Ultrasonic Sensors for Level & Distance Measurement

BinMaster ToughSonic® ultrasonic sensors use non-contact ultrasonic sound waves to measure liquid levels and distances through the air. These rugged, compact sensors provide fast, reliable measurements up to 50 feet (15.2 meters) without contacting the material being measured.

 

ToughSonic sensors are used for liquid level monitoring, distance measurement, and object detection in industrial and environmental applications. They perform reliably in open or closed tanks, outdoor installations, and harsh processing environments.

 

Typical uses include inventory monitoring, batch control, high- and low-level alerts, flood monitoring, roll diameter measurement, object detection, and general industrial automation.

ToughSonic® Ultrasonic Sensor Features

Non-Contact Measurement

Non-Contact Measurement

Measure liquid levels and distances without touching the material, eliminating contamination risks and reducing sensor maintenance.

Precise Target Ranging

Precise Target Ranging

Sensors capture the exact distance to a target rather than simply detecting presence, allowing operators to monitor precise position/level.

Distance-Proportional Output

Distance-Proportional Output

The sensor output signal changes proportionally with measured distance for seamless integration with PLCs, controllers, and monitoring systems.

High-Resolution Measurement

High-Resolution Measurement

ToughSonic sensors detect very small changes in distance, making them ideal for applications requiring precise position or level measurement.

Immunity to Optical Conditions

Immunity to Optical Conditions

Ultrasonic sound wave technology is unaffected by ambient lighting conditions, object color, surface transparency, and reflectivity or shine.

Rugged Industrial Construction

Rugged Industrial Construction

Design offers a long service life in demanding environments: solid-state electronics, rugged transducers, and epoxy-potted components.


Ultrasonic sensors use ultrasonic sound waves that reflect and return to the sensor, which converts time-of-flight into a distance measurement

High-Frequency Technology

How ToughSonic® Ultrasonic Sensors Work

  1. The sensor emits an ultrasonic pulse toward the target surface.
  2. The sound wave reflects off the liquid surface or object.
  3. The sensor receives the returning echo.
  4. The time required for the signal to return is converted into a distance measurement.

Because the speed of sound in air is known, the sensor calculates the distance to the target surface with high accuracy.

The measured distance can then be used to determine liquid level in a tank, distance to an object, position of moving equipment, or diameter of a roll or coil.


ToughSonic® Mounting Options

Proper installation ensures reliable ultrasonic performance. ToughSonic sensors can be mounted above tanks, vessels, equipment, or open areas, depending on the application.

Top-of-Tank Mounting
Commonly used for liquid level measurement in tanks or vessels. The sensor is mounted above the liquid surface and aimed downward toward the target.

Bracket Mounting
Mounting brackets allow installation on structural frames, walls, or equipment for distance monitoring or object detection.

Open-Air Mounting
Sensors are mounted above the monitored surface to provide continuous distance measurement.

This includes environmental monitoring applications such as flood monitoring, water level monitoring, or reservoir and canal measurement.

Why Choose Ultrasonics?

Both ultrasonic and radar level sensors provide reliable non-contact measurement, but each technology performs best under different conditions.

Choose ultrasonic sensors when:

  • Measuring liquids in tanks, channels, or open environments
  • The application requires cost-effective non-contact measurement
  • Tanks are relatively short (typically under 50 feet)
  • The environment has minimal dust or foam
  • You need distance measurement or object detection

When Radar is Required

Choose radar sensors for applications where you're:

  • Measuring solids in dusty environments
  • Applications involve tall silos or vessels
  • There is heavy vapor, foam, or turbulence
  • Maximum measurement reliability is required in harsh process conditions

BinMaster offers multiple continuous level measurement technologies so customers can select the best solution for their application.

This includes 80 GHz radar transmitters, 3D level scanners, guided wave radar, laser, and SmartBob cable-based systems.


Selecting the Right ToughSonic® Ultrasonic Sensor

Choosing the correct ultrasonic sensor depends on the environment, installation conditions, and material being measured. Consider these factors:

Measurement Range

Measurement Range

Select a sensor capable of measuring the required distance. ToughSonic sensors measure up to 50 feet (15.2 meters).

Environmental Conditions

Environmental Conditions

Use TS-100 stainless-steel models for rugged industrial environments. Use TS-200 PVDF sensors for corrosive or chemical applications.

Mounting Location

Mounting Location

Sensors need clear line of sight to the surface/object. Avoid mounting near obstructions that may interfere with the ultrasonic signal.

Application Type

Application Type

There are best-suited ToughSonics for tank measurement, water monitoring, distance ranging, object detection, and industrial automation.
