Level Switches: Application-Focused Level Solutions

Flowline liquid level switches support dependable high-level, low-level, leak and pump-protection switching. They are suited to day tanks, drums, IBCs, sumps, cooling towers and chemical process equipment, where dependable measurement or switching helps reduce manual checks and improve process visibility. Available configurations may vary by model, so match the instrument to the actual tank geometry, media and control objective.

How to choose the right configuration

  • Define the duty: continuous measurement, high or low alarm, leak detection, fill control or empty control.
  • Check the application: confirm media characteristics, switch technology, wetted materials, mounting and relay or controller needs.
  • Plan the integration: verify power, signal, relay, PLC or controller compatibility before ordering.
  • Review installation conditions: account for obstructions, buildup, foam, vapor, temperature, pressure and access for maintenance.

Use the product data sheet for final specifications and approvals. If you are replacing an existing unit, compare the full model number, process connection, materials, cable or probe length and electrical output. Our team can help you identify a compatible Flowline solution for your tank or process.
