Ultrasonic Level Sensor

The SmartSonic ultrasonic level sensor is designed for continuous non-contact level measurement in liquids. The sensors are used to monitor levels in storage tanks and open basins or containers. Its transmitter features a high efficiency, narrow beam and uses a wide frequency bandwidth to enhance operation in difficult applications. SmartSonic liquid level sensors perform particularly well in harsh environments where vessel temperatures vary, using a temperature sensor to automatically compensate for temperature changes. Its transmitter range allows for level readings from 0.4 to 60 feet in water tanks and other liquid applications.

How Ultrasonic Works

This distance sensor transmits ultrasonic pulses from a transducer to the surface of a liquid. They emit sound above the human hearing range to detect echoes off a material surface and convert it to a distance using “time of flight.” Smart signal processing eliminates unwanted echoes to ensure accuracy. They offer built-in temperature compensation and self-cleaning operation in liquids up to 60 feet.

Sensor Mounting

BinMaster’s ball & socket mounting flange is ideal when the sensor is mounted on a rounded, domed, or angled rooftop. This optional self-aligning, carbon steel, 3” swiveling flange provides a vertical connection and enables easy aiming flexibility to reduce the risk of false echoes.
