Operating principles of ultrasonic wave level meters and application examples

Our ultrasonic level meters are used in various locations as a non contact type level meter.
This page introduces the operating principles of ultrasonic wave level meters and shows some application examples. If you are saying, We need a level sensor that can measure in our specific conditions, then count on us. We can provide devices that will meet any need, including the following.

Operating principles of ultrasonic wave level meter

Please think of how an echo in mountains works.
If you make a large sound toward mountains at a distance, your voice will be reflected and return after a delay.
A sensor oscillator generates ultrasonic pulse waves. By measuring time to return the waves after reflected on the material to be measured (liquid etc.), the meter continuously output liquid level. Namely, if the distance between the level meter and material is short, the time to return waves is shorter. If the distance between the level meter and material is long, the time to return waves is longer. The wave return time changes according to the rise and fall of the liquid level. The meter converts these return times to a level signal.

Advantages of ultrasonic wave type level meter

• This level meter can measure various substances without contact.
• It can also measure slurry and corrosive liquids.

Application example・Ultrasonic wave level sensors can be easily tuned locally

We are using a ultrasonic wave level meter. However, settings to measure is troublesome compared with other level meters with another principles. The currently used meter is required to repeat turning by connecting a PC.
Is there a ultrasonic wave level meter that can be operated and measured easily?

A. Ultrasonic wave level meters are the mostly often used level meters among non-contact types. However, they have problems to difficult to set and tune locally. Especially, initial setting before start measurement and tuning to match material are difficult and manufacturer's engineer visit locally and set these using a PC.
This time we would like to introduce a ultrasonic wave level meter that can easily be used by user.

We recommend this level meter to those who have not been able to use an ultrasonic wave level meter effectively before.

• A large size LCD display shows level indication screen, trend screen, and eco graph screen. These screens are useful for eco process and signal process. Needless to say, you do not need to connect it to a PC.
• The system has minimum required functions for settings, so users can set it by themselves.
  You can set eco-process while looking at the LCD screen.
• Lower price than the conventional models. As it has multi-amplifier function, you can measure two positions with one unit.

Renting a demonstration mode is available. Please free to contact our sales staff.

Application example・Detect objects on a belt conveyor

Is it possible to detect the presence of objects fed onto a belt conveyor easily and at low cost?

A. Level meters for tanks (hoppers) and silos are popular. A steel manufacturer is using an ultrasonic wave level sensor for detecting objects (ore) fed onto a belt conveyor.
Using low price ultrasonic wave sensors, it allows to detect objects on a conveyor and solved the problem.Use of this case to another material and conditions are also possible.
