Flowline AV23-4327-A-B-C Level Switch | Liquid Level Control

Flowline AV23-4327-A-B-C for Liquid Level Systems

The Flowline AV23-4327-A-B-C is a Compact Level Switches & 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.

Performance and Construction Highlights

• Fail-safe relay control of pumps or valves with 0-60 second delay
• Offered in 3 sensing technologies for broad application coverage: ultrasonic, vibration & buoyancy
• Easy setup with LED indicators for sensor, power and relay status
• Rugged polypropylene construction for use in corrosive liquid environments
• Adjustable level switch cars enable sensor adjustment in the field
• Invert switch changes relay state from NO to NC without rewiring

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 AV23-4327-A-B-C, 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.
