Ultrasonic Transmitters, Sensors and Transducers
Ideal for Liquid Level Control

MassaSonic Logo

Massa develops and produces ultrasonic transmitters, sensors and transducers for use in air and in fluids for process and liquid level control.  In our 70 year history we have designed hundreds of different sensors for use in a wide variety of industrial/commercial applications, including liquid level control, bulk level monitoring, non-contact distance measurement, web break detection and tensioning, Doppler motion detection, collision avoidance, and more.  Massa has the fundamental U.S. Patents on virtually every type of air ultrasonic (and submersible sonar) that exist in today’s markets.  Our patent portfolio contains basic concepts for Tonpilz type resonators used for seafloor mapping and sub-bottom profiling, as well as the new cutting-edge ultrasonic fan-shaped beam technology.  Some of these products are offered as standard products, while other technologies that Massa holds as proprietary are often encompassed in our bespoke designs for customers.

Our new lines of MassaSonic® Sensors are compatible with our Legacy Sensors, and include PulStar® Series Sensors (which replace Legacy M-300 and M-320 Sensors), SonAire® Series Sensors (which replace Legacy M3 and M3is Sensors), mPulse® Series Sensors (which replace Legacy M-5000 Sensors), and the all new FlatPack® Series Sensors.  The SonAire Model M3is Sensor is certified to the highest level of intrinsic safety – Hazardous Location C1 D1, All Groups.

Massa also manufactures two standard lines of transducers.  One line consists of Ultrasonic Transducers for operation in air, and the other contains underwater transducers for use by the Oceanographic community.

We also offer custom designed ultrasonic transmitters, measurement sensors, and transducers for OEM and private label partners.  Massa has the unique capability to customize an ultrasonic or oceanographic design to meet your exact requirements.  Most of the time the solution only requires a slight modification of the hundreds of designs we have previously developed.  We can then provide high volume, low cost, reliable production.  Contact an Application Specialist to discuss your specific ultrasonic measurement needs.

For more information regarding how to evaluate both the acoustics of the environment around a sensor and the different acoustical properties of a sensor or ultrasonic transducer in order to optimize the system’s operation in your application, view “Choosing an Ultrasonic Sensor for Proximity or Distance Measurement” by clicking Part 1: Acoustic Considerations, and Part 2: Optimizing Sensor Selections.  You can also obtain more information on our Fundamentals page.



As a family company, Massa Products Corporation places the highest emphasis upon quality in all we do,
where it begins not as a 
statement, but as a value.  Quality is our policy; this is the case from the earliest stages
of our designs, through the final production of our products, 
and most importantly with the relationships
we nurture with our customers, and vendors – it is evident that with Massa you’re family.
