Compact Ultrasonic Level Sensor

Ideal for single tank applications that may only require one or two ultrasonic sensors. As with other ultrasonic level sensors, the SONO-1000 measures the time required for ultrasound pulses to make a round trip from the sensor to the material and back.

Measuring with Precision

With a narrow beam angle of 5 degrees, the SONO-1000 ultrasonic level senor is able to focus on a specific point within the vessel to determine the level; it has a maximum measuring distance of 98 ft (30 m).

Technology: Ultrasonics
Applications: Single vessel, non-contact solution for dry bulk solids

More Features

Ideal for filling and emptying bins and for accurate inventory management

Used with free flowing solids, display level, volume or weight calculations and achieve reliable, non-contact measurement of dry bulk solids.
