Emerson Rosemount 1208 Level and Flow Transmitter Series

Emerson has introduced the Rosemount 1208 Level and Flow Transmitter Series non-contacting radar transmitters. The product is an alternative to ultrasonic and hydrostatic devices for water monitoring applications, featuring 80 GHz fast-sweep frequency modulated continuous wave (FMCW) technology on a single electronic chip, which delivers measurements within a compact device suitable for applications with space constraints or compliance requirements, such as water applications.

The measurement accuracy of the line is unaffected by most process conditions, including condensation and variations in pressure, temperature and density. The transmitter collects information with fast-sweep FMCW technology and advanced algorithms. This provides level measurement accuracy of 2 mm at a range of 15 m, helping organisations optimise processes and comply with environmental requirements. In addition, the non-contacting design has no moving parts or calibration requirements, creating a virtually maintenance-free device that minimises manual procedures and delivers long-term performance.

The transmitter is available in two models, offering different communication protocols and approvals. It is designed specifically for water and process industry utility applications and offers IO-Link connectivity as part of its hybrid communication options that also include three-wire 4–20 mA and switch outputs. IO-Link connectivity reduces installation complexity, enables simple integration into high-level automation networks and provides access to process insights that can enhance operational performance. It further reduces complexity by enabling remote configuration and monitoring.

The product offers two-wire 4–20 mA and HART communication options, providing access to advanced diagnostics. This supports predictive maintenance and more effective troubleshooting, leading to reduced downtime and improved operational efficiency. Hazardous area approval enables use in areas where an explosive gas atmosphere could occur during normal operation.
