Portable Ultrasonic Liquid Level Sensor Transmitter

Handheld measurement of liquid level indicator in a closed container

SKE portable level transmitter is designed to offer a simple, accurate, rapid, and reliable method of Liquid level measurement. When the magnetic probe is bonded to the bottom shell of the tank, an ultrasonic sound wave travels through the tank and reflects back from the media surface. The system calculates the height of the liquid, from the time taken for the signal to be received. It features a truly non-invasive sensing technique.

Principle

The ultrasonic wave signal is emitted from the probe sensor, and the echo signal is detected after being reflected form the liquid surface.
The signal is processed by the SKE algorithm then calculate the time “t”, and the system calculates the liquid level according to the formula:

H: The height of the liquid level
t: The time taken by the sonar wave from launch to return
tg: The transmission time of the ultrasonic wave in the tank wall
v: The speed of ultrasonic wave propagating in liquid
α: Correction factor

Application area

For tanks

The probe is mounted directly below the vessel.
Tank wall without lining or gas interlayer.
there is no solid obstruction (such as coils, partitions, leaky plates, etc.) between directly above the probe and the liquid surface.
The tank wall is made of hard materials, such as various hard metals, glass fiber reinforced plastics, hard plastics, hard rubber, etc.
For medium

The dynamic viscosity of the tested liquid is less than 10mPa·S
The liquid has no large amount of precipitation and crystallization, and no dense bubbles inside
