Flowline LR11-5421-00 Radar Level Transmitter | Liquid Level Control
Flowline LR11-5421-00 Radar Level Transmitter for Reliable Tank Level Measurement, Monitoring and Process Control
Use Flowline LR11-5421-00 Radar Level Transmitter for industrial level applications. Confirm range, mounting, output and process compatibility before
Flowline LR11-5421-00 for Liquid Level Systems
The Flowline LR11-5421-00 is a EchoPro Pulse Radar Liquid Level Transmitter designed for industrial liquid-level measurement, monitoring or control applications. Use the exact model number when comparing replacement or new-installation requirements, because connection, output, range and enclosure options can vary across Flowline configurations.
Performance and Construction Highlights
- PFA encapsulated antenna and mount for corrosive media
- Configuration via push button display or HART communicator
- 26 GHz. pulse radar is unaffected by vapor or condensation
- 12 in (30 cm) dead band enables utilization of the entire tank
- LCD displays level in feet or meters with percent of span bar
- Optional display mode indicates the echo signal return curve
System Integration
Match the model to the controller, PLC, relay, display or other receiving equipment used in the system. Confirm signal type and power requirements from the product documentation before wiring. Mechanical fit and process compatibility should also be verified before installation.
Before purchase, compare the complete model code with the application requirements. Check tank dimensions, process connection, wetted materials, power or signal needs, measurement range and environmental conditions where those values apply. This helps prevent selecting a similar-looking Flowline model with a different configuration.
Service-Friendly Ordering
For maintenance teams, integrators and OEM users searching for Flowline LR11-5421-00, the model-specific identification makes it easier to match the product to a documented Flowline level-control system without relying on appearance alone.
For replacement work, record the existing model number and wiring or mounting arrangement before removal. For new projects, review the documented installation guidance and leave adequate clearance around the sensing area. Commission the device using the applicable Flowline instructions and verify the output or switching behavior before returning the process to normal operation.
