Description Vendor

The Switch-Pak AX1X with Compact Junction Box is a versatile and reliable liquid level switch package designed for detecting high or low liquid levels in various applications. It offers three sensing technologies: ultrasonic, vibration, and buoyancy, allowing users to select the most suitable option based on their application media. The package features a polypropylene or PVDF construction, making it suitable for corrosive liquids, and includes a compact junction box for integral wiring termination. It is rated for NEMA 4X and IP65, ensuring durability in harsh environments. The switch can be mounted on the top wall of a tank, with selectable switch points for high or low level detection. It interfaces directly with PLC/SCADA systems and is ideal for high/low alarm indication and control. The product is compatible with various fittings and can be customized with specific dimensions and materials, making it suitable for bulk storage, sump, and day tank applications.

Use Cases

  • high level alarm
  • low level alarm
  • high level overflow protection
  • low level pump protection
  • bulk storage
  • sump
  • day tank
  • Not relevant to hydrogen.

Capabilities

  • detects high or low liquid levels
  • interfaces directly with PLC/SCADA
  • mounts on the top wall of a tank
  • selects length for high or low switch points
  • offers multiple sensing technologies
  • provides relay or reed switch output
  • offers selectable NO or NC contact output
Flowline Inc. Flowline, Inc., based in Los Alamitos, California with over 25 years of specialization in level measurement and sensing products, designs, manufactures and markets liquid and solids level measurement and control instruments for chemical, water, wastewater, oil, and dry solid applications across industrial manufacturers, chemical distributors, municipalities, and energy or food providers. The company's advanced sensing technologies include 80-GHz radar, reflective ultrasonic, guided wave, and pulse radar sensors that measure tank inventories, automate tank processes, ensure workplace safety, and protect the environment across diverse liquid and solid asset management applications. Flowline's product portfolio includes dedicated hydrogen peroxide level sensors, transmitters, and switches offering reliable continuous or point-level measurement of hydrogen peroxide in tank, storage, or day-tank applications—relevant to water treatment and disinfection processes that use hydrogen peroxide as an oxidizing chemical rather than molecular hydrogen fuel applications. The company's non-contact, corrosion-resistant radar sensor technology (as demonstrated in a case study for a Canadian meat processor monitoring hydrogen peroxide and peracetic acid disinfectant levels) offers reliable performance unaffected by foam, turbulence, and precipitation in demanding industrial chemical processing environments.
