Non-contacting level transmitters receive update

Emerson Process Management's Rosemount 5300 and 5400 transmitters can now communicate via Modbus and LevelMaster (ROS) protocols


Emerson Process Management announces that the Rosemount 5300 Series Guided Wave Radar (GWR) and 5400 Series non-contacting level transmitters now include the ability to communicate via the Modbus communications protocol. The addition of Modbus enables the transmitter to emulate LevelMaster - sometimes known as ROS or tank - protocol. This broadens the application range for these devices even further and enables them to be retrofitted into existing Modbus and LevelMaster networks.

The new transmitters feature an integral HART to Modbus converter (HMC). This enables up to four external HART transmitters of any type to be connected, and their signals communicated via the Modbus network.

The devices can be configured using Emerson’s Radar Master software, point-to-point via HART communications, or remotely by using HART Tunnelling over the Modbus network. Configuring remotely eliminates the need for technicians to climb up vessels, enhancing safety.

Rosemount 5300 and 5400 Series level transmitters are designed to withstand harsh conditions found in the oil and gas industry.
