High Performance Ultrasonic Level Transmitter Non-Contact Liquid Level Sensor 4-20mA RS485 for Water Wastewater Tank Measurement

Product Description

The Ultrasonic Level Transmitter is a non-contact liquid level measurement device designed for continuous and accurate monitoring of tank liquid levels. It emits high-frequency ultrasonic pulses that reflect off the liquid surface and calculates the distance based on the echo return time. The transmitter converts this measurement into a standard 4-20mA analog signal or RS485 digital output for seamless integration with PLC, SCADA, or other industrial control systems.

Built with robust IP66/IP68-rated housing and advanced temperature compensation technology, this sensor delivers reliable performance in harsh industrial environments, including dusty, humid, or corrosive conditions. Whether you need to measure water, wastewater, fuel, oil, or chemicals, this ultrasonic level transmitter provides a cost-effective, maintenance-free solution for tank level monitoring and pump control.

Key Features

• Non-Contact Measurement: No direct contact with the liquid, preventing corrosion and contamination, ideal for corrosive or sticky media.

• Long Measuring Range: Available in ranges from 4m to 15m (customizable up to 20m), suitable for small sump pits to large storage tanks.

• Standard Signal Output: Supports 4-20mA (2-wire / 4-wire) and RS485 Modbus RTU output for easy integration with existing control systems.

• High Accuracy & Stability: Accuracy up to ±0.2% of full scale with built-in temperature compensation to eliminate measurement errors caused by ambient temperature changes.

• User-Friendly Configuration: Equipped with an LCD display and push-button interface for on-site parameter setting (range, blind zone, output mode, etc.). Optional Bluetooth module available for remote setup via smartphone.

• Adjustable Blind Zone: Minimum blind zone as low as 0.2m–0.5m depending on range, allowing measurement in shallow tanks or near the top of vessels.

• Durable Construction: IP68-rated aluminum or plastic housing with corrosion-resistant PVDF transducer, suitable for outdoor and harsh industrial environments.

• Smart Echo Processing: Advanced digital echo filtering algorithm effectively ignores false echoes from obstacles, stirrers, or tank walls.

• Explosion-Proof Option: Available with ATEX certification for use in hazardous areas such as oil refineries and chemical plants.

• Low Maintenance: No moving parts, ensuring long-term reliability and minimal operational costs.
