Flowline LV20-1201 Level Switch | Liquid Level Control System

Flowline LV20-1201: Selection and Application Guide

The Flowline LV20-1201 is a Switch-Tek Mini-Float Level Switch 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.

Customer Selection Notes

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.

Installation and Commissioning

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.

Maintenance Considerations

During service, inspect mounting threads, seals, wiring, cable entries and nearby process hardware as applicable. If the product is being replaced because of unstable readings or switching, verify the installation conditions before assuming the instrument itself is the only cause.

For maintenance teams, integrators and OEM users searching for Flowline LV20-1201, the model-specific identification makes it easier to match the product to a documented Flowline level-control system without relying on appearance alone.
