Honda Ultrasonic Level Sensor Meter

Introduction

HONDA ELECTRONICS has brought innovations to the world by introducing ultrasonic technologies since the release of the world-first transistor fishfinder in 1956. With originality in mind, HONDA ELECTRONICS also respects technologies in various fields and participates in many collaborative projects. This “Open Technology” policy shall lead us to make further contributions that will enhance human life.

Honda Ultrasonic Sensor are applying our ultrasonic research to a variety of fields within the industrial equipment sector.
Cleaners(Ultrasonic washers), machining tools(ultrasonic welders), measuring equipment, flow meter, and so forth, have proven their use under various conditions. And new applications in the areas of ultrasonic reactor(maturity)and power dynamics(motors) hold great promise for future success.

Our Industrial Instruments Division works with over 500 ultrasonic elemental technologies to develop and market state-of-the-art products. And in joint research with clients in a variety of fields, we are furthering our goals by designing the industrial instruments of tomorrow.

Principle

Ultrasonic waves transmitted from the sensor are reflected back from the measured object, and the distance is calculated based on
the echo return time. This makes it possible to perform operations such as measuring the liquid level inside a tank, or monitoring the
remaining amount of materials in a tank.

  • Distance = Speed of sound × Time

The distance to the measured surface is calculated based on the speed of sound and the time elapsed between the transmission of
the signal and the return of the echo. The distance to the bottom of the tank is set in advance, so that the amount of liquid remaining
in the tank can be calculated.

Advantages

Levels can be monitored without any contact with the materials that are measured. Levels can be monitored continuously, even under HD duty conditions.

5. HL2000 | Ultrasonic Interface Level Meter

Overview

Measures the flying time of ultrasonic signal to the sludge level. Ultrasonic signal has characteristic that it reflects where the density changes. Submerged sensor transmit ultrasonic signal, then the signal reflects at the interface inside the tank. Some part of signal penetrate into the sludge and it also reflects at the rake or bottom of the tank. Ultrasonic signal transfers in the unclear water. There is no need to contact to the measuring object (sludge), the measurement can be done without sinking the sensor deep into the tank.
