Rosemount™ 1208 Level and Flow Transmitter - Non-Contacting Radar
The Rosemount 1208 Series provides accurate and reliable level measurement and open channel flow calculations.
The radar level transmitter has been designed to solve challenges in water and wastewater-, utilities- and basic chemical applications. The Rosemount 1208 uses continuous non-contacting radar technology in a compact PVDF housing with drinking water and food grade approvals. Its encapsulated design withstands outdoor conditions, is fully submersible and is suitable for hazardous location installations. The Rosemount 1208 Series communicates via Bluetooth® wireless technology, 4-20 mA HART™ or IO-link and has a broad range of mounting accessories, making it easily integrate into both new as well as existing systems.
