The users of ultrasonic liquid level indicator will be aware of the minor limitations of this level sensor that sometimes, under certain circumstances, may not be able to give correct liquid level readings. This does not come under the product’s flaws; rather it is related to the way ultrasonic waves works.

To fully utilize this level sensor, you must first thoroughly understand how this device works. This device works with ultrasonic sound waves that travel from transducer to the liquid surface and emit back to the transducer, which than calculates their time and distance to measure the exact liquid level inside containers, vessels or pipelines.

Factors like surface turbulence, gas bubbles, rise and fall in temperature, steam and other minor obstacles inside the vessel can greatly affect the movements of ultrasonic sound waves, which can result in incorrect readings via ... Read more »
