Emerson Rosemount 1208 level and flow transmitter series

Emerson has introduced the Rosemount 1208 level and flow transmitter series. The non-contacting radar transmitters are designed to help increase the operational efficiency of water, wastewater and process industry utility applications.

Operators in the water and wastewater, food and beverage, chemical and other process industries often deploy ultrasonic and hydrostatic devices for water monitoring applications when radar transmitters are considered too expensive, bulky or complex. The Rosemount 1208 is an alternative, featuring 80 GHz fast-sweep frequency modulated continuous wave (FMCW) technology on a single electronic chip, which delivers measurement within a compact and more cost-effective device suitable for applications with space constraints or compliance requirements, such as water applications.

The measurement accuracy of the Rosemount 1208 is unaffected by most process conditions, including condensation and variations in pressure, temperature and density. By using fast-sweep FMCW technology and internal algorithms, the transmitter can achieve a level measurement accuracy of ±2 mm at a range of 15 m. In addition, the non-contacting design has no moving parts or calibration requirements, creating a virtually maintenance-free device that minimises manual procedures.

The transmitter is available in two models, offering different communication protocols and approvals. The Rosemount 1208A offers IO-Link connectivity as part of its hybrid communication options that also include three-wire 4–20 mA and switch outputs.

The Rosemount 1208C offers two-wire 4–20 mA and HART communication options, providing access to advanced diagnostics. Hazardous area approval enables use in areas where an explosive gas atmosphere could occur during normal operation.
