom or side of the container. No drilling or modification of the container is required. Simply mount the sensor using adhesive or mechanical fasteners, connect the power and output wires, and calibrate according to the user manual.
At Shenzhen Xingkechuang, we understand that every application is unique. That's why we offer comprehensive customization options for the DS1603 series, including different output signals (UART serial port, RS485 communication, voltage analog value), custom cable lengths, and specialized probes for extreme environments.
