The EchoTREK compact level transmitter for free flowing solids featuring narrow beam angle transducers is offered for solids level monitoring – where previously only more complex, two part systems have performed.
EchoTREK overcomes filling noise, dusting and irregular surface formations in most cases to give a high performance powder and solids level measurement. The optimal tilting position can be adjusted during operation, and it is 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.
