EchoTREK ultrasonic level transmitters offer the best in solids level measurement in a compact simple package. Developed using the established SenSonic range of Narrow beam angle pulse echo transducers, EchoTREK level transmitter units are available with measurement ranges up to 60 meters. Installed on the tank roof, or above the surface to be measured, the level transmitter gives an analogue output proportional to the surface level. Initial set-up is achieved using the simple plug-in display module: then the intelligent QUEST+ process adaptive signal processing software system ensures that the electronics identifies and validates the surface level signal, giving reliable level monitoring.
