The Flowline LH25 / LV20 Switch-Tek Level Switch is offered in vertical and horizontal configurations, the general purpose mini-float level switches provide reliable liquid level detection of clean water and chemical solutions with a 15VA or 30VA reed switch output. Media examples include water and sulfuric acid. The polypropylene or PVDF liquid level sensors are mounted vertically inside the tank or horizontally through the tank wall as a high level alarm or low level alarm.

Additional featues and benefits of the Flowline LH25 / LV20 Switch Tek Level Switch include:

  • Simple low-cost level switch solution for basic applications
  • Offered in both vertical and horizontal mounting configurations
  • Dry contact reed switch selectable NO or NC via float orientation
  • Small polypropylene or PVDF sensor body with PVC, TFE or polymeric cable
  • Simple level switch for clean and water like applications
  • Switches can wire directly to a PLC/SCADA or controller
  • Switches can be converted in the field from NO to NC
