Description

The 4-wire EasyTREK & EchoTREK compact ultrasonic level transmitters are offered for solids level monitoring tasks where previously only more complex, two-part systems have performed adequately. NIVELCO’s high-efficiency SenSonic narrow beam angle transducers, giving superb signal transmission, make it possible that the EasyTREK & EchoTREK units overcome filling noise, dusting, and irregular surface formations in most cases to give high performance, compact, powder and solids level measurement transmitter. This is provided by the QUEST+ software, using advanced process adaptive signal processing for reliable echo monitoring, offering a best-in-class solution.

APPLICATIONS:

  • Measurement of normal and explosive dust hazardous powders and bulk solids
  • Level, volume, and weight calculation
  • Wide application range: light powders to coarse bulk solid materials
  • Reliable measurement in challenging applications such as dusting during filling

OPERATION:

Ultrasonic level metering technology is based on the principle of measuring the time required for the ultrasound pulses to cover the distance from the sensor to the surface of the medium and back. The echoes bounced back from the surface reach the face of the sensor after the time of flight of the ultrasonic impulse. The time of flight of the reflected signal is measured and processed by the electronics, and then this is converted to distance, level, volume, or mass proportional data with the help of the customizable tank shape and dimensions. The intelligent QUEST+ process adaptive signal processing software system ensures that the electronics identifies and validates the solids surface signal, giving reliable level monitoring.

Coning or arching caused by the filling/emptying process can result in an adversely weak echo when the transducer is installed vertically. The joystick aiming device, an important part of the EasyTREK & EchoTREK level transmitters offers a suitable solution to minimize most of these unfavorable effects. The optimal tilting position can be adjusted during operation and recommended to be checked at multiple levels during the filling/emptying process. As a general rule, the best result is obtained by the transducer aimed towards the center of the tank bottom.
