Flowline AT12-1620 Controller | Liquid Level Control System Solution

Industrial Level Control with Flowline AT12-1620

The Flowline AT12-1620 is a Thermo-Flo Flow Switch with Compact Flow Controller 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.

Where This Model Fits

This Flowline configuration is intended for level-related process applications where reliable model matching and documented installation parameters are important. It may be used as part of monitoring, alarm, pump-control or measurement systems depending on the model configuration.

Documented Features

• Rugged PP-Ryton® or PVDF sensor for corrosive liquids and gases
• Fail-safe relay control of pumps or valves with 0-60 second delay
• PP enclosure rated NEMA 4X with swivel base for conduit alignment
• Optional strobe brings immediate attention to flow alarm conditions
• Invert switch changes relay state from NO to NC without rewiring
• Solid state sensor is not damaged by over-ranging flow velocities

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.

Ordering Checklist

• Confirm part number AT12-1620
• Compare range and connection requirements
• Verify electrical/output requirements when applicable
• Check wetted-material compatibility with the process

For maintenance teams, integrators and OEM users searching for Flowline AT12-1620, the model-specific identification makes it easier to match the product to a documented Flowline level-control system without relying on appearance alone.
