EchoTREK for Liquids

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 and EchoTREK level transmitters offers a suitable solution to minimize most of the 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, best result is obtained by the transducer aimed towards the center of the tank bottom.
