Universal software package suitable for almost all liquid applications

The Rosemount 2120 is based on vibration short fork technology and is suitable for almost all liquid applications. It has a complete range of process connectors, multiple optional materials for shells and liquid receiving parts, four different switch functions, tuning fork length extension options, hazardous area certification, basic self checking function, and anti overflow certification. The 2120 can withstand temperatures up to 302 ° F (150 ° C) and pressures up to 1450 PSI (100 bar g). These functions combined make it possible to meet almost all requirements through configuration.

Operation is truly free from flow, turbulence, bubbles, foam, vibration, solid content, coating, liquid characteristics and product changes

No calibration required, minimal installation steps needed

Easy terminal connection, unaffected by polarity, with short-circuit protection

No movable parts or gaps, truly achieving maintenance free operation

Has basic electronic self checking function

Visual heartbeat LED display device status

Adjustable switch delay, suitable for turbulence/splash applications

Magnetic testing points make functional testing easier

Compact in size and lightweight, with a short fork length of up to 118 inches (3 meters)

The "fast dripping" tuning fork design can improve response speed, especially for viscous liquids
