The Working Principle of Ultrasonic Level Sensor. The objects shake, which lets people listen, whose frequency is between 20HZ and 20KHZ. Ultrasonic wave is more than 20KHZ, infrasonic

The measuring principle of hydrostatic level sensors operates on pressure measurement, i.e. the pressure at the container bottom is detected by the measuring cell of the pressure transmitter for calculation of the related filling level. With rising filling level, hydrostatic pressure increases by gravity. Product portfolio: Hydrostatic level

Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high frequency (20 kHz to 200 kHz) acoustic waves that are reflected back to and detected by the emitting transducer.

26/07/  · The ultrasonic liquid level sensor is a non-contact measuring device. That can send and receive high-frequency sound waves to measure the distance to the surface of liquid-based materials. The ultrasonic liquid level measurement uses the non-contact principle. It is most suitable for level measurement of hot, corrosive, and boiling liquids.

21/03/  · Ultrasonic Level Sensor Working Principle: This water level controller will use two components the ultrasonic sensor and relay board. The distance for the motor to turn off and on needs to be specified. There is a special program that executes the sensor. There are a lot of capacitors, circuit boards, resistors, and semiconductors used.

An ultrasonic sensor emits a sound pulse in the ultrasonic range. This sound pulse propagates at the speed of sound through air (about 344 meters per second) until the sound pulse encounters an object. The sound pulse bounces off the object and is returned in reverse to the sensor where this "echo" is received.

The ultrasonic sensor communicates with LVCN414‐SW software through a USB® interface called a Fob. Before plugging your Fob into your computer's USB® port, be sure that you have installed the LVCN414‐SW software on your computer. Connect the red, green, white and black wires from sensor into the correct terminals on the Fob.

For example Radar level measurement is great choice for accuracy but very expensive. On the other hand, Ultrasonic level sensors cost less and are easy to install and use, making them the most popular non-contact method for level measurement. Ultrasonic Level Sensor's Working Principle. Ultrasonic level sensors use the Time-of-Flight measuring
