It primarily uses non-contact ultrasonic transducers for reliable and maintenance-free operation. In addition, it can input a secondary level gauge like a submersible pressure transducer or bubbler for redundant backup. I/O consists of six SPDT relays, seven digital inputs, 4-20 mA input and output with optional Modbus RTU or Profibus dP.
