Ultrasonic Level Transmitters3

Ultrasonic Level Indicator, also called Ultrasonic level sensor, or ultrasonic level transmitter.

Ultrasonic Level Transmitter provides reliable, accurate, non-contact measurement of liquid levels.

Ultrasonic non-contact technology offers no moving parts to wear, jam, corrode or get coated like contact technologies.

Mapping software makes an effective measuring surface only a 3″ diameter column.

No concerns with ladders, pipes, or other tank intrusions in the remaining sound cone.

Unit is FM approved explosion-proof making it ideal for use in hazardous locations.

ULT-100 ultrasonic level gauge is a high-frequency pulse sound wave,

generated by the transducer (probe),

is reflected back to the measured material (liquid, solid) surface,

and the reflected echo is received and converted into an electrical signal,

by the same transducer.

This signal is controlled remotely by A microprocessor program.

It can display many typical modes so that the level gauge can adapt to various complex working conditions,

such as solid, liquid, dust and so on.

What is the principle of ultrasonic level measurement?

Ultrasonic waves detect an object in the same way as Radar does it.

Ultrasonic uses sound waves, and Radar uses radio waves.

When the ultrasonic pulse signal is targeted towards an object,

it is reflected by the object and echo returns to the sender.

The time traveled by the ultrasonic pulse is calculated,

and the distance of the object is found.

Bats use a well-known method to measure the distance while traveling.

The ultrasonic level measurement principle is also used to find out fish positions in the ocean,

locate submarines below water level, also the position of a scuba diver in the sea.

We will refer to Fig-1,

and make an effort to understand the technicalities of the ultrasonic level transmitter.

An ultrasonic level transmitter is fixed at the top of a tank half-filled with liquid.

The reference level for all measurements is the bottom of the tank.

Level to be detected is marked as “C”, and “B” is the distance of the ultrasonic sensor from the liquid level.

Ultrasonic pulse signals are transmitted from the transmitter,

and it is reflected back to the sensor.

Travel time of the ultrasonic pulse from the sensor to target and back is calculated.

Level “C” can be found by multiplying half of this time with the speed of sound in air.

The measuring unit final result can be centimeters, feet, inches, etc.

Level = Speed of sound in air x Time delay / 2
