Rosemount 2051L Liquid Level Transmitter

The Rosemount 2051L Liquid Level Transmitter is engineered with a robust capacitance-based sensing system that ensures precise and stable level measurement even in challenging process conditions. It provides measurement capability up to 300 psi (20.68 bar) and supports a wide variety of tank configurations through flexible flange sizes, diaphragm types, and seal options. The transmitter offers a standard reference accuracy of ±0.075% of span and a 100:1 rangeability, allowing it to handle both low and high-level variations with high precision. Its welded fill fluid system enhances reliability by eliminating potential leakage points, while multiple wetted material options such as 316L stainless steel, Hastelloy, and Tantalum make it suitable for corrosive and harsh environments.

In addition, the transmitter supports multiple communication protocols including 4–20 mA HART, WirelessHART, FOUNDATION fieldbus, and PROFIBUS, enabling seamless integration into modern process control systems. It offers long-term stability of ±0.10% over two years, reducing the need for frequent recalibration and maintenance. The device also features flexible installation options such as direct mounting and Tuned-System™ assemblies, improving response time and measurement accuracy. With SIL 2/3 certification, Local Operator Interface (LOI) for easy configuration, and compatibility with remote diaphragm seals, the 2051L ensures reliable and efficient operation in critical industrial applications.
