EasyTREK / EchoTREK Ultrasonic Level Transmitter
Brand: Nivelco Process Control Co.The 4-wire EasyTREK and 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 possible that the EasyTREK and EchoTREK units overcome filling noise, dusting and irregular surface formations in most cases to give a high performance, compact, powder and solids level measurement transmitter.
This is provided by the QUESTplus software, using advanced process adaptive signal processing for reliable echo monitoring, offering a best-in-class solution.
