SmartLine Guided Wave Radar Level Transmitters

With best-in-class performance, modular construction, an advanced display and the best integration features, SmartLine® Level Transmitters deliver total value across the entire plant lifecycle by helping users: 

• Reduce engineering effort, project costs and startup time
• Avoid unplanned downtime and application errors 
• Increase security against unauthorized access
• Reduce spare parts inventory 
• Shorten time to repair. ​​​​​

Honeywell offers the SmartLine Level Application and Validation Tool that helps users determine the optimal measurement solution for their application.

What Is It?
​SmartLine Level Transmitter uses guided wave radar (GWR) technology and can measure the level of a wide range of liquid products on a large variety of installations within the stated pressure and temperature range. It can be deployed at blending tanks, distillation columns, process tanks, separators, solid silos (inventory) and storage tanks. It does not require calibration or commissioning upon installation, and can measure liquid interface with or without an air gap.

Additionally, the level meter can measure the level and interface simultaneously, and is capable of measuring media with a dielectric constant of 1.4 or greater. A variety of rigid and flexible probes allow measurement in silos and tanks up to 50 m (164 ft) high.  

How Does It Work?
SmartLine Level Transmitter offers:

• A new validation tool to avoid costly errors upfront by validating the level transmitter against the process tank
• A joint, online collaborative engineering session with Honeywell level experts right at users’ desktop  
• Modular design: Some modules are shared with SmartLine pressure and temperature transmitters, further reducing inventory and enhancing flexibility
• Rich, advanced display and local configuration capabilities: In addition to configuring with any handheld device using the new DTMs, users can configure the transmitters through externally accessible buttons, even in an intrinsically safe environment.
• Integration with all control systems: This includes seamless integration with Experion® PKS that provides extended diagnostics, maintenance status display and transmitter messaging. 

What Problems Does It Solve?
​SmartLine Level Transmitters are used in applications where technologies such as capacitance, hydrostatic level or ultrasonic level measurements may have been used earlier. Immune to changes in conductivity, density, pressure and temperature, the level meters offer better reproducibility and accuracy than these other technologies. Since the signal travels up and down the probe, it is also unaffected by the angle of repose of a granular material.
