Ultrasonic Level Transmitter

Non Contact Ultrasonic Level Transmitter consist of a family of Ultrasonic with a frequency range in KHz. The offered Ultrasonics are available in different configuration and process connections as per customer requirement. Ultrasonic Level Transmitters provide a cost effective and reliable solution for level measurement for non aggressive liquids and slurry applications

The ultrasonic impulses generated from transducers “antenna system”,which travel at the speed of sound, come reflected by the surface of medium and newly sent back to the transducer. 

The period of time that passes between the emission of impulses and the reception of the same ones from the antenna, is proportional to the existing distance between the same antenna and the higher level of the medium to measure, therefore the principle of the ultrasonic measure can be illustrated with the following equation: 


where S: distance, C: velocity of sound, T: time lapse 

Because of the wide band impulses, the overlap between the emission and the reception of the same impulses increases in particular zones, extending itself from the transducer to the bottom, causing a wrong measurement of the level. This error zone is defined “blanking zones” and its dimension vary based on the various models of ultrasonic meters that are used. 

The use of an advanced microprocessor and the technology “EchoDiscovery”, allows the user of the instrument also in critical zones with heavy jobs. The function “False echo storage” assures the device to identify the correct echo also in presence of false ECHO, supplying correct measures. The integrated temperature sensor puts into effect a temperature compensation in real time.
