Ultrasonic Level Sensors for Distance Measurement

Massa is a leading innovator and pioneer in the field of industrial ultrasonic sensor manufacturing for use in air, chemicals, and water. MassaSonic® sensors areideal for measuring fluids, pastes, solid bulk materials, or mechanical structures, for ranges from 1 inch (25 mm) to 20 feet (6 m). They are also unaffected by color, transparency, or material of the target, unlike other competing technologies.
