Over 50 years of experience helping our customers solve their level measurement problems.
Rosemount Engineering Co., founded in 1956 to supply instrumentation to the U.S. space program, files its first patents for non-aerospace applications of variable capacitance pressure sensors
The Rosemount 1151 Pressure Transmitter is introduced to the market. An analog pressure transmitter that would set the performance standard for decades to come, and represented a step change forward in terms of stability, reliability and accuracy.
The design project to start developing radar level measurement technology started in 1971, the world’s first functioning radar level gauge was ready in 1972 and in 1973 the first radar level gauge field trial is installed on M/S Sea Scout at Kockum’s yard in Malmö (Sweden).
The first mass-produced system, called the SUM-21 Tank Radar System, is installed on the Norwegian vessel M/S Havdrott. And Emerson acquires Rosemount, cornerstone for the new parent company’s growth into a global powerhouse in the process automation market.
Saab Marine Electronics becomes a world leader in marine level measurement
The TankRadar M Radar Level Gauge is launched to the marine market.
The first HART® 2-wire Ultrasonic Level Transmitter is launched to the market
Launch of TankRadar PRO Radar Level Gauge, designed for applications in the process industry.
Emerson acquires Saab Marine Electronics and later changes its name to Rosemount Tank Radar.
The world’s most successful Guided Wave Radar, the Rosemount 5300, is launched. Featuring Direct Switch Technology and Probe End Projection, the Rosemount 5300 handles longer measuring ranges, obstructions and lower dielectrics, and avoids downtime from interrupted process monitoring.
A new Tank Gauging System with the newly developed Rosemount 5900 Radar Level Gauge is launched. The Rosemount 5900 is the first radar gauge to incorporate 2-in-1 technology, which enables the Rosemount 5900 to work simultaneously as an Automatic Tank Gauge (ATG) and as a sensor in an independent Automatic Overfill Prevention System (AOPS) to enable redundant level measurements or to achieve independent safety and level measurement systems.
The Rosemount 3051S Electronic Remote Sensor (ERS)™ System is launched. The ERS Systems provide DP Level measurements by calculating differential pressure from individual pressure readings. This solution eliminates the need for long capillaries and heat tracing, reducing response time by up to 90%.
Emerson Rosemount acquires Magtech. Magnetic level technology provides reliable, redundant, non-invasive control providing highly accurate local indication with visual indication from 100 feet. Together with a guided wave radar in a chamber, Magtech MLIs offer a low-maintenance solution for both high accuracy and local indication.
Emerson launches the world’s first wireless guided wave radar, the Rosemount 3308, which features wireless technology and enables automation of level and interface measurements in previously inaccessible locations. The Rosemount 3308 also offers quick and easy installations with no cabling needed and it helps to minimize field trips with remote configuration, process information, and diagnostics.
The Rosemount 2140, the world’s first wired HART vibrating fork level detector, is launched to the market. That same year, the Rosemount 5408 Non-Contacting Radar Level Transmitter is launched to the market. Thanks to the Fast-Sweep Frequency Modulated Continuous Wave (FMCW) Technology, which deploys a continuous echo to maximize radar signal strength, the Rosemount 5408 provides more robust and reliable measurement. Besides, the radar is safety-certified, so it’s the ideal choice for functional safety, such as overfill prevention, and supports long proof-test intervals.
The Rosemount TankMaster Mobile Software is launched to the market in April. The Rosemount 1408H Non-Contacting Level Transmitter and Rosemount 1408A Level and Flow Transmitter are launched in June and October respectively.
The Radar Level portfolio advances its process and diagnostic insight capabilities with Smart Meter Verification and Bluetooth® enabled products, which also offer increased reliability thanks to the 80 GHz Fast Sweep Technology. In 2023, the Rosemount 3408 Non-Contacting Radar Level Transmitter is launched to suit a wide range of applications in the process industry, That same year, the Rosemount 1208 Non-Contacting Radar is launched, which is targeted to the water and wastewater industry and general simple applications. Later, the Rosemount 319 Flushing Rings with Integrated Valves are launched to reduce stocked inventory and eliminate on-site assembly costs.
