The Siemens SITRANS LUT400 series controllers are compact, single point, long-range ultrasonic controllers for continuous level, or volume measurement of liquids, slurries, and solids, and high accuracy monitoring of open channel flow.
| Range | 0.3 … 60 m (1 … 196 ft), transducer dependent |
| Compatible transducers | All EchoMax and ST-H series transducers |
| Accuracy | – Standard operation: ± 1 mm (0.04 inch) plus 0.17 % of measured distance – High accuracy OCM: ± 1 mm (0.04 inch), within 3 m (9.84 ft) range |
