Instruments de mesure de niveau
Capteur de niveau à ultrasons
The ultrasonic level gauge is a non-contact, high-reliability, and cost-effective device for accurate ultrasonic level measurement of liquids, slurries, and solids in industrial environments. Designed for easy installation and low maintenance, it offers a reliable solution for water treatment, municipal, chemical, metallurgical, and machinery manufacturing applications.
Ultrasonic level sensors are available in two types: integrated and separated. The integrated type combines the sensor and host into a single unit, providing simple and convenient installation. The separated type allows the sensor and host to be installed independently, making it ideal for storage tanks, silos, and bracket-mounted setups.

Level Ultrasonic Sensor-Common Applications
Water Tanks: Ultrasonic water level sensors provide accurate, real-time monitoring for residential, commercial, and industrial tanks, preventing overflow or shortages.
Industrial Processes: Used in chemical, food & beverage, pharmaceutical, and wastewater treatment industries to maintain precise ultrasonic level measurement in tanks and vessels.
Pump Control: Can integrate with pump systems for automatic water level management in irrigation, sewage, and drainage systems.
Environmental Monitoring: Ideal for rivers, lakes, and reservoirs, enabling ultrasonic water level detection for flood forecasting and water resource management.
Hydroelectric Power Plants: Monitors reservoir levels to regulate turbine flow, ensuring safe and efficient power generation.
Aquaculture: Maintains optimal water levels in ponds, tanks, and raceways, supporting healthy growth of aquatic species.
Swimming Pools and Spas: Ensures water levels remain within safe and comfortable ranges to prevent overfilling or draining.
Ultrasonic Water Level Sensor-Working Principle
Le ultrasonic level sensor measures liquid levels using non-contact ultrasonic technology. It works in four main steps:
Ultrasonic Emission: The sensor emits ultrasonic pulses, typically in the frequency range of 20 kHz to 200 kHz.
Propagation: The pulses travel through air or other media until they encounter the liquid surface. Part of the energy reflects back while the remainder continues downward.
Reflection and Reception: The sensor’s receiver captures the reflected ultrasonic waves. The time delay between emission and reception corresponds to the travel time of the pulses.
Level Calculation: By calculating the propagation time, the sensor determines the distance from the liquid surface to the sensor, which directly indicates the liquid level.
This non-contact ultrasonic measurement ensures accurate and reliable monitoring in tanks, reservoirs, silos, and other industrial applications, making it ideal for ultrasonic water level detection and ultrasonic level measurement.
Ultrasonic Tank Level Sensor-Structure
Le ultrasonic level sensor is available in two types: integrated (one-piece) type and separated (two-piece) type, designed for flexible installation and diverse industrial applications.
Integrated Type:
The sensor and host are combined into a single unit.
Simplifies installation and wiring.
Ideal for compact tanks or vessels where space is limited.
Separated Type:
The sensor probe is installed separately from the host unit.
Suitable for large storage tanks, silos, or bracket-mounted installations.
Allows easier maintenance and flexible positioning for optimal signal reception.
Key Components:
Sensor Probe: Stainless steel or PVDF, corrosion-resistant.
Electronics Housing: IP67 protection, dustproof and waterproof.
Display/Control Module: Optional LCD/LED interface for local readings.
Connection Interface: Standard cable or M12 connector for signal transmission.
This design ensures accurate ultrasonic level measurement and reliable performance in diverse industrial environments.
