Industrial Level Control with Flowline LI90-1001

The Flowline LI90-1001 is a Commander LI90 Multi-Tank Level 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.
