The SmartScan2525 Long Range Ultrasonic Level Sensor is a professional two-part non-contact measurement device designed for long-distance level monitoring in large‑scale industrial and outdoor applications. This high‑performance sensor delivers stable and accurate readings even in demanding environments, making it the ideal choice for projects requiring extended measuring ranges and reliable operation. With its robust design and flexible configuration, the SmartScan2525 Long Range Ultrasonic Level Sensor supports both liquid and solid materials, covering a wide spectrum of uses from water management to heavy industry and agricultural storage.
The SmartScan2525 Long Range Ultrasonic Level Sensor is widely used in scenarios that demand long‑distance and high‑reliability detection. Typical applications include water reservoirs, rivers, waterways, dams, and large‑capacity storage tanks, where long-range measurement is essential. It also serves the chemical, food, agricultural, and heavy industries, providing stable level data for various process and storage vessels.
This SmartScan2525 Long Range Ultrasonic Level Sensor can reliably measure liquids as well as bulk solids such as grains, poultry feed, and other industrial particles. It is certified for use in hazardous (explosive) atmospheres, making it suitable for oil, gas, and chemical facilities where safety standards are strict. For large storage vessels, high process tanks, and open‑air stock piles, the SmartScan2525 Long Range Ultrasonic Level Sensor offers a durable and cost-effective level monitoring solution.



The SmartScan2525 Long Range Ultrasonic Level Sensor adopts a 4‑wire non‑contact structure to ensure continuous and stable measurement. The standard version reaches up to 25 meters for liquids, while the extended range version supports up to 40 meters. For solid materials, the maximum detection distance is 30 meters, satisfying most long‑range level monitoring needs.
A major advantage of the SmartScan2525 Long Range Ultrasonic Level Sensor is its split design, which allows the control unit to be installed up to 200 meters away from the sensing probe. This greatly improves installation flexibility and on-site safety. The device supports multiple output interfaces including analog 4‑20mA, RS232, RS485, and Modbus read protocol, and is equipped with a large display for easy on‑site operation and monitoring. It also includes 5 independent SPDT relays that can be programmed for automatic control, alarm triggering, and pump management.
The SmartScan2525 Long Range Ultrasonic Level Sensor provides users with a choice between polypropylene or PVDF sensor materials to suit different media and corrosion resistance requirements. An optional intrinsically safe, Ex‑certified model is available for use in explosive hazardous environments.
The operating temperature range spans from ‑40°C to 80°C, enabling stable performance in extreme cold and hot environments. The SmartScan2525 Long Range Ultrasonic Level Sensor requires no on‑site calibration and minimal maintenance, reducing long‑term operating costs. It integrates advanced intelligent algorithms including automatic temperature compensation, false echo extraction, and gas factor compensation to ensure high accuracy under complex working conditions.
For enterprises seeking a long‑distance, high‑reliability level sensing solution, the SmartScan2525 Long Range Ultrasonic Level Sensor combines extended measuring range, flexible installation, rich communication interfaces, and strong environmental adaptability. It is widely trusted in water conservancy, chemical, agricultural, and heavy industrial applications, and supports customized solutions to meet specific project requirements. Solidat Applied Technologies Ltd., as a leading manufacturer, provides high‑quality products, competitive pricing, and professional after‑sales support to global customers.
