Description Vendor

The Smart Trak AX23 with Compact Level Controller is a versatile and robust level switch package designed for automatic tank filling or emptying up to 10 (3m) between two adjustable level switch points. It features a compact level controller with an optional strobe, providing a latching 16A relay for pump or valve control. The device is available in three sensing technologies: ultrasonic, vibration, and buoyancy, allowing it to be tailored to various application media. It is constructed from rugged polypropylene, making it suitable for corrosive liquid environments. The package includes field-adjustable sensors, an invert switch for changing relay state without rewiring, and LED indicators for sensor, power, and relay status. It is ideal for use in sump, process, and day tank level applications, with an all-in-one design that requires only 120/240 VAC power. The device is CE IP65 certified and offers a range of features including fail-safe relay control, easy setup, and compatibility with various fittings and mounting options.

Use Cases

  • automatic tank filling or emptying up to 10 (3m) between two adjustable level switch points
  • sump, process and day tank level applications
  • Not relevant to hydrogen.

Capabilities

  • fail-safe relay control of pumps or valves with 0-60 second delay
  • field adjustable sensors allow for field corrections
  • mounts on the top wall of tank
  • ideal auto fill/empty controller
  • internal 16A relay connects directly to values/pumps
  • all-in-one package, simply add 120/240 VAC power
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.
