The NUS series ultrasonic level transmitter is the ideal choice for continuous non- contact level measurement in liquids or coarse grained, or pelletized solids. This non-contact level measurement technique allows reliable measurement of dirty, viscous, and coating medium. The NUS series boasts an extremely narrow beam cone allowing for measurements in tall tanks while minimizing the chances of problems due to obstructions in the tank. The NUS comes in DC powered 2-wire transmitter or an AC powered 4-wire transmitter version. A front panel mounted LED level indicator is standard.
