Description Vendor

The Switch-Pro AX13 with Compact Level Controller is a reliable liquid level detection system designed for side wall installation, offering high and low level control, pump or valve control, and optional flash alarm. It features rugged polypropylene, Ryton® or PFA sensors for corrosive liquid applications, fail-safe relay control with a 0-60 second delay, and a NEMA 4X polypropylene enclosure rated IP65. The system is compatible with both ultrasonic and vibration sensing technologies, making it suitable for a wide range of applications including bulk storage and process tank level control. It also includes an optional strobe alert for immediate visual attention to alarm conditions, and an invert switch that changes relay state from NO to NC without rewiring. The system is ideal for corrosive or coating liquids and provides a compact, durable solution for industrial level monitoring.

Use Cases

  • Side wall tank mounting
  • Bulk storage and process tank level applications for high level control or low level control
  • Overflow protection
  • Low level pump protection
  • Not relevant to hydrogen.

Capabilities

  • Relay output interfaces directly with valves, buzzers, alarms, etc.
  • Ideal for side wall tank mounting
  • Great for corrosive or coating liquids
  • Add strobe for optional visual alarm
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.
