Emerson Process Management has announced that the Rosemount 5300 series guided wave radar 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 and enables them to be retrofitted into existing Modbus and LevelMaster networks.
The new transmitters feature an integral HART to Modbus converter, which enables up to four external HART transmitters of any type to be connected and their signals sent 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 the harsh conditions found in the oil and gas industry. They are robust, accurate and reliable, providing users with ‘fit and forget’ real-time level and interface measurement.
Meeting the challenges of tank obstructions interfering with radar
Level Measurement & Control
One of the most challenging applications for non-contacting radar level transmitters is measuring level in tanks with internal obstructions, such as agitators, heating coils, pipes, ladders or baffles. Rosemount non-contacting radar level transmitters from Emerson feature an advanced solution that enables accurate and reliable level measurements in tanks with obstructions.
